GPS Map 540S GPS/Sounder w/Built-In Blue Chart Pre-Loaded U.S. Coastal Areas Data - Features a 5" QVGA Display and Straightforward Buttons and Menus!

With an easier-to-use interface and sleek new design, the 540-series pack more value for your navigation dollar. They feature bright 5" QVGA color 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 540- 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 builtin analog sounder found in the 540s can scan as deep as 1500' (in dual frequency mode) and features UltraScroll for high-speed screen updates. The 540s also offers split-screen viewing of map and sounder data for easy, continuous reference. See real-time weather displayed on the 540-series' highresolution, sunlight readable display with the purchase of the GXM 31 antenna (sold separately) and subscription to XM WX Satellite Weather. View vital weather data such as NEXRAD radar, storm cells, wind speeds, surface temperatures, forecasts and more than a dozen other weather attributes directly on the unit's 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.
