Sky view on 11/30/2010 14:50:11 MST Print View

Great review of the new Spot 2. I own and never use the Spot 1 which will live in infamy. I wish I could sell the darn thing but who would want to buy it? Your review would seem to indicate that this new model has addressed the many concerns expressed in the various BPL Forum threads that trashed the original Spot.
Maybe I should reconsider this device.
Two questions: On the Utah canyon trip, what was the typical arc of sky that you had available for transmission? For the trips with heavy vegetation overhead, how much sky was really visible?
Thanks for the comprehensive and thoughtful review. I especially liked your inclusion of the protocols you use.

Good questions.

Percentage of sky view are hard numbers to come up with after the trip. This was field testing and we weren’t directly “measuring” things like sky arc or percentage of tree cover.

For the canyons, one might be able to use TOPO maps to make an approximation of % of sky view using canyon depth and width. But this would vary along the length of each canyon. It would also depend on which side of the canyon you were on and whether you were under and overhang, slope of the canyon wall, etc. In the field, an eyeball estimation would be highly subjective, variable and likely not reproducible from person to person. I’ve done a bunch of canyoneering in S Utah. The canyon system we tested in was neither the worst or the best for percentage of sky view for canyons I’ve visited. Thus the “typical” designation. And yes, there were a couple of narrow areas that challenged the SPOT2 to transmit Tracking Points. They also challenged my GPS that gave some errant positions as well.

The % of sky view from foliage coverage would also be difficult to estimate in situ, let alone after the trip. Height of the trees/shrubs, amount of leaves, density of leaves, density of branches, etc. all play a role. Again, at best this would be highly subjective, variable and likely not reproducible from person to person.

As noted in the review the most challenging area for Tracking Points seems to be in a deep canyon WITH significant foliage. That is an area you would want to be aware of.

But SPOT2’s long term record of a high percentage of Tracking Points from a variety of canyons and foliage situations in many locations over many days leads us to believe that the SPOT2 does a good job of Transmitting Tracking points.

Sky View again on 11/30/2010 15:33:01 MST Print View

Thanks for the honest answer. I realize that after the fact it is difficult to remember the amount of sky visible to you. I suppose I was more interested in a general answer along the lines of "most of the time we could see 30% of the sky in the canyons" or "the sky was pretty patchy under vegetation" -- that sort of thing. As I am sure you do know, the original rarely worked even if you had an almost 180degree sky to work with. I guess that your varied experience with the Spot 2 over a lot of terain seems to indicate a pretty impressive performance profile, but I am a once burned buyer, so...

I don't think BPL reviewers are rubber-stamping products. So when they say, within the first four lines of the article "Overall Rating: Highly Recommended" I believe they confirmed the product works as advertised.

(SPOT1 did Not get a very good review.)

The data gaps due to the combination of trees and steep canyon were mine, so I'll add to Alan's response. We had two gaps of about an hour each along the Terrace Creek and Pine Ridge Trails in the Ventana Wilderness. During the gaps on our Ventana hike, the tree coverage was 80-100% -- tall conifers (Redwoods and Doug firs) with understory of maples. Tanoak and Coast Live Oak, both very dense-canopied species, fill the gaps caused by fallen conifers. Very dense shade on the floor of mature redwood forests, as anybody who has been in one knows.

The gaps occurred when we were 1000-1500 feet below the adjacent ridges on a north-facing slope of 30-45%. On the rest of our Ventana hike the transmission was fine. On the south and east and west facing slopes, the drier growing conditions means the redwoods don't dominate, and it looks like as long as we weren't in the deep redwood forest we were OK.

why I carry the SPOT Tracker on 11/30/2010 16:33:52 MST Print View

I didn’t include this in the review because it’s really a personal story and not a product review, but I’ll share my rationale for starting to carry the SPOT device.

In 2009 I spent five days at a B&B in Wales nursing a torn knee ligament, while Jim continued our hike on the Cambrian Way without me. The proprietor of my B&B was retired from the North Wales Search and Rescue team, and had once served as the head of that organization. We had many hours to talk about SAR, Snowdonia, the fierce storm conditions Jim was hiking through, and so on. Jim and I were not carrying, and had not ever carried any electronic devices while backpacking (no GPS, phone, PLB, SPOT).

I explained to the proprietor why Jim and I do not carry a GPS or cell phone: old-school, started hiking in the 1960s, proud to be self-reliant, will persevere to rescue myself, prefer the way it was back in the good old days, too much weight, blah, blah, blah.

Finally, the proprietor politely told me “given today’s technology it is a selfish act to be out in these mountains without a means of communicating, because the SAR team members risk their lives conducting searches. Jim may not want to be rescued, but if he doesn’t show up eventually there will be a SAR, and people will risk their lives searching for him.” Oh, you mean it’s not all about me! That’s a different story, and to me it was a compelling story.

Subsequent to that hike in Wales and England, we have carried the SPOT tracker when we go backpacking. I think of it primarily as a way to avoid extensive SAR. The odds that I will have a life-threatening injury that requires a 911 call is small. It is more likely that at some point I will have a delayed exit; I’ve come precariously close to a delayed exit twice in perhaps a hundred backpacking trips, not a large number, but a sober reminder of how suddenly something can go very wrong. With the SPOT device, I can prevent a SAR by communicating that I am OK even though I’m late due to weather or injury. And, if I have situation that prevents self-extraction, I can request non-urgent assistance, which is better for all parties than waiting until a day after my planned exit and then starting a full-blown search effort.

A GPS device combined with a functioning cell or satellite phone provides the best means for seeking assistance in case help is needed. Those devices allow two-way communication so that the party seeking help can get instructions and advice, and the agency providing help can get more information about the nature of the request. In most of the areas we hike, cell phone reception is not viable. And I’m not prepared to spend the money to carry a satellite phone. In the absence of a phone, the SPOT provides a combination of useful functions.

The 911 function of the SPOT is matched by a PLB device. The disadvantage of a PLB is that the only thing you can do is request urgent assistance. There are numerous scenarios where an extensive search and/or an urgent rescue effort can be avoided by using the other functions of the SPOT device.

In addition to requesting urgent help when there is a threat to life or limb, to requesting non-urgent assistance, to indicating that a delayed exit is not cause for concern, to providing comfort to families who might otherwise worry, we have found that the SPOT Tracker provides an enormous amount of vicarious pleasure to friends and family. Alan and Amy (and others) have watched each other’s trips with great joy. We consider it a gift to each other and to our friends and family to carry the extra few ounces of gear in order to allow our friends and families the pleasure of vicarious hiking trips.

Quite a change between Spot 2 and the old Spot! From "Unrated" (i.e. "We cannot rate this product") to Highly Recommended is a big jump!
And wasn't the first review originally "unsatisfactory" or some such thing and then changed? It's great to see a company who pays attention to reviews and has been able to overcome the problems in such a short time!

If the improvements are due to your first review, then all power to BPL!

For now I'm sticking with my McMurdo FastFind, as I'm only interested in help in case of dire emergency, not in letting everyone know where I am at all times (I'd really rather not!). I can see that a lot of people do want this info sent to their families, though. It's great to know that nearly all the SPOT transmissions will get through!

Maybe SPOT 3 will have text messaging (it would be great to be able to tell SAR the exact nature of the problem so they can be prepared) and soothing music to play to you while waiting for rescue. Seriously, though, I suspect that if SPOT adds a few more bells and whistles to what they have now, I will be sorely tempted!

What Amy says in her post above is most telling; I urge everyone to read it!

Amy's Share on 11/30/2010 16:55:34 MST Print View

Thanks Amy for sharing your story.
I agree with the proprietor/SAR veteran. That is why I have carried a SAT phone on most of my trips. I rent it, but that has become more and more expensive since the first time I did at about $60 for a full week including several minutes a day talking with my wife to let her know I'm "OK". So, now I am looking again for the magic bullet and had not looked at SPOT because of my first experience with them. I just called a friend of mine who recently purchased a SPOT and was extremely satisfied with its performance on a trip along the John Muir Trail for a week through snow sleet and rain. He indicated that the SPOT did what it was supposed to do and he directed me to the map of his track on the internet. He bought the SPOT 2.
So, I guess I should rethink my aversion to the device and look into it again.
THanks again for the review. BPL keeps me from getting too hide bound in my thinking.

my comparison on 11/30/2010 17:14:25 MST Print View

I've been using a Spot II since April of this year. It has been used in Utah and Colorado, from the tops of mountains to the bottoms of canyons.


My reception/transmission rates are almost identical. I also inform those receiving the messages that this device does not have 100% reliability and to not worry if messages are not received on a regular basis.

I chose this locator over a PLB for one reason - the tracking feature. Some time ago I had a brother die on a mountain in New Mexico. As hard as his death was, the week it took to find him was almost unbearable. Like my brother, I enjoy solo trips. Having the tracking mode on my SPOT II gives my family and I a little more peace of mind, especially when I get off the beaten path, so to speak. Some times I think people automatically assume in an emergency they are going to be conscious or alive to active their PLB, and that is not always the case.

Re: Sky View again on 11/30/2010 17:14:50 MST Print View

Let me state that I am coming from the GPS industry.

It is extremely difficult to place numbers on the view of the sky. It varies with your position on Earth, the surrounding terrain, and the type and quantities of satellites overhead. It is also extremely difficult to place numbers on overhead vegetation and how much sky it blocks. Phrases like "30% of the sky" are completely undefined, even if it might be possible to measure it with instruments.

It is possible to make statements about sky view when you are in a completely open field situation, like horizon to horizon. But there, you won't have much question about sky view since it won't be a problem.

Great review, but something I found out the hard way...... on 11/30/2010 17:30:50 MST Print View

during my trip to the Sierras last year. I sent three messages per night...once I received the "message sent" confirmation, I started the process of sending another. I had planned to send three "OKs" per night to make sure they went through..When I returned home, I found out that for 4 days, no messages were received by my wife NOR to my email address (I wanted to track the trip). I called the customer service line and they told me I should not have turned it off after the confirmation and to allow it to send for 5 minutes....

So, I am just glad I learned that lesson now....anybody else have such an experience?

So, the bottom line is once you send a message, to ensure it goes through they are telling me to let it transmit for 5 minutes.

Actually, for an OK or Custom message you should leave the unit on for 20 minutes (the unit's OK/Check-in light will go off when it is done). The SPOT sends three messages in a 20 minute period. This is why it is so successful at transmission of the OK message. Only the fist successful transmission of the three is kept and the others are discarded.

Help and SOS messages are transmitted continuously every 5 minutes. Again, the greater the number of attempts the higher the probability of getting the message through, even in limited sky view.

bad reviews on 11/30/2010 17:44:17 MST Print View

Spot2 has a fair amount of negative reviews here:

just one of them:
"By B.GP - Aug 28, 2010 - Full review provided by REI
Pros: Compact Design
Cons: Unreliable
I've been thru-hiking the PCT since April 2010. I have always made sure to find a clear opening to the sky's to send any messages and have followed all the directions that came with it. Unfortunately, SPOT messenger has failed me every other day. Every night I send an OK message to family and friends and they only receive it, at best, every other night; usually 1 out of 3 nights. I let the SPOT run through the entire cycle of sending and receiving, but it still makes no difference. I've never had to use the SOS button and I can tell you that I do not feel confidant that it would go through. There website has many, many flaws. The navigation of the website to entering emails and phone numbers of the people that should be receiving the messages have many errors and buttons that perform incorrectly. They did a recent upgrade to there site, and still, all the same flaws are there including a few more. [...]I would describe SPOT as an amateur company with a great idea. I think they will need a couple more years to fix their flaws [...] The technological aspect of SPOT is there, but it needs much improvement before it becomes a reliable service."

clarifying SPOT transmission processes on 11/30/2010 19:17:32 MST Print View

Some folks reading this thread don't have the device, so let me clarify to put some of the comments and questions in context.

The SPOT picks up a GPS signal to find your location. It knows if it received the signal, so the GPS-fix status light is a reliable indication of GPS reception. If the GPS-fix status light is red, then you know it's not getting your location fixed, if it's green, it has your location.

SPOT broadcasts your messages to a different satellite system. It does not receive confirmation from that transmission. The green Message-Sent LED indicates that the message was sent, but not that it was received. For this reason, it's important that the folks at home know that an absence of an OK message or tracking points is NOT an indication that there is a problem. And it’s important for hikers to know that they will be unaware of whether a transmission was successful; the SPOT marketing material does not highlight this aspect of the device. If a hiker were in trouble they would need to factor that into their planning process.

As Alan mentioned, OK and Custom type messages are duplicated for three transmissions over 20 minutes in order to increase the odds that a satellite will be in position to receive the message. The Help message is sent every five minutes for one hour. The 911 message is sent every five minutes until cancelled or until the batteries fail.

In order to increase the odds for a message to successfully go through, one could leave the device on for the completion of the cycle (20 minutes or an hour), and then initiate it again. In the protocol that Alan and I use, an absence of an OK message is no reason for concern, and we consider even spotty indication of forward progress to be confirmation that the hiking party is OK; one or two data points per day is all it takes to know that there is forward progress, and we have been consistently getting 5 or 6 data points per hour.

Both Alan and Amy leave the device on for 20 minutes after initiating OK. In our field tests, the only OK messages that did not go through were those sent when I had Alkaline batteries with the red low battery warning displayed (a use clearly out of bounds of the device’s specification). All other OK messages have been successful. Our testing did not include long periods in heavy forest cover, and it will be interesting to see transmission success data from people using SPOT in the rainforests of the tropics or the Pacific Northwest.

The lack of the ability for a hiker to confirm that the message was received means this is not a fail-safe method. Compared to my prior method (i.e. nothing) it is a big improvement. But people seeking greater security might want to carry a sat phone instead. Alan carries both a sat phone and a SPOT, and found that the SPOT transmitted messages in places where he could not get sat phone reception, so the sat phone is not unambiguously more reliable. It does, however, have the advantage that if you are talking to somebody you know they have received your message.

In addition to Russel's comment...

The first release of the SPOT 2 had problems and was recalled. When reading a review (like the one copied by Steve O from another site), it's important to make sure you know if they are talking about SPOT 1, SPOT 2 pre-recall, or SPOT 2 post-recall version. Our field testing was with the SPOT 2 post-recall version.

More information about the recall is below:

And the sat phone is heavier, larger, and more expensive both on initial cost and monthly service cost.

And as Amy noted, if you are going to have trouble getting SPOT messages through, you are likely to have problems initiating a sat phone call. Both systems use the same type of satellites.

reviews on 11/30/2010 20:14:44 MST Print View

Before purchasing my Spot II I spent a great deal of time looking at reviews. It became evident that the device is not without problems, especially the early models, and I have no doubt that many are legitimate. As such, I purposely bought mine from REI (luv that return policy) so that it could be returned if it failed to work to my expectations.

That being said, I began to notice that more than a few of the negative reports were regurgitated stories many times removed from the original source. (I fully expect to see the tragic account of the 2 men on a Colorado peak mentioned in this thread before we are done)

Also, part of the reason you see so many comments on the performance of this locator compared to PLB is because you can actually use them prior to an emergency. They get used frequently and often. I send out messages on my Spot II on almost every trip. Had I purchased a PLB it would have remained in my pack untested and unused, thankfully.

I've been using a Spot 2 for most of this year. It's a cool way to share your adventure with family and friends, though as with all electronics it can fail, and that ought to be planned for. Don't share the tracking page with especially histrionic, non-adventure literate relatives.

For those interested in how to kill a Spot, know that the immersion waterproof for 1 hours is quite accurate. On a packrafting trip I attached mine to a strap which came loose, and the Spot floated off into oblivion. Oddly, it sent "Help" messages every five minutes for an hour (as it floated downstream) before dying. No emergency calls or emails were sent, and Spot CS was unable to explain this oddity.

SPOT has some valid reasons for not putting a LCD display on the unit because a) LCD displays do not work in low temperature environments and the SPOT is intended to work in Arctic and Antarctic environments and the cold of very high summits, b) the LCD is more delicate to being shattered in warm environments—the current SPOT is extremely rugged in terms of impact resistance in comparison to something like a GPS where the display is easily damaged on impact.

An alternative possibility for the 1 hour:

SPOT will send your message and current GPS location every 5 minutes for an hour for redundancy and overall reliability."

So, the SPOT may have still been operational if you could ever locate it. It just stopped sending after an hour as it was designed to do.

I carried a SPOT on a packrafting trip in AK for a week. It did fine on the water, although mine stayed attached to the boat...

surveying others' experience on 11/30/2010 23:40:53 MST Print View

Thanks for the thorough review. I really appreciated follow-up comments from Amy quoting the experience of the SAR volunteer and your respective message protocols. I have been interested in this product since the first model came on the market. Enthused after reading the very positive BPL review, I went on to survey the reviews on the REI site. Of these reviews 14 rated the device as reliable while 19 found them unreliable. The accounts appeared to me to be first-person accounts and not recycled myths. The theme of all the reviews was the device is terrific unless it fails, and device failure seems to occur for about half the people writing reviews. Some of the negative reviews were written after the recall of 9/27/10, but obviously the purchases could have taken place earlier. All of the negative reviews emphasized that the Spot customer service was seriously substandard if a problem did arise. It sounds like Alan and Amy had the benefit of having a device that operated properly, but there may be quality control issues that have not been resolved. If all the problems have been taken care of and the bad reviews cease, a Highly Recommended rating may be justified. But with electronics like the Spot and the Steripen, one expert's extremely thorough review may not be a reliable guide to others' experience. For these kinds of devices a broad survey of users may be a more reliable indication of what one might expect.

not perfect on 12/01/2010 03:20:16 MST Print View

I had a Spot 2 with me on my 5 weeks (hiking and packraft) in West Greenland this summer - short version: only about 60% of my messages arrived.

I had to exchange my new device immediately after it came to me because of these technical problems and after around 6 months (!) I received an exchange Spot2 - obviously not new, but a used one.

I sent a mix of OK and custom messages (set up camp, etc.) every evening, interesting points - I am not sure yet if there is a difference between the two, but could be.
Even in a perfect clear sky, sunny, no canyons, no trees, waiting for at least 20 minutes until the light is of - only 60% of the messages came through.
Worst were 4 or 5 days in a row without messages! I didn't use the tracking function - it is obviously more redundancy, sending only 1 or 2 messages per day seems not enough for reliabilty.

Maybe it is because Greenland is on the edge of the served area?

The label and colour on the two buttons for Help and SOS is already disappearing.

I still think it is a good thing and I would recommend it too, but knowing and accepting that it is not perfectly reliable should be part of the deal.

The main advantage is the ability to send custom messages typed in the field.

I don't use the tracking mode on my spot. However, I do send out an OK message each morning at breakfast and one at dinner. In my experience, both in Scotland and in New England, about 10-15% of these OK messages are never received. My wife and I have come to accept this limitation but I can't say we're happy with it.

Finally, the review seems to suggest that the SPOT web site is usable. NOT. It's the biggest piece of usability crap I've seen in a long time. Trust me. Set up your messages once and avoid trying to use that bloody site. It's awful.

I lead wilderness high adventure treks for a scout troop. We are out from between 5-14 days. I have used my Spot1 to send ok messages at the end of each day and to warn of problems. We get into some very deep and remote canyons in New Mexico and Arizona. It has worked fine, always. I have no need for it to track our movements throughout the day. I personally know of several lives which were saved with the spot 1 in the Superstition Wilderness though unfortunately I also know of some prank and just plain stupid distress calls (including one for a dog that had a cactus thorn in it's paw). While I will move on to a spot2, being a gadget person, I refute what seems to be a blanket hatred of the spot 1 by some folks.

"SPOT has some valid reasons for not putting a LCD display on the unit ..."

The temperature and fragility of an LCD position display excuses don't wash with me. It's not all that difficult to ruggedize a small display, and if I need to get a fix when it's -40, I'll warm it up under my jacket.

As a test to see if your 'OK' messages are being sent, you can set up your account to text message your own cell phone. My cell phone has rung as little as 20 seconds after the SPOT reports that it has sent out the OK message.

Of course your cell phone will only ring if your in a service area.

Re: SPOT - pre-trip message testing on 12/01/2010 08:41:15 MST Print View

>As a test to see if your messages are being sent,

Excellent point Daryl! It really makes sense to test all message types (but SOS) pre-trip. Even better done again in the town before you hit trail head if you have a cell phone. Not only does this test the unit, it also familiarizes you with its operation. And it also gets local ephemeris GPS data which will speed operation of the unit when you hit the trail. From the review:

"Pre-trip, the SPOT2 user sends tests for all four types of messages, OK, Tracking, Custom, and Help to all Responsible Parties/Emergency Contacts and makes sure they receive all email and text notifications, and that all messages show up on the Web tracking page."

new units on 12/01/2010 09:01:09 MST Print View

As an owner/user of an original unit, I have had one delayed message out in several years of using my unit. I always felt if I had the patience to wait on an esbit to boil water I had the patience to wait a bit on startup of my unit. I admit I have never used the track feature on my old unit but I do bread crumb at times through the day. I'm really happy to see the new units improvements and if lots of folks that were unhappy about the workings of the original units like the new units then I am sure I would be overwhelmed at how well the new unit works and the fact it is about half the weight and size of the old units. From an owner that lost a unit, take out the insurance for a lost unit. My replacement was headache free and fast. I'm very happy to see the new gen. units are making folks happy now.

PN60w spot on 12/01/2010 09:04:07 MST Print View

I have a black PN60W with Spot. Yes it is the bomb. Used it for a 3.5 day 70 mile trip just recently. My family recieved all my text messages everyday, evertime i sent them. The battery life is amazing. I was at 95% after the trip. I switched it on and off. the only downfall of the delorme units is the software, which you should give yourself AMPLE time to learn several weeks before you intend on using the unit for a trip. Once you learn the software, Its great. Never had to use spot for emergencies(just for texting), but nice to know its there.

PLBs vs SPOT on 12/01/2010 10:18:53 MST Print View

>The disadvantage of a PLB is that the only thing you can do is request urgent assistance.

Now, there is which takes the PLB's self-test and sends an "OK" email to one whomever (Plus service - you get 5 whomevers).

I would like to hear more from adventurers using PLBs. As I understand it, SPOT uses the same (low orbit) comm sats used by sat phones (I've had limited success with sat phones). Whereas, PLBs use the 406 MHz capable of penetrating tree/cloud canopy to SAR sats directly (no 3rd parties).

The ACR 'SarLink View' has a GPS coordinate window too.

Right now, I'm a shopper, not a user (of any of these tech) - so I would appreciate learning more from you guys.

Re: Delorme GPS with SPOT anyone with experience. on 12/01/2010 11:36:28 MST Print View

Hi Shontelle,

For anybody who wants to carry both a GPS and a SPOT (or other emergency device) they're a viable option. With Delorme I've only used the older PN20 in the field. It has very good sensitivity and a good feature set, offset by clunky controls and menus, and ponderous response on the go (i.e., slow screen refreshes while moving).

Playing with the newer Delorme models convinces me they've addressed the speed and processing issues, making the PN60 series technically a very good GPS that's the equal of other top handheld models. Of course whether one likes the display, menu system, controls and general shape is a very personal thing--some will prefer Garmin, Magellin, etc.The Delorme maps are pretty good and they offer satellite imaging, which adds a whole other dimension to backcountry navigation uploaded to a GPS (although it cries out for a larger display).

But pairing with SPOT sets the PN60w apart from everything else, significantly enhancing SPOT with the personalized texting. This SPOT unit is much smaller than even the SPOT2 and takes only two AAA cells. It can also be used as a standalone unit, but will only send an SOS by itself.

The pair retails at a high price but I've seen it for as little as $350, which seems attractive to anybody who happens to be in the market for both a GPS and a communicator.

Here's a PN60w review that includes a link to a review of the SPOT unit.

SPOT Reliabilty on 12/01/2010 12:07:34 MST Print View

Some good/bad comments from the perspective of someone who owns a lot of both SPOT 1 and 2 models - my company has rented them out since they first came out a few years ago.

These units are valued by those at home much more than those in the field - they are lot more worried about safety than the user is.

We've never had any problem with the web portal setup, although maybe we're just used to it since we apply it so much.

We rarely get complaints about reliability in the field, but when they go out, it's a 100% failure - working fine one minute; dead the next. SPOT 1 was as reliable as SPOT 2 in our experience, but SPOT 2 captures a signal a lot faster.

SPOT customer service has been pretty good and responsive, but there's only so much they can do.

The units are frequently lost by the user - be sure to use a lanyard. The belt clip isn't that secure. Despite worthlessness in the hands of another, they are also occasionally stolen.

Test contact emails and cell phones at home before leaving on a trip. Assume some percentage of OK messages are not received, so send at least 3 or 4 a day to better ensure daily receipt at home. There is no pattern to when they aren't received (open clear sky may not complete; a canyon transmission may complete in 2 minutes). Absolutely tell contacts that absence of a message does not mean anything is wrong.

Leave the SPOT unit on for at least 20 minutes for every message transmission effort.

The HELP button has limited practical value - most users are not in a location where a friend or family contact can actually help them out. We suggest using that button as an alternative message conveyance, with a interpretation protocol established with the contacts before the trip.

The SHARED PAGE function showing the cumulative tracks seems to be preferred by those at home over the periodic message postings.

The button text on the unit wears off quickly.

The contacts you list for the 911 setup should be levelheaded and knowledgeable about your trip - they are going to get a call from the monitoring station first when the 911 rescue button is pressed.

In those rare cases where a renter has placed a 911 request, they were in fact rescued in a reasonable time, so the system does work.

In three more years, I will retire and plan to move to either Oregon or Washington state.

It will if you have it configured to do so. I used the 'HELP' as a sort of poor mans tracker before I purchased the 'Track' option. It would drop a 'HELP' flag every 5 minutes along my route. But I always forgot to repress it after 1 hour.

On the fence about SPOT 2 on 12/01/2010 17:13:53 MST Print View

I would echo the posts of Steve O and Bob R - I have seen a lot of online reviews (that appear to be firsthand accounts) warning of message failure, unit failure, and poor or rude customer service from the SPOT folks. The REI reviews are a great example of this.

Counter to that is the experience of a frequent hiking companion of mine who owns a SPOT 2. His is one of the recall replacement (refurbished) units. On the trips we have done together, it has performed flawlessly. He reports it always works that well.

Now adding to the positives is BPL's glowing praise for a pair of Post-Recall SPOT 2's, even giving them a Highly Recommended rating. Plus BPL now reports a better web interface, despite others here who still malign the SPOT website useability. I didn't see any commentary on customer service.

So I am left more conflicted then before. I would like a messenger like SPOT 2 for reasons Amy noted, and for the comfort it would bring my family and friends when I am in the middle of the wilderness for a week or two. But I am really not anxious to invest in or depend on a device for this manner of communications when it has so many critical reviews floating around.

For now I guess I will keep doing it the old way - leaving a detailed trip plan and renting a sat phone when I am on prolonged solo trips.

"LCD displays can freeze, but LED do not. SPOT III?"
I had the opportunity to test a low temperature LCD display for a product I designed. It didn't freeze per se, it just changed more slowly as it got colder. At minus 40, it was unusable for my application because the seconds display took more than a second to update which made for a jumble. A GPS readout that updated at a slow rate, say less than a minute would be legible at -40. I think that would cover most applications.

Yes, most LCD displays get increasingly sluggish as the temperature dips to the point where digit changes kind of blur together. That can be mitigated by placing a heater behind the display, but that requires battery power. If you leave the whole unit inside your coat for a while, it can operate, but it won't do a good job of transmitting or receiving signals inside your coat.

I have used the SPOT in Yosemite and on the AT in the VA woods when cell phone reception was no available.

Here is what my wife saw at home in MA when I stopped by this area of Yosemite. Zoom in and the name of the lake appears. As I was hiking along the PCT just before I sent the message, I passed two Park Rangers hiking along with a hiker who had become ill on the trail. Even thought the Rangers carried a satellite phone, they had found it unreliable. Their connection had been dropped.,-119.41841&ll=37.99367,-119.41841&ie=UTF8&z=12&om=1

It had been raining when I sent the following SPOT Ok message from this campsite in the woods along Virginia Canyon in Yosemite:Virginia Canyon forest,-119.33882&ll=38.03432,-119.33882&ie=UTF8&z=12&om=1

I sent a test message from my backyard. Zooming in, one can see the arrow on the exact spot where I was standing. My house driveway and garden are clearly visible, as is the spot on my lawn where I stood. I think the SPOT is a great device.
I a lost hiker had both a cell phone and a SPOT, the contact person could zoom in on the location of the lost hiker and tell him which way to travel to safety. A lost hiker in the woods could be very close to a trail, or a lake or road, etc. he cannot see.

I appreciate the reply Alan.

If I were to get the SPOT 2, I would hope not to need their customer service either, but their reputation is so bad that it's actually weighing into my decision on whether or not to get their device.

I am glad to hear of your positive experience with the web interface - that helps.

Ultimately my decision on when to buy one of these devices is affected by how fast the technology is moving. I suspect we are within just a year or two of a moderate-cost device that will allow custom text messages. The Delorme PN-60W with separate wireless SPOT pod is already there of course, but by my count that's actually two devices. I am looking for one.

User error? on 12/05/2010 14:18:02 MST Print View

Wow. I have been using the SPOT2 since it came out (I never had a SPOT1, I waited for the improved unit) and have been impressed as hell with it. Having read this thread, I started looking up these scathing reviews.

I'm sure there are people who have had a bad time with their SPOT2- as was mentioned they are electronic devices and electronic devices sometimes fail- but at least a few of the more scathing reviews of the SPOT2 were written by people who really don't know how to use the device. I found a couple that seemed to indicate that the user was expecting instantaneous transmission, and they were saving battery life buy leaving the unit off, turning it on to send an OK, and then turning it off again long before the 20 minute transmit window. No wonder they didn't like the transmission reliability!

Heck, I can only recall half a dozen or so dropped messages from my unit in the past year- and they were all points on the Tracking feature, not "real" messages sent by pressing one of the buttons. (FYI- I've been hiking in Colorado, not "Kansas.") As I said, I was actually expecting it to work much less reliably than it actually does, having read a lot about SPOT 1.

Anyway, I suspect that a decent percentage of those bad reviews represent user error, not a failure of the device. You can fix a device, but you can't fix stupid. (Just kidding- I actually made the same mistake. I would send a final OK message when i got back to my car, but then turn the unit off soon afterward to pack it in the vehicle, and noticed that those final OKs never went through, so I read the manual more closely.)

Doubtless, some failures are real, too. As I said, electronic devices fail. But I've generally been very impressed.

What I cannot speak intelligently about is SPOT customer service. My only experience in that area was returning my original device for the recall. I returned it immediately when the recall was announced (actually, before I'd ever used it in the field) and as near as I can tell I did get a new unit in exchange. And it arrived much more promptly than others described- about six weeks- but perhaps that was because I was one of the first people to send it in for exchange.

All of the stories about rude customer service reps and problems canceling the service do sound distressing, though. Especially since I need to cancel my service, as I'm leaving the country for the next year and won't be able to use it.

user error and reviews on 12/05/2010 21:14:25 MST Print View

At least some of the REI reviews are not for the SPOT II:

"I've travelled with a spot on several trips, one of which was a hiking trip to Patagonia through the glaciers. I had spotty unreliable service while trying to "breadcrumb" my hikes and send messages to those on my contact list. With a 50% connection success rate I returned the device to REI after my 1yr contract with Spot was up. I considered buying the Spot II as it was smaller with promises of better service; however, after contemplating the purchase in the store I decided against it."

Many of them refer to the SPOT rather than SPOT II. Could the reviews for the old model have been folded into the new one? Amazon is terrible for this.

There are also many ways for the user to screw up, like using alkaline batteries, or not keeping the device outside their pack and facing the sky. I'm inclined to believe the positive reports of a few technically adept users.

Nevertheless, the manufacturers appear to have mediocre quality control and really lousy customer service.

SPOT1 and SPOT2 comments on 12/07/2010 14:56:51 MST Print View

From your field tests of the SPOT2 it sure looks like the operational envelope may have been expanded quite significantly. However you should have also performed a side by side field comparison with a SPOT1 to prove that it really is all the SPOT2 internal improvements rather than some unknown changes made in the rest of the communication system or a combination of both that give you such good results.

I have had very good luck with my SPOT1 probably because I am very familiar with the technology involved as well as being a professional electrical engineer with many years experience in digital design, satellite communications systems, GPS, real time embedded software, etc. and I operate my SPOT1 within its limitations which were pointed out in the SPOT1 review and confirmed by my own field tests. I do not see any reason for me to upgrade to a SPOT2.

The problem with these systems is that the general user is just a “button pushing appliance operator” who does not really understand the underling technology hence he/she can easily make a very simple operational mistake rendering the device essentially useless. It behooves the user to read and follow the vendor’s instructions. My personal opinion is that the SPOT1 directions and theory of operation was lacking quite a few important details which led to quite a lot of obvious user confusion and poor user results; hence a lot of very shrill negative postings where made about the SPOT1.

I am curious to know in which Utah canyon complex you tested the SPOT2. I would guess the Grand Gulch/Bullet Canyon area. As you point out, I am quite sure someone is going to try and use a SPOT in a Buckskin like canyon and complain that it does not work. I would be surprise if any portable communication system would work reliably from the depths of Buckskin near the “Cesspool”.

PLB for me on 12/08/2010 08:43:05 MST Print View

I chose a PLB because I wanted a rescue initiation device. While my PLB (SARLink) will do OK messages with the 406Link service, I am unmarried and don't really need to be in constant contact with anyone for peace of mind. I do understand that a lot of folks have good reasons for letting loved ones know where they are regularly, which the SPOT generally does well.

While fishing a narrow canyon, I slipped at the top of a large log jam and bounced my way down until I was flat on my back on a gravel bar. I was uninjured, but a look at my path down the trees showed that I was extremely lucky to have not been stabbed by one of the many branch stubs sticking from the logs. During that same trip, I had attempted to use my GPS, a Garmin 60CSx that is generally regarded as having excellent satellite reception, and had no luck. So, I used that as my benchmark when deciding between the SPOT and a PLB.

The PLB uses the GEOSAR sat system as well as the LEOSAR for doppler positioning, and has a homing signal. Most importantly, the PLB signal is 5 watts as opposed to the SPOT's 5 milliwatts, so it will cut through heavy tree cover. An OK message sent in the above mentioned canyon was successfully transmitted.

I let people know where I'm going and when I'll be back. In my case, they don't need to know where I am each day, but if I need to send an OK message I can. I pay $60 a year for that service, but if I choose not to pay for the service, I can still contact SAR, since that service isn't part of the subscription, unlike SPOT.

I wonder if it's fair to compare the 2 devices. A SPOT is more of a communications device that can be used to contact SAR, while a PLB is a rescue initiation and homing device that can also do some comunication. Each one has strengths that offset the other's weakness.

Fantastic device, track progress shortcut on 12/12/2010 09:59:26 MST Print View

I've found the SPOT 2 to be exceptionally reliable and accurate. I used it this summer while hiking the Montana section of the CDT. The device reliably broadcasted my location each time in temps down to the mid 20s F. Locations were dead-on accurate.

One feature I'd like to mention is the Track Progress function that was extensively reviewed in this article. It's important to note that the Track Progress function adds an extra $50 to the $99 subscription for the ability to broadcast your location every ten minutes.

If you don't need to record your location every ten minutes, but would still like to keep track of where you've been, you can track your progress for free by using the "check in/OK" message feature. This feature sends a pre-arranged email message to as many as ten addresses with your exact latitude and longitude coordinates. Someone at home can easily plug this info into a custom google map. If you only are interested in recording your position once or twice a day, I'd recommend this method. However, if you really need to know your position more frequently, I'd recommend buying the Track Progress feature as the check-in/OK feature takes roughly 20 minutes to deliver an accurate message.

On my CDT trip, I used the check-in/OK feature to make the following map:

Re: Battery? on 12/23/2010 06:26:51 MST Print View

You are exactly right. You can leave it off and just turn it on to send an SOS when needed. It should not use the batteries.

But most electronics equipment have a slight drain on batteries when not turned on. Given the nature of the SPOT, I would imagine that this drain would be designed to be quite low to nonexistent, but it is not something we tested. To be safe I would install fresh batteries at the beginning of my thru hike.

A few minor caveats:

1) The GPS in the SPOT will acquire a fix faster if it has been used recently.
2) There is a "safety" value in laying down some sort of breadcumb--even just an OK message once a day. In case you are injured and unable to activate the SPOT somebody would know where to start looking for you (i.e. after your last OK message).

In the one OK a day use scenario the batteries would last a very long time. Over 300 days.

Also at around 120-140 hours of battery life with a decent sky view, you'll get a lot more than 3-6 days use out of a set of batteries. Operated at 10 hours a day you'll get more like 12-14 hiking days.

Spot Message Issues on 11/22/2011 16:02:00 MST Print View

Twice in the last year I used my SPOT locator and had serious issues with it. Just this past weekend I used it during a hike on the Eagle Rock Loop in the Ouachita Mountains of Arkansas, near the Albert Pike Recreation Area that experienced the deadly flood two years ago. And yes, there was another flash flood this weekend when the Little Missouri River rose over 8' in less than four hours. I got out safely and fortunately my wife was unaware of the severity of the situation.

But out of ten okay messages that I sent to my wife over a three day period, all with a green signal indicating success, only three were ever received by my wife. The other seven never got through. Every time I made sure to be in an area clear of trees with as good an open area as possible. I will note that I did not leave it on for twenty minutes each time to give it the opportunity to retry sending the okay message two more times. To do that, you have to remain stationary and during the day, I tend not to stay stationary that long. I falsely assumed that if the green light indicates that it was successfully sent, it is sent. But apparently the more I read the more I realize that a problem with the Globalstar satellite results in a message being sent but not necessarily transmitted from the satellite to the designated recipient(s).

With a 30% success rate, it is not reliable. Had my wife realized the severity of the flood, she probably would have contacted emergency assistance since my messages were not coming through. IMO, it is a piece of junk unless this problem is resolved. Are other people experiencing this same problem?

Send problems on 11/22/2011 16:35:45 MST Print View

I've used mine ~100 times and had it fail to send maybe a half dozen, invariably when I was deep in a canyon or under dense forest. It does not give any indication of failure (in fact the opposite, it says it has sent successfully). My understanding is that the SOS feature sends a ton more messages than the Check-in/OK feature.

When I was using mine on the CDT, the deal with people at home was that missed Check-Ins should not be interpreted as "OMG HE IS DEAD". The Check-In is just a nice way to say hi to people at home. If the SOS was similarly flawed, that would make the device useless, but having never used it, I can't say whether that's the case.

Hi Gerry,

Yes, you are right, it pays to follow the instructions. If you want the OK to work reliably you do need to let the unit stay on for a while. If you do, you will find that the SPOT has near 100% reliability sending OK messages. If you don’t, you risk a low percentage of OK messages going out.

Note that the green light DOES NOT mean that it has successfully sent a message. Only that it is sending a message. You need to leave it on to be sure it actually hits a satellite when it is sending. Thus the 20 minute period and multiple attempts, to increase the probability that a satellite is in position when your SPOT unit sends. This is not a defect of the SPOT but the nature of satellite coverage. (At times, I’ve had a devil of a time getting Sat Phones to reliability connect in the backcountry.)

If you are constantly on the move then the best times to send an OK message are when first you get up in the morning and before leaving camp, during your lunch break, or just when you get in camp at night. There should be ample opportunity then to leave it on for 20 minutes or so. This is what I normally do, as I move a lot during the day.

Also, you do not need to stay in one place to use the SPOT OK. You can press the OK button and walk down the trail for 20 minutes. Assuming decent open sky, and that the SPOT is something approximating horizontal, it should work with reasonable reliability while you walk. (User trick. If you happen to be using track progress mode, you can activate that first, then press OK for a check-in. After the required 20 minutes, the SPOT will automatically go back to tracking progress mode. This is a great way to leave camp in the morning, or do a midday check-in.)

Finally the Globalstar satellite “problem” is a Sat Phone only problem due to amplifier failure on the band that supports Sat Phone signals. This does not affect the SPOT which uses a different band and electronics on the satellite. In fact, the SPOT was created to better utilize the satellites by using good working circuitry on them.

So the SPOT is not junk. But like most equipment, it requires some user knowledge, and it needs to be used properly and within its limitations.

Best of luck using the SPOT on your next trip!

SPOT messenger question on 11/22/2011 17:11:26 MST Print View

Responding to Gerry Brucia's question about reliability of sending SPOT OK messages.

First, as Ryley said, your agreed upon protocol with your home-base should be that an absence of messages can not be interpreted as a problem. "...protocol is this: If there are no tracks or SPOT2 messages, it does NOT mean that we have a problem. It could be one of many reasons, but you should NOT worry about it. (dead battery, device lost or damaged, etc). In this case revert to protocols used before we started carrying SPOT2: assume all is well until 24 hours after our expected trip completion time, at which point Responsible Party should notify the appropriate agency to initiate SAR."

A PLB is undoubtedly a more reliable device, and if you require that level of service, you might consider carrying both. Unfortunately, a PLB doesn't allow you to proactively tell your wife that things are AOK, which is what you were trying to do. A Sat phone allows the person in the field to know that the recipient got the message, which SPOT does not. However a Sat phone is not necessarily more reliable than a SPOT - the difference is that you know if the recipient got your message.

Second, you don't need to stand in one place for 20 minutes after initiating the OK, you can just leave the device on and continue walking or cycling or whatever you're doing. The device doesn't need to be still to work. To increase the likelihood of a message going through, you really should plan to leave the device on so that it transmits multiple times.

Third, I have had >90% transmission success for both Tracking and OK messages when using Lithium batteries, even when they are mostly drained and the battery light is red. On the other hand, partially drained Alkaline batteries give me a success of something between 10% and 50%. In other words, do everything you can to use Lithium batteries.

Fourth, I have now had two SPOT-2 devices COMPLETELY FAIL while on hiking trips, one in May2011 and the other in Oct2011. The GPS chip stopped working, and the devices were dead-weight. In both cases SPOT replaced the unit. However, this level of reliability is a huge problem. This is one reason I think it's critical that the home-base knows that an absence of messages does not necessarily mean there is a problem. I'm still a fan of the SPOT concept and functional design. However, the reliability problems I've had make me eager to see some other company offer a competitive product.

"This is not a defect of the SPOT but the nature of satellite coverage."

Actually, it is the nature of Globalstar satellite coverage, not satellites in general.

while im sure there are PLBs that are duds ... and that those dont get reported as much due to the "use only when shiet happens"

IMO this level of failure is not acceptable at all ... even if SPOT replaces the unit, if something happens on the trip, yr up the creek with no paddle ...
