I use mine quite a bit to mark access points, and sometimes decent spots on the water. It's an older Garmin etrex Venture, doesn't have much in the way of features. Its small and pretty water resistant, we used 2 identical ones when we did the Mackenzie river last year with no issues (one for backup) Didn't really need them to find our way, but to roughly calculate a distance to the next town, etc, or to be able to give a location in case of an emergency. I do believe some of the newer ones have a different antenna that picks up signal better in overhead cover, Lorney's does I'm pretty sure, and a built in 2 way. I'm not really up to date on new technology or features, but as was said about bear spray, good to have for sure. My memory can be great or terrible, so I mark waypoints just in case, mostly for future reference.
