Garmin Fish Finder Accessories Marine

Easily attach your compatible 4-, 8- or 12-pin scanning transducer to the
jack plate of your boat with this mount, which provides excellent sonar
returns at low speeds. 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.
