The device allows you to plan your trips, retrieve information on trails, and organize your waypoints and trails. It’s preloaded with a world-wide basecamp with shaded topography, 250,000 geocaches, and 100,000 maps from TOPO U.S. The midrange model of the GPSMAP 64s is a consistent and reliable pick and sports a 2.6” display screen that is easy to read in bright sunlight and has 160 x 240 resolution. Expect to see a lot of Garmin - the brand dominates the field of handheld GPS devices.
