The difference with Garmin CHIRP

The built-in echo sounder functions in the ECHOMAP Plus 42cv contain traditional CHIRP echo sounder, one of the most sophisticated echo sounder techniques available to the fishing and boat-intensive public. Traditional CHIRP echo sounder provides incredibly clear object separation and definition because it adds even more energy to the target than a traditional echo sounder. It also has traditional echo support for my Kota ® and MotorGuide ® troll motors with integrated sensors.
