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 includes a GT20 transducer for traditional Garmin CHIRP 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’ contours as you fish. You own these maps; they’re 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. A quick-release mount also allows you to quickly install and remove your device from power and the mount. Transom and trolling motor mounts are included.
 
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. Garmin CHIRP traditional sonar and CHIRP ClearVü scanning sonar are combined into 1 transducer.
