The Garmin CHIRP difference

The built-in sonar capabilities of Garmin ECHOMAP Plus 45cv include Garmin’s CHIRP traditional sonar, one of the most sophisticated sonar technologies available for the fishing and boating public. CHIRP traditional sonar provides amazingly clear target separation and definition, because it puts even more energy onto the target than traditional sonar. It also provides traditional sonar support for Minn Kota and MotorGuide trolling motors with integrated transducers.

Clear scanning sonar images

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

Preloaded BlueChart g2 charts

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.

Quickdraw Contours to create your own maps

Take your ECHOMAP Plus with you

When you’re off the water, it’s easy to keep your ECHOMAP Plus combo 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 Plus from power and the mount.
