Product Information

Cellphones are notoriously unreliable, so what’s your navigational backup plan in case your electronics go down? What if you’re hopping on a small boat that doesn’t have electronics in the first place? Or you’re getting on a friend’s boat? There’s no good substitute for a handheld GPS you can carry every time you step aboard any boat, and the GPSMap 79s and 79sc are the next generation of handhelds. These units have high-resolution color displays; BaseMap or BlueChart g3 coastal charts; 8GB of memory; and can tap into GPS, Glonass, Galileo, the Quasi-Zenith Satellite System and satellite-based augmentation systems. What’s more, they’re waterproofed to IPX7 specs—and they even float.
