The GPSMAP 76S adds a built-in electronic compass and barometric altimeter, an Americas, European or Pacific basemap and 24 megabytes (MB) of map storage space to the other outstanding features of the mariner-friendly 76-series navigators. 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.
