Delorme InReach or Other??? on 01/10/2013 15:00:47 MST Print View

I have been trying to sort out the multiple “PLBs” on the market for the upcoming season and am looking for some real world experience. I don’t want to hash out what is a “real” PLB and what is not. I just want to hear peoples thoughts on the units that they have used. As far as my experience, I have been using a spot 1 for several years with no issues. I have always got the “OK” signal out to the family without failure on trips to CO, WY, and UT. The problem is that on longer trips I have always rented a SAT Phone so I could get in touch with the wife in case there was an emergency back home. In order to avoid this cost in the future, I was considering the Delorme In-Reach and pare it with my smart phone. While the subscription is pretty high, at least I would be able to avoid the sat phone rental at least once a year (about $100).

It seems that the Inreach would be the best option if I had to communicate with the family while on a trip. My other options are just to continue with the SPOT or get an ACR unit, and bite the bullet once a year for the sat phone. Even though the SPOT has worked very well for me so far, the multitude of horror stories with the SPOT has me worried.

So, Inreach users, what’s your thoughts?

I was a loyal SPOT user , all three different models, until the DeLorme inReach came out. I have been much happier so far with the features of the inReach. To me, it seems to be more advanced, technically speaking than even the latest SPOT. I have enjoyed the two-way texting feature of the DeLorme, and it has been very reliable. It has a more solid, sturdier housing too.

Can you use the in reach as a stand alone PLB if you do not purchase any subscription services?

I have a Spot GPS messenger (the smaller second revision), and I haven't used the Delorme or Spot connect. I made the choice to go with the Spot messenger because I didn't want one that paired with a smart phone. I've used the Spot for 2 years and I've never had it not get a message out and I am glad that I don't need my smart phone as part of the system.

I pay for the 'tracking' service for Spot, but rarely use it, my feeling is that I want to make sure that the batteries work should a real emergency situation arise, so I usually limit myself to check-in-ok in the mornings and evenings.

This year I plan on getting a 4 ounce (130 gram) ACR PLB ( to use in case of an emergency, and then use the Spot in tracking mode more often to leave "bread crumbs". Yes, this involves carrying both the Spot and an PLB, but they are both tiny and I feel that this gives a system that will both allow messages, real-time-tracking while providing a very robust way of getting the message out in an emergency.

For what it is worth - The devices break into three categories and depending on what you want to use it for you can figure it out from there. Not trying to open up the "what's a real PLB" question. Just trying to make sure everyone compares apples to apples. If anyone reads Practical Sailor magazine they do pretty good consumer report type reviews of EPIRBs, PLBs, One-Way messengers, and Two-Way messengers.

PLBs offer great safety and security, they do not require a service contract and are backed by government SAR professionals. This is the only option for emergency only type response. Lots of good ones out there to chose from, one advantage to PLBs is they all conform to strict standards.

One way messenger - ie SPOT. Lots has been said on this in the past so I wont repeat, It is what it is - a one way messaging device.

Two way messaging devices - Iridium has released a short burst data modem that has found its way into a bunch of new products. Each one offers some form of two way text messaging and emergency communications capability over the Iridium satellites. DeLorme Inreach is one, Yellowbrick 3 is another which is also based on the same Iridium modem (, the company I work for BriarTek also makes a device called Cerberus ( Some of the manufactures offer rental programs so if you are not ready to invest in a yearly contract but want to give it a try that is an option. Since I work for one of the companies I will not post any subjective thoughts - just the facts as I know them.

Thank you Joe. Very professional way to approach the question.

Last year I called around and tried to find someone willing to rent a Spot or InReach. No one would. I came across the Cyberlink a couple months ago and was really thrilled to see that you rent devices. This seems like a logical piece of equipment to rent for those of us not on the trail constantly (for me, 2 young kids, run an organization, working on one more degree).

If anyone else out in BPL-land has experience with these other devices, I am sure many of us would be curious. I already planned on renting a Cyberlink for my next big trip (wife insists on it) and can report back. Its less than half the price of renting a sat phone, and has to be more reliable (half my sat attempts at a sat phone call or text did not work).

PS: just to be clear, I have zero connection with Joe or his company. just trying to find a less expensive way to convince the wife to not freak out when I want to go solo.

Joe, is the weight of the Cyberlink listed on your website (186g or 6.6oz) with or without batteries? Is the battery removable or built-in/rechargeable?

If the weight is with batteries, then the weight of the device is appealing. It would not weigh much more than the Spot, but with greater functionality (e.g., 2 way msg).

I could take this line of questions off-forum and contact Joe's company directly, but I am assuming others here might be interested in the answers.

The Weight includes the internal rechargeable battery. The battery lasts for about a month in standby mode and can send around 1000 messages per charge. I won't make public comparisons between products since I clearly have a bias.

There is lots of new stuff coming out all the time (not just from us but from industry at large) If there are features or capabilities that people are interested in, make your voice heard. I know of lots of companies that are working on competing devices, the more people discuss what is useful and what is not the better all of these products will eventually become.

If anybody wants information offline you can reach me directly at I'm also happy to answer any questions here just want to make sure I don't violate good manners and/or policy.

Thanks again Joe. Very helpful and exiting to hear (I prefer internal rechargeable myself over replaceable batteries, but i am not thru-hiking these days).

Any exciting new technology developments you see coming...would love to hear.

Hi Joe, welcome to BPL!

Thanks for posting the info regarding the CyberLink and for being upfront about your affiliation.

I have to admit that I was not aware of your company or the devices mentioned in your post. It's nice to have additional options. Can you tell me what the difference is between the CyberLink and the Cyberus or are they the same thing and I'm just getting confused with branding?

I like that you have a rental program, that's a big bonus for the backpacking crowd.

I also notice that your business is largely focused on nautical applications so I was wondering if the testing of your devices ever focuses on dense cover reception? As a boater, I know that I have never had a problem getting a lock when on the water with any GPS enabled device I've used but under heavy tree cover it's another story. I'd be concerned about carrying one of your devices if it was designed solely for on water use.

I also found your service plans interesting. Quite different from my Spot and inReach agreements. How are your plans licensed outside of the USA (I'm in Canada)?

Since I've never seen a CyberLink (or Cyberus?) I can't really comment other than to say that for backwoods travel, I prefer replaceable batteries (either a replaceable battery pack like my camera or Lithium AA's would be even better (just a thought).

I will also say that if you want to jump ahead of the competition, add a display to your units that will allow me to read my current GPS coordinates. All of the manufacturers of these devices have GPS receivers on board but few allow you to view your current coords. Just a suggestion (and high value for backpackers).

Thanks for the feedback and suggestions. In addition to your post I've received several emails asking about foliage penetration so I figured I'd address that question here for all. Again, I'll stay away from specific product comparisons since I am a manufacturer I'll stick to the basic properties of the devices that impact signal quality.

To better address the concerns regarding signal reliability under dense tree cover we need to look at some basic differences between devices. To start with there is a significant difference between the new two-way messaging devices and PLBs in that PLBs operate on 406MHz and all of the Iridium based messengers (Including our Cerberus) operate on approximately 1.6GHz . As you go up in frequency your wavelength gets smaller. There are lots of implications to this but one of them is that the ability of a signal to penetrate goes down as wavelength goes down. (oversimplification but a general rule) As I stated in an earlier message, the new two-way messaging devices are not PLBs, if you are carrying a device as a "help, I've fallen and I can't get up" then a PLB is the best choice. Better penetration, better standards, known response from SAR authorities. The down side is they are only useful in an emergency and there is no way to let anybody know what you actually need (ie rescue vs, directions, vs. immediate medical attention vs. send a message to my wife I'v decided to stay out here for another week.) PLBs also can not be used to warn you of a hazard not let you know about an emergency back home.

The two-way texting devices on the Iridium network for the most part use the same (or similar) satellite modems. There are two types in production (9602 and 9603) they are very similar and both will yield the same foliage penetration. The antennas used by a particular manufacturer will make a difference but here again most of what I have seen indicates we are all using the same or similar antennas.

I'd love to get on this site and promise you all that these devices will work under any dense coverage and that mine is the best in that category but the truth is, it's a tough problem and in my opinion nobody has a clear and convincing hardware advantage. We are on the same satellite network, use the same (or similar) modems and use the same (or similar) antennas. We each have done some design work to optimize performance but we all have the same laws of physics.

One area where there is a very big difference is in the ability to understand when you do and do not have clear signal. Unlike cell phones and satellite phones these two-way messengers are not continuously in view of the satellites. They drop in and out of coverage as the satellites fly overhead. This can make determining if you are in a "good" spot pretty frustrating. In the case of Cerberus we have a "check signal" feature which allows you to see if you have a satellite in view. We also provide positive feedback that lets you know when a message has been sent or is pending.

Another difference is in how the units are programmed. For example, if I wanted to save battery life I could only transmit signal when a user hits a "send" button. The downside of this is that if the user hits that button when he/she is not in view of a satellite then the message will not go through. If instead I continue to transmit until I see a satellite you can imagine that I would burn through a battery pretty quickly if I am in a cave or other environment where I can't see the sky. Again each manufacturer deals with this tradeoff in a different way.

Last but not least I would caution you not to put all of your faith into "testing" on this subject. Weather and environmental conditions play a huge role. A system that works in a dense forest on a sunny day in January may fail miserably in an October rain storm. This is true for PLBs, SPOT, and two-way texting devices such as Cerberus.

Sorry for the very long post.

Some clarifications may be necessary here. For one thing, there are satellites and then there are satellites. Not all satellites are equal, not by a long shot.

Originally, there were communications satellites. These were normally all geostationary. That means that they were at an orbital altitude of about 22,000 miles and they appear to be hovering over the Equator. These work fine if you have an Earth station and you want to point it at one spot in the sky.

Then we got non-geostationary satellites. GPS (Navstar) satellites are good examples. They fly an inclined polar orbit at about 11,000 miles, so they appear to be moving across the sky. There are dozens of them, so it seems like a complete mesh of satellites in the sky from virtually anyplace on Earth.

At lower orbits, you have the LEO's (Low Earth Orbit satellite). They also appear to be coming and going overhead. Think Globalstar and Iridium satellites.

Different types of satellite use different frequencies, and that choice is governed by the different atmospheric layers and which layers reflect which frequencies. So, a Globalstar or Iridium satellite tends to want to receive an uplink frequency of about 1.62 GHz. In contrast, the international SAR satellites want to receive 406 MHz for an emergency signal.

That 1.62 GHz uplink is an interesting choice of frequency. It isn't too far from the GPS downlink frequency (1.57 GHz). The difference, of course, is that with a Globalstar or Iridium, you have the transmitter power on Earth pointed upward, and in GPS you have the (much higher) transmitter power in space pointed downward. But then, GPS "birds" are much higher, so there is much more distance to transmit.

With Globalstar and Iridium, they work by "bouncing" all uplink signals back to some Earth station on the Earth's surface. That works fine as long as they are close to land where the Earth stations are located. But that does not work when they are out over the middle of the ocean where there are no Earth stations. That is something to consider if you are a mariner at sea, but that is not an issue for a backpacker. Some of these LEO satellite networks are more complete than others, and that dictates some of the reliability of a single message getting through. In contrast, the international SAR satellites are up higher, so they tend to "see" emergency beacons more reliably.

The U.S. military specifically chose 1.57 GHz for the primary GPS downlink frequency because it works in all weather. You would not want a frequency that would fail during some foul-weather military mission. So, the nearby 1.62 GHz frequency should be almost the same. I don't think that you would want to try to transmit over your Iridium phone link when you are trying to get an accurate GPS position fix at the same time. High powered transmitters and low powered receivers don't mix, at least at the same frequency and the same instant of time.

That 1.57 or 1.62 can get mangled by overhead foliage, and that is especially true if the foliage is fresh and green (holding lots of water) or else if the foliage is dripping wet from rain or snow. If you think this is a factor, then move out into the open if possible.

Very helpful post Joe. Just starting to look into these devices.
