GPSMAP 78s comes with built-in worldwide basemap, so you can navigate anywhere with ease. And, like the rest of the 78-series, 78s is IPX7 waterproof and even floats in water.

Get Your Bearings
GPSMAP 78s 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 to keep an eye on changing weather conditions.

Share Wirelessly
With GPSMAP 78s you can share your waypoints, tracks, routes and geocaches wirelessly with other compatible device users. Now you can send the location of your favourite 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 78s locates your position quickly and precisely and maintains its GPS location even in heavy cover and built-up areas. The advantage is clear — whether you’re in dense woods or just near tall buildings and trees, you can count on GPSMAP 78s to help you find your way when you need it the most.

Add Maps
Adding more maps is easy with Garmin's 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 by road (see maps tab for compatible maps). The card slot is located inside the waterproof battery compartment, so you don't have to worry about getting it wet. GPSMAP 78 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 78s is compatible with Custom Maps, free Garmin software that transforms your own paper and electronic maps into downloadable maps for your GPS handheld device.
