Garmin Plate Mount f/DownVu & SideVu Transducer Jack. The mount protects the transducer from underwater obstructions and creates no drag on the boat - all while allowing angle adjustment of the transducer so it is parallel with the water surface. And since the transducer is out of the water sonar will not track bottom when the boat is on plane.
