Chart the High Seas

The 440 has preloaded detailed maps that cover all U.S. coastal areas, including Alaska and Hawaii. For areas outside the U.S., the 440 has a worldwide basemap with 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 440 makes navigating your way through the water easy.

Add Sonar and Weather

Where applicable, the sounder version, GPSMAP 440s, comes with a powerful dual frequency transducer that clearly paints depth contours, fish targets and structure. It’s also CANet™ compatible, so you can share sounder data with another chartplotter on your boat. The weather-enabled versions, GPSMAP 440x and 440sx, display XM satellite weather data, including NEXRAD radar, with the GXM 31 antenna.

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.
