Garmin GT17M-THF SS Mid Band Chirp Transducer - 20° - 1kW - 8-Pin

The Garmin GT17M-THF SS Mid Band Chirp Transducer is purpose-built for serious anglers and boaters who demand reliable, high-definition sonar performance in freshwater and coastal environments. This 8-pin transducer delivers the clarity and precision needed to locate structure, baitfish, and game fish with confidence.

Built with stainless steel housing, the GT17M-THF withstands saltwater corrosion and prolonged freshwater exposure without degradation. The 20-degree beam angle and 1 kilowatt power output generate sharp target separation and excellent bottom detail, even at greater depths and higher boat speeds. Chirp sonar technology transmits across a frequency range rather than a single frequency, dramatically improving target definition and reducing false echoes.

This transducer integrates seamlessly with Garmin's full echo map and GPSMAP lineup, providing plug-and-play installation for compatible units via the 8-pin connector. Anglers running traditional transom or shoot-through-hull mounting benefit from its compact, hydrodynamic design, making it adaptable to varied water conditions and bottom compositions.
