Garmin GT8HW-IH

Garmin's GT8HW-IH 8-pin in-hull transducer makes it easier to find fishing spots thanks to high-wide CHIRP sonar that'll let you maintain depth accuracy, even when your craft is moving quickly. Got a fiberglass bass boat? Installing this transducer in the hull will help you avoid transom-mounted issues caused by cavitation bubbles. It boasts 250 watts of power so it can read down to 800 feet in freshwater. Pair it with select Garmin transom-mount transducers and an adapter cable so you can maintain depth at high speeds and scanning capabilities at trolling speeds. The GT8HW-IH's included cable runs 20 feet, and Garmin gives you an in-hull fitting to help with installation.
