For use with our Pole Mount kits.  This is not a required part, but allows for a smoother rotation of the transducer pole; as it allows you to keep the split clamp - that ultimately holds the pole - loose while this shaft clamp sits on top of the split clamp allowing free rotation without loosing your desired depth setting.
