Garmin Echomap Plus 42 CV Fishfinder/GPS + Transducer 77/200/455/800 kHz

Echomap plus 42CV

It’s time you started fishing with the power of CHIRP sonar. The easy-to-install, easy-to-use 4.3-inch echoMAP CHIRP 45dv chartplotter is compatible with the GT20-TM transducer which features high wide CHIRP sonar and Garmin CHIRP ClearVü for clear scanning sonar images. It includes Quickdraw Contours software to instantly create your very own HD maps with 1-foot contours as you fish. Internal 5 Hz GPS updates position and heading 5 times per second. Cords plug directly into the mount, allowing you to quickly install and remove your device from power and mount. Transom and trolling motor mounts included with the GT20-TM bundle.

Garmin CHIRP

The built-in sonar capabilities of echoMAP CHIRP 42 CV include CHIRP sonar, the most sophisticated sonar technology available for the fishing and boating public. CHIRP sonar provides amazingly clear target separation and definition because it puts even more energy onto the target than traditional sonar. It 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 HomePort planning software. Use the user data sharing cable to share waypoints and routes between multiple devices.



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

Quickdraw Contours

Instantly create personalised HD fishing maps onscreen with 1-foot contours. 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.


The Best Nautical Charts

A single microSD card slot provides expandable memory for accessory map purchases, such as BlueChart g2 HD or BlueChart g2 Vision HD, which adds Garmin patented Auto Guidance¹ and other great features.

GT20-TM Transducer

Get super crisp detailed views of fish, structures and objects that lie underneath your boat.

Sonde GT20-TM

Easy to Install and Remove

When you’re off the water, it’s easy to keep your echoMAP CHIRP 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 CHIRP from power and the mount.
