These sleek 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 440-series is preloaded with highly-detailed BlueChart g2 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 440s and 440sx also offer split-screen viewing of map and sounder data for easy, continuous reference. The 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 - so you can spend more time enjoying the water and less time worrying about the weather. Plug in optional BlueChart g2 Vision cards to add true 3D-view detailed mapping capabilities (both above and below the waterline), plus helpful auto guidance, high-resolution photomapping detail, and "real picture" aerial photos of ports, harbors, marinas, waterways, navigation landmarks and other points of interest.
