GPSMAP 76c

Product description from Garmin:

All other marine handheld GPS units pale when compared to the GPSMAP 76C and 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.

Both the GPSMAP 76C and GPSMAP 76CS have 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.

They’re 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).
