Sonar Modules

Most Garmin chartplotters — even if they did not come as combos with built-in sonar — can add Garmin CHIRP sonar, Garmin CHIRP DownVü™ and CHIRP SideVü™ scanning sonar, with the clearest scanning sonar images on the water. We made our sonar modules incredibly easy to install, easy to understand and seriously easy to use. That’s the power of simple.
