I'm always amazed at the 'deep woods/remote location' rescues. Have a cell phone to call but don't use the GPS to relay location. Years ago, it was required to have a sat phone/gps receiver to get into remote Havasu canyon area. Of course the civilian system won't put you to 50 yds but it's better than a compass. Then there is the mil. survivor's flashlite/blinker. Probably some kid's toy with an LED 5 second blinker - just have to remember to take fresh batteries. I should talk, saw 3 deer and didn't even take my cellphone/camera with me.
