GT12M Bronze Thru-Hull - 350W - 0 Degree

Designed for reduced drag and optimum sonar performance on midsize fishing and cruising boats, this flush-mounted, 350-watt mid-band CHIRP transducer clearly defines fish arches, structure, and bottom depth returns on your display.

Midband Chirp Traditional Sonar

This 8-pin, 350-watt bronze thru-hull transducer features high-definition mid-band CHIRP sonar that clearly defines fish targets and structures down to 800’ in saltwater and 1,200’ in freshwater.

Broad Frequency Range

Use the perfect frequency for the waters you’re fishing. Covering the medium frequency range, this transducer pulses from 85–165 kHz, displaying a wide coverage area, crisp fish arches, and accurate depth readings.

Optimum Ping Sensitivity

Offering excellent sonar sensitivity, low noise, high resolution, and good separation of targets, this robust transducer makes it easier than ever to distinguish fish and structure on your compatible chartplotter display.

Thru-Hull Installation

A durable bronze housing and stem offer straightforward thru-hull flush mounting for minimum drag and optimum beam orientation for clear sonar returns.

Auto-ID Technology

Enjoy simple plug-and-play operation with Garmin auto-identification technology — which enables the sonar to automatically configure itself to the transducer being used.

Fits Various Hull Types

Configurable for a wide variety of boat hull materials, including fiberglass, composite, and wood, the transducer is available in a range of tilt versions to accommodate deadrise angles of 0–20° without a fairing block.
