Garmin GT15M-THF Stainless Steel Thru-hull 12° Tilted Element CHIRP Transducer delivers high-definition sonar performance for midsize fishing and cruising boats. Its flush-mounted, stainless steel housing is built to endure demanding saltwater conditions while reducing drag for smoother hull performance.
Engineered for clarity, the 600-watt midband CHIRP (85–165 kHz) delivers precise structure definition and tight target separation. Expect crisp fish arches that help you distinguish between small baitfish and larger game, even in challenging underwater terrain.
