It’s time you started fishing with the power of CHIRP sonar. The easy-to-install, easy-to-use 4.3-inch echoMAP CHIRP 42dv is available with or without transducer for high wide CHIRP sonar and Garmin CHIRP DownVü, the clearest scanning sonar on the water. 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.
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.
Clearest Scanning Sonar on the Water
Garmin DownVü scanning sonar gives you a nearly photographic image down to 750 feet below your boat. You clearly see structure, submerged objects and fish. Traditional Garmin HD-ID™ sonar and DownVü 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 echoMAP CHIRP 42dv. It instantly creates your own personalized HD fishing maps on screen with 1-foot contours. Tailor the maps as needed; you own them. Keep the data for yourself, or share it with Garmin or your friends. No special surveying expertise is required. You just fish while Quickdraw Contours creates maps. There’s no waiting around or sending your files away like other mapping software requires — your results appear instantly. Use with any Garmin Panoptix™ transducer, any HD-ID sonar, any CHIRP-enabled, Garmin DownVü transducer or NMEA 2000®-compatible depth transducer. 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.
¹BlueChart g2 Vision or LakeVü HD Ultra SD card is required for this technology.
