Product Overview

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 (<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. It can be used in conjunction with a GT30-TM transducer and an adapter cable so you can maintain depth at high speeds and scanning capabilities at trolling speeds.
