A wedge shaped transom mount transducer that can be located below the hull
line. This is particularly desirable to avoid the flow of turbulent water
created by rivet heads on aluminum boats. Also recommended if deadrise is
to great for flush mounted transducer (Model 231). Made of ABS high impact
plastic.
Options:
Temperature sensor.
