The Garmin CHIRP Difference

The built-in sonar capabilities of echoMAP 42dv 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.

Clear Scanning Sonar Images

Garmin ClearVü scanning sonar gives you a nearly photographic 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 1 transducer. Also provides HD-ID support for Minn Kota® and MotorGuide® trolling motors with integrated transducers.

Create your own HD maps

Quickdraw Contours is a free, easy-to-use software feature already installed on your compatible Garmin combo. It instantly creates your own personalized HD fishing maps with 1-foot contours. Tailor them to fit your needs. They are your maps — you own them. Keep the data to yourself, or share it with the Quickdraw Community on Garmin Connect™. There’s no special surveying expertise required. You just fish while it creates maps. You don’t have to wait around or send your files away like other mapping software requires — your results appear instantly. Use with any of the following sonar transducers:  Garmin Panoptix™, HD-ID™ traditional, CHIRP-enabled, Garmin ClearVü™ or NMEA 2000^®-compatible depth. Have more than 1 sonar device installed onboard? Quickdraw Contours automatically selects the most capable sonar device to provide the very best results for you!

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. 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 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.

Upgrade with the Best Maps on the Water

A single microSD™ card slot provides expandable memory for accessory map purchases such as BlueChart® g2, BlueChart® g2 Vision®, LakeVü HD or LakeVü HD Ultra. LakeVü HD Ultra and BlueChart g2 Vision provide exclusive Garmin Auto Guidance, a technology that directs you to your hot spots by instantly creating an on-screen path based on your boat’s specifications that you can follow to avoid shallow water and other charted obstructions.

Enhanced Auto Guidance

Just enter the location where you want to go and patented Garmin Auto Guidance technology instantly searches through relevant charts to create a safe, virtual pathway on the display that helps you avoid low bridges, shallow water and other charted obstructions en route.

With enhanced Version 2.0, you have access to more features and capabilities. You’re able to adjust the calculated Auto Guidance pathway by inserting “via” points at interim stops or landmarks along your desired route. You can easily review hazard points along your calculated path. And you can even engage your compatible Garmin autopilot to follow the Auto Guidance route, automatically. Other 2.0 enhancements give you the ability to calculate arrival times at any point on your route (great for timing arrivals to correspond with bridge openings and other time-critical events). Better still, you can now save your plotted Auto Guidance paths for future navigation by backing them up on an SD™ card with your BlueChart g2 Vision or LakeVü HD Ultra cartography¹.

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 - now it’s easier than ever to transfer those items to your new Garmin chartplotter, via industry-standard GPX software formatting. GPX is an open standard format for GPS data exchange across platforms and applications. With this easy-to-use interface technology, Garmin has taken “no waypoint left behind” to a whole new level of trade-up convenience.

Multiple Depth Range Shading

Designate up to 10 different depth ranges each with its own color. Makes it easier to view target depths at a glance.
