got one of the more expensive ones. can map out a trail at the house, turn it on at the trailhead and if you get off just a few feet, it goes eep eep eep until you get back on. does lots of tricks, but, i carry a map and compas in another pocket. voices in my head say dont trust anything electronic and this puter proves that weekly. i can stagger around a puter problem, but have never seen the guts of a gps and could only be puzzled by it.
get the gps. carry map and compas JIC. i plan to get an inexpensive one when this one craps out. don't need all those bells and whistles. i use mine mostly for fishing on big lakes. mark spots and can retrack in the dark. is a super good tool to have and use. wife uses mine for bowhunting. says brings her almost exactly back to the truck. further says can spend more time watching for things than worrying about directions. am considering a pair of those that pinpoint the other's position. highly recommend gps.
