Garmin GPSMAP 498C Sounder Discontinued

The GPSMAP 498 Sounder includes dual frequency, full-featured sonar and built-in marine detail charts of the United States coastline, including Alaska and Hawaii - utilizing elements of Garmin's new BlueChart g2 technology. These charts provide integrated maps for a much smoother presentation. BlueChart g2 has all the detail of traditional BlueChart, but with 3D perspective, and richer detail and content - data like tides and currents overlaid on the chart. Other chart features include shaded depth contours, port plans, wrecks, restricted areas, and more. The GPSMAP 498 can also be supplemented with BlueChart g2 preprogrammed data cards providing extremely detailed marine charts, including highly detailed roads, points of interest, high quality color photos for the U.S ports, marinas, and more. And the GPSMAP 498C's built-in 500-watt (RMS) sounder features UltrascrollT for high-speed screen updates, with the proprietary Garmin CANetT bus enabling sounder display information to be shared with, and controlled from, another chartplotter on your boat.
