GT12M Bronze Thru-Hull Transducer - 350W

Engineered for superior drag reduction and exceptional sonar performance on midsized fishing and cruising vessels, this flush-mounted 350-watt mid-band CHIRP transducer distinctly identifies fish, structures, and bottom depth on your display.

Mid-Band Chirp Traditional Sonar

This 8-pin, 350-watt bronze thru-hull transducer delivers high-resolution mid-band CHIRP sonar, defining fish targets and structures down to 800 feet in saltwater and 1,200 feet in freshwater.

Wide Frequency Range

Customize your frequency based on your fishing environment. This transducer operates in the medium frequency range, cycling between 85–165 kHz for comprehensive coverage, crisp fish arches, and precise depth information.

Enhanced Ping Sensitivity

Featuring superior sonar sensitivity and low noise, this robust transducer provides high resolution and excellent target separation, allowing for easy identification of fish and structures on compatible chartplotters.

Effortless Thru-Hull Installation

Its resilient bronze housing and stem ensure simple thru-hull flush mounting, minimizing drag while optimizing beam orientation for clear sonar results.

Auto-ID Technology

Experience hassle-free installation with Garmin's auto-identification technology, which enables the sonar to self-configure based on the transducer being utilized.

Versatile Hull Compatibility

Designed to accommodate a range of boat hull materials, including fiberglass, composite, and wood, this transducer is available in various tilt configurations to suit deadrise angles from 0 to 20 degrees without needing a fairing block.
