8" Keyed Chartplotter/Sonar Combo for Cruising, Sailing or Fishing
Keyed chartplotter/sonar combo with 8” color SVGA display
Preloaded worldwide basemap
Built-in Garmin HD-ID™ 1 kW sonar, CHIRP and DownVü™ scanning sonar with CHIRP technology
High-sensitivity internal 10 Hz GPS/GLONASS receiver
Supports all Garmin marine radar
The GPSMAP 820xs keyed chartplotter/sonar combo has a 8” color SVGA display and comes preloaded with a worldwide basemap. HD-ID 1 kW sonar, CHIRP and DownVü with CHIRP sonar technology are built-in allowing you the flexibility to choose from several optional transducers.
When used with a compatible CHIRP transducer (sold separately), GPSMAP 820xs displays crystal-clear sonar images detailing fishing hot spots, ship wreckage or a diving location. With Garmin CHIRP technology, you get remarkable target separation and resolution at extraordinary depths, and can dial into specific frequencies to target certain species of sport fish. Bottom contours are more visible, even at speed, and signal noise can be suppressed at greater depths to provide a more timely interpretation of what’s below for safer navigation and better fishing.
Super-fast 10 Hz GPS/GLONASS
High-sensitivity internal 10 Hz GPS/GLONASS provides position and heading updates 10 times per second. It displays fluid on-screen location and proves to be incredibly accurate when marking 5,000 waypoints and navigating.
NMEA 2000 Support
This combo allows you to add more capabilities to your boat. It provides NMEA 2000 support so you can see valuable information on your screen for Garmin autopilot, engine data, SiriusXM® Weather radar and more.
Networking
The GPSMAP 820xs offers select networking capabilities that allow you to share features with other compatible GPSMAP units, such as radar, GCV 10 DownVü and SideVü scanning sonar, supplemental maps, and user data, such as waypoints, routes and tracks.
Special Sailing Features
Supported sailing features include laylines, enhanced wind rose, heading and course-over-ground lines, and true wind data fields.
