My principal had a GPS in the Green Swamp a few years ago...there was tons of cloud cover so it didn't work.He was lost for 10 hours.

.I was a point man in the military and can uae a compass very well.. I print out maps off of google earth and shoot my asthmus right from my house. Yesterday at Three Lakes I couldn't find my trail tacks..very foggy ..I brought out the trusty 4.99 Walmart compass..and shot my asthmus at 320 degrees..spot on..

I love my compass..but .for my automobile..I love my GPS.
