ECHOMAP™ Plus 42cv - mit Geber GT20-TM

This compact combo has lots of built-in benefits. Easy-to-install and even easier to use, it has a bright 4.3” display that is easy to read on a sunny day on the water. It features built-in support for Garmin CHIRP traditional sonar that delivers remarkable target separation and CHIRP ClearVü scanning sonar for nearly photographic images of what’s below the boat. It comes with a preloaded worldwide basemap and is compatible with our BlueChart g3 and premium BlueChart g3 Vision coastal charts with integrated Navionics data and Auto Guidance¹ technology. Plus, it has Quickdraw Contours mapping software to instantly create personalised fishing maps on-screen with 1 foot contours as you fish. You own these maps. They are yours to keep private or share with the Quickdraw Community on Garmin Connect^™. Plus, you can share waypoints and routes with other ECHOMAP or STRIKER units. It also features a quick-release mount allowing you to quickly remove your device from power and mount. 

The Garmin CHIRP difference

The built-in sonar capabilities of ECHOMAP Plus 42cv include our CHIRP traditional sonar, one of the most sophisticated sonar technologies available for the fishing and boating public. CHIRP traditional sonar provides amazingly clear target separation and definition, because it puts even more energy onto the target than traditional sonar. It also provides traditional sonar support for Minn Kota^® and MotorGuide^® trolling motors with integrated transducers.

Clear scanning sonar images

Garmin CHIRP ClearVü scanning sonar gives you a nearly photographic image of what’s below your boat. You clearly see structure, submerged objects and fish.

Quickdraw contours to create your own maps

Instantly create personalised fishing maps on-screen with 1 foot contours as you fish. Tailor them to fit your needs. These are your maps — you own them. Keep the data to yourself, or share it with the Quickdraw Community on Garmin Connect.

Upgrade to our best maps on the water

Step up to Garmin LakeVü g3, Garmin LakeVü g3 Ultra, Garmin BlueChart g3 or Garmin BlueChart g3 Vision2, all with integrated Navionics data, Auto Guidance technology and other great features. A single microSD™ card slot provides expandable memory for accessory map purchases.

Take Your ECHOMAP Plus with You

When you’re off the water, it’s easy to keep your Garmin ECHOMAP Plus combo 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 Garmin ECHOMAP Plus from power and the mount.
