Garmin GPSMAP 840xs Chartplotter Fishfinder is especially useful for operators who want one display to manage navigation, waypoint work, and sonar interpretation without moving between separate devices. Internal 10 Hz GPS/GLONASS; NMEA 2000, NMEA 0183, Marine Network.
Key Features
- Display clarity: Uses an 8-inch VGA display with 800 x 600 Pixels so sonar, charts, and system data remain easier to read from the helm.
- Sonar capability: Built-in CHIRP and DownVü Scanning. Adds a tighter view below the hull for reading structure, edges, and bottom changes.
- Positioning: Internal 10 Hz GPS/GLONASS keeps chart position and waypoint updates responsive for navigation and return-to-spot accuracy.
- System integration: NMEA 2000, NMEA 0183, Marine Network allows the unit to share data with compatible marine electronics and sensors.
- Wireless support: Wi-Fi (BlueChart Mobile and Garmin Helm) expands access to compatible mobile or remote helm functions where supported.
- Mounting options: Options such as Bail, Flush, or Flat-Mount make it easier to match the installation to the console layout.
Applications
This combo unit is a practical fit for boats that need charting and sonar together on one screen without adding separate helm displays. It suits everyday navigation, fishing, and route management on inland and coastal waters where quick access to charts, waypoints, and sonar returns helps with on-water decisions.
The display size and built-in GPS mapping also make it easier to run split-screen views so operators can watch position, bottom changes, and fish targets at the same time.
