The Rooster Rooter is designed to bridge the gap between your Lowrance transducer and the rear of the hull on your boat. This stops water from having the ability to be pushed up between the transducer and hull creating that rooster tail that covers your motor in water spray plus creates turbulence around the transducer which affects the reading on your screen. The Rooster Rooter can be installed in minutes using the new stainless steel fasteners provided and placing it in between the transducer and the mounting bracket. It works with the Lowrance TotalScan, 3-in-1, and 3d structure transducers with both the plastic and stainless steel brackets.
