Click here to view the Compatible Transducer Selection Guide The Garmin CHIRP difference The built-in sonar capabilities of ECHOMAP Plus 92sv include our 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.
