Garmin GPSMAP 79s
This handheld is water-resistant IPX7 with a high-resolution colour display you can read in the sun. The glass is even scratch-resistant and fogproof.
DESIGNED TO FLOAT
If rough waters come and the handheld goes overboard, don’t worry. This device floats.
User-replaceable AA batteries (not included) provide up to 19 hours of battery life in GPS tracking mode.
With support for multiple satellite constellations — such as GPS, GLONASS, Beidou, Galileo, QZSS and SBAS — you’ll get accurate, reliable tracking and positioning around the world.
More memory than previous models means you can save and track 10,000 waypoints, 250 routes and 300 fitness activity files.
The 3-axis tilt-compensated electronic compass shows your heading — even while the boat is standing still.
