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, six beam, 53 degree, 455 kHz, 3D sonar applications only. Transducer dimensions: 4.25" diameter X 1.25" D(below hull); Shaft diameter .81". Does not include fairing block.

For Use With: Matrix 47 3D, 947C 3D, Wide 3D Vision, Wide 3D Vista, Wide 3D Paramount
