Last year a buddy of mine and I were hunting a 2500 acre piece of Game Management property and got turned around in the darkness and ended up spending 2.5 extra hours getting out of those woods. We were walking parallel with the dag gum road but never knew it. Both of us had GPS's but left them in the truck with both of our phones. Very Bright. If I had been by myself I may have freaked out but having someone to talk to helped.
