GPSMAP 78 comes with built-in worldwide basemap, so you can navigate anywhere with ease. And, like the rest of the 78-series, the 78 is IPX7 waterproof and
even floats in water.
Comes complete with Garmin's Bluechart G2 marine chart covering the whole of the UK & Ireland.
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 78 is
compatible with Custom Maps, free Garmin software that transforms your own paper and electronic maps into downloadable maps for your GPS handheld device.
