It’s time you started fishing with the power of CHIRP sonar.

The Garmin echoMAP™ series of chartplotter/sonar pushbutton combos have built-in Garmin HD-ID™ traditional sonar plus ClearVü that provides the clearest scanning sonar images on the water. They have the most accurate GPS for its class. This version is preloaded withBlueChart g2 HD coastal and offshore maps and includes a GT20-TM transducer.

ClearVü scanning sonar is built into echoMAP™ cv combos. ClearVü gives you the clearest, nearly photographic sonar view of what’s below your boat. It uses an all-in-one HD-ID™ and ClearVü transducer allowing you to have both traditional and ClearVü images on your screen.

The Garmin CHIRP difference: The built-in sonar capabilities of echoMAP 44cv 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.

Clearest scanning sonar images: 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. Traditional Garmin HD-ID™ sonar and ClearVü scanning sonar are combined into one transducer. Also provides HD-ID support for Minn Kota® and MotorGuide® trolling motors with integrated transducers.

Preloaded BlueChart g2 HD Maps: echoMAP CHIRP 44cv is preloaded with BlueChart g2 HD maps covering the coastal U.S. (East Coast, West Coast, Gulf of Mexico, U.S. and Canadian sides of the Great Lakes). It also includes all U.S. charts for the entire coastline as well as everything available on NOAA charts. In addition to the basic charts, tidal stations, currents, depth contours, IALA symbols and included fishing charts, BlueChart g2 HD offers smooth transitioning between zoom levels and more seamless continuity across chart boundaries. Customize your screens with Shallow Water Shading, which allows you to contour shade for all depth contours shallower than what you determine is your safe depth. Fishing charts emphasize bathymetric contours with less visual clutter on the display. And there's also a choice of standard 2-D direct overhead or 3-D "over-the-bow" map views for easier chart reading and orientation. Garmin New Chart Guarantee

Quickdraw Contours to create your own HD maps: Instantly create personalized 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™.

Heading and position refreshed five times per second: Fast, responsive 5 Hz GPS and GLONASS refreshes your position and heading 5 times each second to make your movement on the screen more fluid. Now it's quick and easy to drop up to 5,000 accurate waypoints and find your way back to your secret fishing hot spots.

Take your echoMAP CHIRP with you: 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.

Upgrade to the best maps on the water: A single microSD™ card slot provides expandable memory for accessory map purchases, such as LakeVü HD Ultra with Max Def Lakes or BlueChart® g2 Vision® HD, which adds Garmin patented Auto Guidance¹ and other great features.

GPX Waypoints transfer: If you have waypoints, tracks or frequently used routes stored on another manufacturer's GPS product—or on a Garmin handheld device—it’s easy to transfer those items to your new Garmin chartplotter via industry-standard GPX software formatting.
