MODEL 236

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.
