Humminbird XBTH-9-QB-90-T Bronze Thru-Hull Transducer

Features: 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. 30' cable and hardware included - fairing block not included.
