Description

The Garmin GT15M-TM is a transom-mount transducer built around mid-band CHIRP traditional sonar. The 85 to 165 kHz frequency range provides excellent target separation and clear bottom definition, making it a strong choice for anglers who want crisp fish arches across a wide range of depths.

With 600 W of transmit power, the GT15M-TM reads to 579 m (1,900 ft.) in freshwater, suiting both inshore and deeper freshwater fishing. It mounts on the transom at angles from 0 to 70 degrees, includes a fast-response temperature sensor, and connects to compatible Garmin chartplotters through an 8-pin connector with a generous 9 m (30 ft.) cable.

What type of sonar does the GT15M-TM provide?
It provides mid-band CHIRP traditional sonar across 85 to 165 kHz, which gives clear bottom definition and crisp fish arches with excellent target separation. It does not include ClearVu or SideVu scanning sonar.
How deep can the GT15M-TM read?
It reads to a maximum of 579 m (1,900 ft.) in freshwater, depending on water conditions and the chartplotter or fishfinder model.
How is the GT15M-TM mounted?
It is a transom-mount transducer supporting transom angles from 0 to 70 degrees. Mounting hardware and a built-in temperature sensor are included.
What connector and cable length does the GT15M-TM use?
It uses an 8-pin Garmin transducer connector with a 9 m (30 ft.) cable. Some chartplotters require a Garmin adapter cable, sold separately.
What is the difference between the GT15M-TM and GT15M-IH?
Both share the same mid-band CHIRP sonar at 85 to 165 kHz and 600 W. The TM version mounts on the transom, while the IH version is designed to be installed inside the hull for high-speed boats where transom cavitation could be an issue.
