All other marine handheld GPS units will pale when compared to the GPSMAP 76CS - literally.
The latest color-display technology gives both units the brightest, sunlight-readable displays available. And with brand-new state-of-the-art receivers and powerful microprocessors, these units will give you a quick and steady fix. In addition, the GPSMAP 76CS boasts a built-in electronic compass and barometric altimeter.
The GPSMAP 76CS has the familiar GPS 76-family keypads and styling, with 115 MB of memory, an Americas Autoroute basemap, and a Marine Point database. Fast USB connectivity makes loading charts and maps quick and easy, while navigation instructions can be shared with repeaters, plotters, and autopilots using NMEA protocols through the dedicated serial port.
It's waterproof and fully compatible with MapSource products like BlueChart, U.S. Topo 24K, and City Select (which provides detailed streets for turn-by-turn guidance).
