The GPSMAP 420 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 420 also has an SD card slot so you can add additional features with the optional BlueChart?? g2 Vision card.

View Satellite-enhanced Maps

The 420??s 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 420 makes navigating your way through the water easy.

Add Sonar

Where applicable, the sounder version, GPSMAP 420s, 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 420 and 420s 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.
