Get Your Bearings

GPSMAP 78s has a built-in 3-axis tilt-compensated electronic compass, which shows your heading even when youre 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.

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 deep canyons. The advantage is clear - whether youre in the deep woods or just near tall buildings and trees, you can count on the GPSMAP 78s to help 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 on roads. It 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, a free software that transforms paper and electronic maps into downloadable maps for your device.

It also stores and displays key information, including location, terrain, difficulty, hints and descriptions, which means no more manually entering coordinates and paper printouts.
