Garmin GT15M-THF 0 Degree 600W SS Thru-Hull Transducer

Engineered for reduced drag and optimum sonar performance on midsize fishing and cruising boats, the Garmin GT15M-THF 0 Degree 600W SS Thru-Hull Transducer is a flush-mounted powerhouse that delivers high-definition mid-band CHIRP sonar. It clearly defines fish arches, structure, and bottom depth on your display, helping you fish smarter and navigate confidently.

Key advantages

• Mid-band CHIRP sonar delivers high-definition targets and structures with clear separation, down to 1,200 ft in saltwater and 1,900 ft in freshwater.
• 600 W power in a rugged stainless steel thru-hull housing for reliable performance in demanding conditions.
• Frequency range 85–165 kHz provides a broad, yet precise coverage area, producing crisp fish arches and accurate depth readings.
• Through-hull flush mounting minimizes drag while optimizing beam orientation for cleaner sonar returns.
• Auto-ID technology enables plug-and-play operation by automatically configuring the sonar to the transducer.
