Garmin GPSMap 420/ 420s

Discontinued. Has been replaced by the GPSMAP 421/421s

Sleek chartplotter offers big capability in a small package...
The Garmin GPSMap 420/420s features an ultra-bright 4" QVGA display, built-in worldwide satellite imagery and a new streamlined user interface. The 420s includes a combo sounder that can scan as deep as 1500 feet/ 457 meters (with dual frequency transducer) to clearly paint depth contours, fish targets, structure, etc. Both models are CANetT capable, allowing sounder data to be shared with other plotter displays.

BlueChart g2 Vision

All the new Garmin chartplotters feature basic worldwide satellite imagery for a realistic "view from space" depiction. With optional g2 Vision cards, these images are upgraded to super high-detail aerial photomapping. It's the most realistic map you've ever seen on a graphical chartplotter. And you can navigate 'on the picture' with a clear dynamic presentation of your boat's current position.

Auto Guidance. The optional Auto Guidance technology, unlocked via g2 Vision card, searches chart contents to suggest the safest known charted route for navigation.

True 3D-view mapping. Garmin's newest chartplotters wil graphically depict true 3D "mariner's eye" topside view or "fish eye" underwater view navigation perspective for tricky shoals, reefs, bridges, channels etc.

"Real Picture" Photo Reference. Aerial photography gives mariners a realistic visual overview of harbours, marinas, waterways and other points of reference. The photos allow a visual reference for nearby fuel pumps, dining spots, lodging and shore-side facilities. Also included is City Navigator North America NT road data for navigation up to five miles inland.

NOTE: XM Weather/ Traffic service not available in Canada; XM Radio is available.
