Took my InReach SE on a two-week road trip with occasional day hikes. Left it turned on all the time with 10 minute tracking, didn't send or receive any messages. The InReach was in a pack pocket under my fiberglass truck shell most of the time. Basically, I turned on tracking and forgot about it except for occasional status checks.
Battery charge lasted about 4-5 days.
- When the InReach SE detects no movement for a while, it automatically stops sending tracking points until you start moving again. I don't see any settings to affect this behavior.
- Somehow I found it too easy to accidentally turn OFF tracking repeatedly. Not sure how I did that, since you need to confirm by moving to a non-default selection.
- Charges OK from my truck's "accessory port" (aka cigarette lighter port), using a USB charger designed for iPhones, plus the InReach cable. Hooray for standardizing on USB charging!
- Tracked pretty well on day hikes under forest cover at 7,000 to 10,000 feet elevation at Grand Canyon NP (North Rim) and Great Basin NP, and on a bike ride through forests along the west short of Lake Tahoe.
- Also tracked well at highway speeds on various two-lane roads and Interstate highways.
- Missed a few points while wandering around cliff dwellings at Mesa Verde. With rock overhangs blocking most of the sky, not surprised.
- explore.delorme.com maps work OK on an iPad, but you need a fast Internet connection. BTW, Verizon has much better coverage than AT&T in remote parts of Arizona, New Mexico, Colorado, Utah and Nevada, but even Verizon has curious dead zones.
- I still think the cover for the USB port is too hard to put back on straight. But I'm sort of getting the hang of it.
Overall, I still like the InReach SE. Itching to take it into real wilderness.
