I agree with that. I turn mine on only at rest stops, take a reading, set a waypoint, and turn it back off. If something bad happens, I can use it to backtrack. Otherwise, I just follow the map.

I also find that it I try to leave it on it distracts me from the very important business of enjoying a nice walk in the woods.
