I've got delorme east coast version and have library of maps, topo and areils. But does anyone know what to look for or how to read one. I've long hiked the AT (App. Trail) from MD to Baxter State Park, ME and I'm presently training my 10 yr old son to use a map, compass, and gps. I bought him the same one I have. After researching to teach him, I'd bet most don't know how to accurately use a map. let alone a gps or compass. By a map, a good silva compass, and a simple gps. I say simple because, when i bought mine I bought 5 of the major brands at 1 time kept the reciept and took them home for the weekend and played with them. I kept the one that was simplest.The one I wouldn't have to carry the user's guide with. The garmin e-trex. Very simple and accurate enough for me. When I hiked the AT I had no gps nor did Lewis and Clark. A good map and comp [no swearing please] are all I really need. Teach yourself this skill and journey forth. My 10 yr old has know idea that he is in training for the rest of my life. Just like I'm with my grandfather. He raised me in the outdoors and life. He's 80 in good shape (rabbit hunted 2 times with me this year)and has seen so much. A great teacher. So much knowledge. To keep information in ones head without teaching is such a waste.
