For boaters and watersports enthusiasts who want to run with the best, the rugged GPSMAP 78 features crisp color mapping, high-sensitivity receiver, new molded rubber side grips, plus a microSD card slot for loading additional maps. And it floats! Garmin’s GPSMAP 78 comes with a built-in worldwide basemap, so you can navigate anywhere with ease. And, like the rest of the 78-series, the 78 is water resistant (IPX7) and even floats in water. With its high-sensitivity, WAAS-enabled GPS receiver and HotFix satellite prediction, GPSMAP 78 locates your position quickly and precisely and maintains its GPS location even in heavy cover and deep canyons. 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. The card slot is located inside the water resistant 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. With a simple connection to your computer and to the Internet, you can get a detailed analysis of your activities and send tracks to your outdoor device using Garmin Connect. GPSMAP 78 supports geocaching GPX files for downloading geocaches and details straight to your unit. What’s in the box: GPSMAP 78, wrist strap, USB cable and Quickstart Guide.
