The GPSMAP 840xs keyed chartplotter/sonar combo has a 8" color SVGA display and comes with preloaded U.S. LakeVu HD and BlueChart g2 coastal maps. HD-ID 1 kW sonar, CHIRP and DownVu with CHIRP sonar technology are built-in allowing you the flexibility to choose from several optional transducers.
Extreme Sonar Capabilities
The built-in sonar capabilities of the GPSMAP 840xs gives you the freedom and flexibility to choose from several optional transducers, including 1 kW traditional, CHIRP and all-in-one HD-ID/DownVu scanning sonar with CHIRP technology. Add a GCV 10 black box sonar for both DownVu and SideVu scanning sonar with CHIRP technology (sold separately).
When used with a compatible CHIRP transducer (sold separately), GPSMAP 840xs 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.
Includes Inland and Coastal Mapping
The GPSMAP 840xs comes preloaded with both BlueChart g2 coastal maps and LakeVü HD, which features 17,000 U.S. lakes, of which more than 5,700 HD lakes have 1' contours shoreline to shoreline. It's also compatible with optional mapping, LakeVu HD Ultra with MaxDef Lakes and BlueChart g2 Vision.
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.
The GPSMAP 840xs offers select networking capabilities that allow you to share features with other compatible GPSMAP units, such as radar, GCV 10 DownVu and SideVu scanning sonar, supplemental maps, and user data, such as waypoints, routes and tracks.
