use the topo map all the time with compass and gps. by using the gps, i can locate and mark many things on the map, e.g. beaver dams, scrapes, rubs, trails, tree stand sites, etc. by using a radio along with the map, i can locate where my hunting partners are located also. great tools and i never leave home without them. oh, one time i had left my camera in the woods near a ground stand, i still had the position in my gps, called my brother and gave him the position, he found the camera. i was in virginia and the camera was left in upstate new york, two miles back in the woods, yea, i would say they are great items to learn how to use.
