The Garmin GT15M-IH is an in-hull mid-band CHIRP transducer for high-speed boats, mounting inside a solid fibreglass hull so there is no transom hole or risk of cavitation. It runs 85 to 165 kHz at 600 W and reads to 549 m (1,800 ft.).

Description

The Garmin GT15M-IH brings mid-band CHIRP traditional sonar to boats that benefit from an in-hull installation. By bonding inside a solid fibreglass hull, the transducer keeps reading accurately at high speed without the cavitation that can affect transom-mounted units, and it leaves the hull free of through-holes.

The 85 to 165 kHz frequency range delivers clear bottom definition and good target separation, with 600 W of power reaching to 549 m (1,800 ft.). The kit includes four tanks (0, 5, 12 and 20 degrees) so the transducer can be levelled to hull deadrise angles from 0 to 25 degrees, on solid fibreglass up to 16 mm (5/8 in.) thick. It connects to compatible Garmin chartplotters through an 8-pin connector.

Why choose an in-hull transducer like the GT15M-IH?
An in-hull transducer bonds inside a solid fibreglass hull, so it keeps reading accurately at high speed where transom-mounted transducers can suffer from cavitation, and it avoids drilling holes through the hull.
What sonar does the GT15M-IH provide?
It provides mid-band CHIRP traditional sonar at 85 to 165 kHz with 600 W of power, for clear bottom definition and good target separation. It does not include scanning sonar.
What hulls is the GT15M-IH suitable for?
It is for solid fibreglass hulls up to 16 mm (5/8 in.) thick with no dead air space or coring. Four tanks (0, 5, 12 and 20 degrees) allow it to be levelled to hull deadrise angles from 0 to 25 degrees.
How deep can the GT15M-IH read?
It reads to a maximum of 549 m (1,800 ft.), depending on water conditions and the chartplotter or fishfinder model.
What connector does the GT15M-IH use?
It uses an 8-pin Garmin transducer connector with a 6 m (20 ft.) cable. Some chartplotters require a Garmin adapter cable, sold separately.
