I am still using my Garmin e-Trex Legend for hunting and trail riding- it must be 5 or 6 years old by now.
Sometimes I’ll track a whole ride, sometimes I’ll just mark where the trailers are. Where I ride there generally is not cell service.
Sometimes I just mark the trailer or camp location and turn it off unless I need it. Either way, I carry spare batteries just in case.
When riding in a lot of places in these parts, if someone is injured in a remote area, a helicopter will only come if you can provide the GPS coordinates. Of course sometimes that means you might have to mark those and then ride to wherever you might find cell phone coverage, but that’s still better than some alternatives if medical attention is needed.
Mine isn’t wearable, so sometimes I loop it around my neck, sometimes on saddle, sometimes in pocket, depending. It will lose satellites in woods or some tight canyons but finds itself when you emerge.
Now I am thinking of an amusing tale- when hunting in Montana a group of four declared they were going in, and headed the wrong way. I politely observed that they were going in the wrong direction, the trailers were ‘thataway.’ They didn’t believe me, after all I was as new to the neighborhood as they were, so I pulled out the GPS and showed 'em. They STILL went off in the wrong direction.
Long story short, we finished our lovely day of hunting and they were NOT back at the trailers before we were. In fact they got rather panicked, tied horses up somewhere along the way and begged a passing vehicle to get them back to the trailers.
