The GPSMAP 76S has a built-in electronic compass that provides bearing information even while you're standing still, and its barometric altimeter tracks changes in pressure to pinpoint your precise altitude. You can even use the altimeter to plot barometric or ambient pressure over time, which can help you keep an eye on changing weather conditions.

Don't worry about losing this GPS device in the drink. Like the rest of the 76-series, the 76S floats in water, and it's IPX7 waterproof to withstand the accidental dunk or splash in the lake. Whether on water or land, the 76S can save up to 1000 of your favorite places in memory and can take you directly to your destination.

The GPSMAP 76S is preloaded with a basemap of principle cities, interstates (including exits), highways and roads as well as marine navigation aids, including lights, buoys, sound signals and day beacons. It also has 24 MB of internal memory, so you can load detailed maps from a variety of optional MapSource® products. If you're into boating, hunting or fishing, you can use the built-in celestial data, which includes tide information, sunrise/sunset times and a hunting and fishing calendar.
