GARMIN GPSMAP 421 CHARTPLOTTER GPS NAVIGATION - WARRANTY


Works perfectly, fully tested with guarantee.


Including the sun cover, power/data cable and mount!


******

The GPSMAP 421 is a sleek, space-saving chartplotter that features an ultra-bright 4” QVGA display; built-in, satellite-enhanced worldwide basemap and simplified user operation. The 421 also has an SD™ card slot so you can add additional features with the optional BlueChart® g2 Vision card.


View Satellite-enhanced Maps

The 421 basemap contains worldwide satellite images in place of more traditional maps, and its SD card slot makes it easy to add additional maps without connecting to a computer. With fewer keys and a simple, intuitive interface, the 421s makes navigating your way through the water easy.


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.


MarinerEye view and FishEye view provide you a 3-dimensional perspective of map information, both above and below the waterline.

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.

For a low cost option try BlueChart g2 cards.
