Easily attach your compatible 4-, 8-, or 12-pin transducer to the transom of your boat with this mount, providing excellent sonar returns at all speeds. While the transducer remains in the water at all times, this mount doesn’t protect it from underwater obstructions and can cause some drag on the boat. The included transducer spray shield reduces excessive water spray at high speeds. Alternatively, you can mount the transducer to your boat’s step for angle adjustment, keeping it parallel to the water surface to eliminate drag. However, when the transducer is out of the water with this mounting style, sonar will not track the bottom when the boat is on plane.
