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. Whether you're targeting deep-water walleye, suspended stripers, or structure-hugging bass, this mid-band solution bridges the gap between narrow-beam sensitivity and broader coverage area that modern fish finders require.

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—a critical advantage when navigating murky water or dense vegetation. The mid-band frequency sweet spot balances range and resolution, making this transducer adaptable to varied water conditions and bottom compositions.

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 that minimizes drag and turbulence. Professional guides and tournament competitors trust Garmin's mid-band architecture for consistent performance across multiple seasons and water types. Weighing 10.9 pounds, the unit is substantial enough to maintain stable signal transmission while remaining practical for most recreational and commercial vessel applications.
