Garmin GPSMAP fish finders use state of the art GPS technology to help you navigate the ever-changing marine landscape and find schools of fish at the same time. Ranging from the small GPSMAP 76CSx to the full-featured GPSMAP 720, these fish finders do for waterways what the Garmin nuvi series did for highways. Garmin GPSMAP chart plotters come pre-loaded with satellite-augmented basemaps, and most of them allow you to download additional maps as well. Garmin has outfitted some of these fishfinders with integrated radar capabilities and fully functional touchscreens, allowing you to plot a course easily without navigating your way through a sea of menus. Garmin fishfinders like these use highly accurate Garmin GPS technology to pinpoint your ship's location and analyze incoming weather patterns. Some devices in the Garmin GPSMAP series were designed to help you navigate the world's lakes, while other, larger models allow you to chart a course through the oceans with nothing but a touch of the screen. For state of the art fish finding and chart plotting, equip your vessel with a Garmin GPSMAP fishfinder.
