I have a Garmin 60CSX. It works great! I also believe you art talking about maps from www.huntinggpsmaps.com? If so you have found yourself a great map! I have the map they offer for a few states including MT. It shows all BLM land, State lands, National Forests, private lands and their land owners names, etc, etc. The MT map has really opened up my opportunities for accessing hunting land in MT, both private and public. Definately worth looking into. Good luck on your hunt for GPS/Maps/Elk
