Our Comment

The Colorado 300 comes with a high-sensitivity GPS receiver and shaded-relief and satellite imagery mapping.  The vibrant colour 3" screen with high resolution is completely visible whether you are in low light areas or you've got the sun shining behind you.

A great new feature on this handheld mapping system is the Wireless capability that allows you to share your waypoints, tracks, routes and geocaches wirelessly with other Colorado users.
