GT8HW-IH transducer is ideal for bass boats that want to install the transducer inside a fiberglass hull and not on the transom where cavitation could cause issues. It requires a flat section (less than 6°) in the hull to be mounted and is excellent for boats traveling at high speeds that want to maintain accurate depth readings. The 8-pin transducer features high-wide CHIRP traditional sonar (145-230 kHz) and has a power rating of 250 W.
