Garmin echoMAP™ 42dv


Great Combo Features for the Money

  • High-contrast colour display with keypad control with preloaded worldwide basemap
  • Built-in DownVü scanning sonar with the clearest images on the water¹
  • Built-in 500 W (RMS) HD-ID™ sonar (4,000 W peak-to-peak)
  • 5 Hz Internal GPS updates position and heading 5 times per second
  • Tilt/swivel quick-disconnect mount

echoMAP 42dv includes a 4.3-inch high-contrast colour display with automatic backlight adjustment. Fast, responsive 5 Hz GPS/GLONASS refreshes your position and heading 5 times each second to make your movement on the screen more fluid. echoMAP 42dv comeswith a GT20-TM transducer for 77/200 kHz HD-ID sonar and Garmin DownVü™, the clearest scanning sonar on the water (echoMAP 42dv is also available without transducer). It also supports Minn Kota® and MotorGuide® trolling motors with integrated transducers. The combo's cords plug directly into the mount, allowing you to quickly install and remove your device from power and the mount. Transom and trolling motor mount included.

Clearest Scanning Sonar on the Water

Garmin DownVü™ scanning sonar gives you a nearly photographic image down to 230 meters below your boat.  You clearly see structure, submerged objects and fish! Traditional Garmin HD-ID sonar and DownVü scanning sonar are combined into one transducer. Also provides HD-ID support for Minn Kota and MotorGuide trolling motors with integrated transducers. The echoMAP 42dv 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 free HomePort™ planning software. Use the User Data Sharing Cable to share waypoints and routes between multiple devices.

Upgrade with the Best Garmin Maps on the Water

With the optional BlueChart g2 Vision SD card, you can add a whole new dimension of exceptional features to your chartplotter.

  • MarinerEye view and FishEye view provide a 3-D perspective, both above and below the waterline.
  • High-resolution satellite images and aerial photographs help orient you in unfamiliar areas.
  • Auto Guidance technology searches through all relevant charts to create a route you can actually follow — one that avoids obstacles, shallow water, buoys and other obstructions. Just enter your destination and Auto Guidance will take you there on a safe path.

Heading and Position Refreshed 5 Times per Second

Fast, responsive 5 Hz GPS/GLONASS refreshes your position and heading 5 times each second to make your movement on the screen more fluid. It makes dropping up to 5,000 accurate waypoints and finding your way back to your secret fishing hot spots quick and easy.

Take Your echoMAP with You

When you’re off the water, it’s easy to keep your echoMAP safe and secure. You don’t have to mess with plugging and unplugging wires from the unit because the cords plug directly into the mount. This allows you to quickly install and remove your echoMAP from power and the mount.

¹Applies to versions with transducer included only. No transducer versions support 77/200 kHz and Garmin DownVü/SideVü transducers, sold separately. See transducer selection guide for complete list of compatible transducers.
