If you're a devoted mariner or serious outdoor enthusiast, the Garmin GPSMAP 76S is the GPS/mapping unit for you. The "S" in the product name stands for "sensors," referring to the GPS receiver, barometric altimeter, and electronic compass the GPSMAP 76S incorporates to deliver precise location, elevation, and bearing information. The unit also contains a basemap of North and South America, including major highways, thoroughfares, rivers, lakes, and borders, with plenty of memory (24 MB) for downloading MapSource data. It's also waterproof and floats in water--and its larger screen, increased readability, bigger buttons, and rugged design make this unit at home in even the harshest conditions.
