The GPSMAP 420s 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 420s also has an SD™ card slot so you can add additional features with the optional BlueChart® g2 Vision card.
The GPSMAP 420s sounder version 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 420s is also CANet™ compatible, so you can share sounder data with another chartplotter on your boat.
