Garmin GPSMAP520 Chartplotter/Fishfinder - DISCONTINUED PRODUCT, CALL FOR PRICING & AVAILABILITY This slim-line chartplotter flush-mounts easily in your boat and boasts an ultra-bright 5" QVGA display. The GPSMAP 520 also sports a built-in, satellite-enhanced worldwide basemap and simple, straightforward buttons and menus. You can add the optional BlueChart® g2 Vision SD card for even more enhanced features. Navigate with Ease With just a few buttons and a simple, intuitive interface, the GPSMAP 520 makes navigating virtually effortless. And instead of a traditional basemap, the 520 has a basemap of worldwide satellite images. It also has an SD card slot so you can add additional detailed maps without connecting to a computer. Add Sonar Where applicable, the sounder version, GPSMAP 520s , comes with a powerful dual frequency transducer that clearly paints depth contours, fish targets and structure whether you're fishing in freshwater or off the coast. The 520 and 520s are also CANet™ compatible, so you can share sounder data with another chartplotter on your boat. Add Extras with BlueChart g2 Vision With the optional BlueChart g2 Vision SD card, you can add a whole new dimension of exceptional features to your chartplotter. 3D mariner's eye view or fish eye view provides you with a 3-dimensional perspective of map information, both above the waterline and below it. High-resolution satellite images and aerial photographs help you orient yourself in unfamiliar areas. Auto Guidance technology searches through all relevant charts to create a route you can actually follow - one that avoids obstacles, shallow water, buoys and other obstructions.
