ExpertGPS is GPS map software for your Windows computer or laptop. ExpertGPS makes it easy to transfer waypoints, routes, and tracks, as well as GPS, GIS, and CAD data, to and from your Garmin Lowrance HDS GPS chartplotter.
ExpertGPS gives you unlimited, FREE access to every topo map in the USA, as well as high-resolution aerial photos, so you can zoom in on any trail or job site. ExpertGPS even works with your own scanned maps, and data from over 100 different mapping, GIS, and CAD programs.

If you have a new GPS that isn't on this list yet, it's almost certainly guaranteed to work in ExpertGPS. Select the closest match in ExpertGPS, or send us an email and we'll add it to this list!
