The Garmin water speed sensor easily calculates the speed of the water flowing past your boat transducer, collects it, and sends it to your fish finder or other sounder device. Simply mount the 6-pin speed sensor on the transom of your boat and connect it to your fishfinder / depth finder. The paddle wheel on the Garmin speed sensor turns as the vessel moves through the water, collecting speed data to display on your sonar device.
The speed sensor transducer kit comes with mounting hardware and installation instructions and an integrated y-cable so you can add water speed to a Garmin 6-pin sounder.
