GPSMAP® 820xs w/DownVü Transducer
The GPSMAP 820xs keyed chartplotter/sonar combo has a 8-inch color SVGA display and comes preloaded with a worldwide basemap. HD-ID, CHIRP and DownVü with CHIRP sonar technology are built-in, allowing you the flexibility to choose from several optional transducers. It also provides media integration and autopilot compatibility, radar support, and NMEA 2000® and wireless connectivity.
Extreme Sonar Capabilities
The built-in sonar capabilities of the GPSMAP 820xs gives you the freedom and flexibility to choose from several optional transducers, including traditional, CHIRP and all-in-one HD-ID/DownVü scanning sonar with CHIRP technology. Add a GCV 10 scanning sonar module for both DownVü and SideVü scanning sonar with CHIRP technology (sold separately).
Allow networked combos to share their internal sonar with any other device on the network. GPSMAP 820xs also gives you the flexibility to choose what information is overlaid on the sonar screen. For example, time of day or GPS speed.
It also includes sonar-recording capability that coordinates the timing of the sonar return with your boat's position and saves digital information for playback on a computer using HomePort planning software.
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.
Dynamic Sea Temperature
Set a range for sea temperatures, and it dynamically adjusts to display a color range that can be used to target certain types of fish (Optional GXM 52 required).
Add your choice of marine radar, either open array or our new xHD dome radar that pair ease of use with advanced open array features.
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 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.
The GPSMAP 820xs offers select networking capabilities that allow you to share features with other compatible GPSMAP units, such as radar, GCV 10 DownV and SideV scanning sonar, supplemental maps, and user data, including waypoints, routes and tracks. User data entered into 1 chartplotter can be automatically synced with other chartplotters in a network.
Special Sailing Features
Supported sailing features include laylines, enhanced wind rose, heading and course-over-ground lines, true wind data fields and tide/current/time slider. Gauge displays are designed to provide important need-to-know information at a glance, including true and apparent wind angle, set and drift, true or apparent wind speed, horizontal or vertical graphs, and a data bar with customizable data fields.
View and Control Your Device from a Smartphone or Tablet
Garmin Helm allows you to view and control your compatible Garmin chartplotter from an iPhone® or iPad® or phone, or phone or tablet using Android - while providing enhanced situational awareness for the mariner. Easily switch betw
