Manufacturer Description

Offshore fishermen and boaters will gravitate toward this sleek, space-saving chartplotter. The GPSMAP 440 features preloaded detailed maps for the U.S. coast as well as an ultra-bright 4” QVGA display; built-in, satellite-enhanced worldwide basemap and simplified user operation.

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 a nd 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.
