Housings for Through-Hull Transducers

Housings are available in plastic, bronze or stainless steel. Low profile housings protrude slightly from the hull. Flush housings are set in flush to the hull but need careful preparation of the mounting area.

Some housings have integral valve assemblies to slow water ingress when an insert is removed to clean the transducer face or paddlewheel.
