Bronze Thru hull Transducer Bronze Thru-Hull Transducers are for large boats and for boats with in-board motors that make typical Transom Mount Transducers ineffective. They are not recommended for trailered boats as the transducer is not flush with the hull. Bronze Thru-Hull Transducers require that a hole be drilled in the hull and the shaping of a fairing block. Professional installation is recommended. Plastic Thru-Hull Transducers are an alternative to Bronze Thru-Hull Transducers Description: Bronze thru hull transducer, dual beam, 1 kilowatt, 200/50kHz.
