Garmin GT15M-IH 600W Mid-Band CHIRP In-Hull Transducer – 8 Pin

The Garmin GT15M-IH is a powerful 600W Mid-Band CHIRP in-hull transducer designed for installation inside solid fibreglass boat hulls. It is an excellent option for anglers and boat owners who want strong traditional CHIRP sonar performance without installing a transducer through the hull or externally on the transom. Operating across a CHIRP frequency range of 85–165 kHz, the GT15M-IH provides excellent depth capability, good target separation and clear fish arches, making it particularly well suited to coastal and offshore fishing. Garmin rates the transducer for depths of up to 549 m / 1,800 ft, although actual performance depends on water conditions and the connected sonar unit. Important: Traditional CHIRP Only The GT15M-IH is primarily a traditional Mid-Band CHIRP transducer. It does not provide Garmin ClearVü or SideVü scanning sonar by itself.
