Garmin Etrex, 100 bucks. It's a very basic GPS, no uploadable maps, none of that.....But.....you'll be able to find your way home. Pull up the waypoint you want to go to, select it, and a great big arrow pops up on the screen. Keep the arrow pointed in front of you, you'll walk right into it.
They're pretty cool, especially for as basic as they are.
I agree. Believe it or not the basic Etrex is what I used in Colorado in the Flat Tops Wilderness. Without it I would have been in bad shape and it allowed me to venture off in any direction with confidence. It worked great and is simple and easy to learn to use.
