Easily attach your compatible 4, 8 or 12 pin converter to your boats rear mirror with this mount that provides excellent sonar return at all speeds. Since the transducer is in the water at all times, the bracket does not protect the transducer from underwater obstructions and there will be some resistance on the boat. The included transducer splash guard reduces excessive water splashes from your compatible converter when your boat runs at high speeds. You can also mount the transducer to the step of your boat with this bracket to allow the angle adjustment of the transducer so that it is parallel to the water surface; this does not create resistance on the boat. And since the transducer is out of the water with this mounting style, sonar will not track the ground when the boat is on the plane.
