Explore Coastal Waters

Map detail includes shorelines, depth contours, navaids, harbors, marinas and more for the U.S. and Bahamas.

Get Your Bearings
GPSMAP 78sc has a built-in 3-axis tilt-compensated electronic compass, which shows your heading even when you’re standing still, without holding it level. Its barometric altimeter tracks changes in pressure to pinpoint your precise altitude, and you can even use it to plot barometric pressure over time, which can help you keep an eye on changing weather conditions.
With GPSMAP 78sc you can share your waypoints, tracks, routes and geocaches wirelessly with other compatible device users. Now you can send the location of your favorite fishing spot to a friend to find. Sharing data is easy. Just press “send” to transfer your information to similar units.
Keep Your Fix
With its high-sensitivity, WAAS-enabled GPS receiver and HotFix™ satellite prediction, GPSMAP 78sc locates your position quickly and precisely and maintains its GPS location even in heavy cover and deep canyons. The advantage is clear — whether you’re in deep woods or just near tall buildings and trees, you can count on GPSMAP 78sc to help you find your way when you need it the most.
Adding more maps is easy with our wide array of detailed marine, topographic and road maps, available on microSD card. Conveniently plug in BlueChart® g2 preloaded cards for a great day on the water or City Navigator NT® map data for turn-by-turn routing on roads (see maps tab for compatible maps). The card slot is located inside the water resistant battery compartment, so you don’t have to worry about getting it wet. GPSMAP 78sc also supports BirdsEye™ Satellite Imagery (subscription required), that lets you download satellite images to your device and integrate them with your maps. In addition, the 78sc is compatible with Custom Maps, free software that transforms paper and electronic maps into downloadable maps for your device.
