GPSMAP 420/420S

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 boat computer. With fewer keys and a simple, intuitive interface, the 420 makes navigating your way through the water easy.

Add Marine sonar
Where applicable, the sounder version, GPSMAP 420s, comes with a powerful dual frequency transducer that clearly marine paints depth contours, fish targets and structure whether you're sailboat 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.
