It’s time you started fishing with the power of CHIRP sonar. The easy-to-install, easy-to-use 4.3″ echoMAP CHIRP 45cv is compatible with optional transducers for high wide CHIRP sonar and Garmin CHIRP ClearVü, the clearest scanning sonar on the water. It Includes Quickdraw Contours software to instantly create your very own HD maps with 30 centimetre contours as you fish. Internal 5 Hz GPS updates position and heading 5 times per second. Cables 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 45cv 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 ClearVü scanning sonar give you a nearly photographic image down to 225 metres 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.

Preloaded UK, Ireland and North West mainland Europe coast maps – Preloaded with Garmin’s highly detailed BlueChart G2 mapping covering the British Isles in their entirety, including the Thames Estuary, Caledonian Canal, Outer Hebrides, Shetland and Orkney Islands, Isle of Wight, Isle of Man, Lough Neagh, The Shannon river (up to Lough Kee) and the Irish Sea. Continental coverage from Brest, FR to Kiel, DE including the Channel Islands, the Waddenzee, the IJsselmeer, the canals of The Netherlands, the Meuse River to Liege, BE; the Rhine River to Dusseldorf, DE and the Kiel Canal.
Create Your Own HD Maps – Quickdraw Contours is a free, easy-to-use software feature already installed on your echoMAP CHIRP 45cv. It instantly creates your own personalised HD fishing maps on screen with 30 centimetre 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 ClearVü 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 cables plug directly into the mount. This allows you to quickly install and remove your echoMAP from power and the mount.
Upgrade with the Best Garmin Maps on the Water – A single microSD™ card slot provides expandable memory for accessory map purchases such as BlueChart® g2 or BlueChart® g2 Vision®. Based on your boat’s specifications, Auto Guidance instantly creates a visual path 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 Vision².
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.¹Maximum depth may be affected by seabed material and salinity and temperature of water.
²BlueChart g2 Vision SD card is required for this technology.
