Orienteering was a required merit badge for me to get my Eagle Scout. I know exactly how to use a compass and a map, but with my Garmin GPS V, why would I want to. If I were to teach a class on using a GPS, I would start out using a compass, and then show the functionality of the GPS. I've been working on a project to teach how the gps functions. My mother has been thinking of having me show the girls in her church group about using a gps. I'm planning on gearing the class for teens and pre-teens. I would really be impressed if they were using sextants for their navagation. Come to think about it, I would consider paying $75 for a class on using sextants. But for doing my road/off road navagation, pry my GPS from my cold dead hands. Jake - Team A.I.
