This H2Oproof FRS/GMRS radio plus GPS navigator has a built-in barometric altimeter and electronic compass, NOAA weather radio, voice scrambler and vibrate mode for your wildest outdoor adventures. Rino 130's barometric altimeter pinpoints your precise altitude, and its built-in electronic compass provides bearing information even while you're standing still. To help you keep tabs on changing weather conditions, Rino 130 has a built-in weather radio that scans for the nearest NOAA weather radio station. You can also set up a weather alert tone, so when your radio is on, it will alert you when a storm warning is being broadcast for your area.
