Garmin GT15M-THF 20 Degree 600W Stainless Steel Thru-Hull Transducer for Midsize Boats

GT15M-THF 20 Degree 600W SS Thru-Hull Transducer

Designed for reduced drag and optimum sonar performance on midsize fishing and cruising boats, this flush-mounted, 600-watt mid-band CHIRP transducer clearly defines fish arches, structure, and bottom depth returns on the display.

Midband Chirp Traditional Sonar

This 8-pin, 600-watt stainless steel thru-hull transducer features high-definition mid-band CHIRP sonar that clearly defines fish targets and structures down to 1,200 in saltwater and 1,900 in freshwater.

Broad Frequency Range

Use the perfect frequency for the waters being fished. Covering the medium frequency range, this transducer pulses from 85165 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 a compatible chartplotter display.

Thru-Hull Installation

A durable stainless steel 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 configure itself to the transducer being used automatically.
