I bought DW one for Christmas (scored a good deal). You can mark 3 different location with a push of a button or 2. When you get ready to return to a marked location, turn it on and select the location. It guides you back with a "compass like " look. The screen shows you the direction back with an arrow and an estimated distance. No "bread crumb" trail. It's easy tou use and gets you back to your car in a big parking lot. It would get you back to a starting location in a big city or large oudoor area, but no map. It's better than getting real lost, but many cell phones with GPS capability are probably better if you marked your starting location and only one toy to carry.
