Garmin's GT15M-IH transducer is designed for users who want to install the transducer inside a fibreglass hull and not on the transom cavitation could cause issues. The in hull transducer can be used with a hull deadrise angle from 0-25 degrees and is perfect for boats travelling at high speeds that want to maintain pinpoint depth readings.

The 8 pin Garmin transducer has 4 plastic tanks, with a mid-band CHIRP traditional sonar (85-165 KHz) and can be used in conjunction with Garmin's GT30-TM transducer and adapter cable, so you can maintain depth at high speeds and scanning capabilities at trolling speeds.
