GARMIN GPSMap 440 Series

The Garmin GPSMAP 440 series has been replaced with the Garmin GPSMAP 441 series.

Big capability chartplotter in a sleek, small package...
The Garmin GPSMAP 440 series Garmin plotters pack a lot of value into their space-saving formats. They feature ultra-bright 4" QVGA displays and come ready to launch right out of the box with built-in cartography, new worldwide satellite imagery and a new streamlined user interface. The GPSMAP 440 series is preloaded with highly-detailed BlueChart marine cartography of the coastal United States – including Alaska, Hawaii and the Bahamas. This data provides detailed coastlines, shaded depth contours, navaids, port plans, wrecks, restricted areas and tide and current information. The powerful built-in analog sounder found in the 440s and 440sx can scan as deep as 1500' (in dual frequency mode) and features UltraScroll for high-speed screen updates. The GPSMap 440s and 440sx also offer split-screen viewing of map and sounder data for easy, continuous reference.

The Garmin GPSMap 440x and 440sx come with the GXM 31 Smart Antenna. With a subscription to XM Satellite Weather, the 440x and 440sx can provide continuously-delivered weather on the unit's high-resolution sunlight-readable display. Vital weather data, such as NEXRAD radar, forecasts, and current conditions is graphically displayed directly on the chart.
XM . XM Weather/ Traffic service is not currently available in Canada. However, XM Radio is available. With a subscription to XM Satellite Radio, users will receive 160 digital channels of commercial-free music including more than 30 channels of news, sports, talk and entertainment along with 20 dedicated channels of XM Instant Traffic & Weather. It also features the deepest playlist in the industry with access to over 2 million titles.

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.
