Garmin GT17M-THF SS Mid Band Chirp Transducer - 0° - 1kW - 8-Pin

The Garmin GT17M-THF SS Mid Band Chirp Transducer is the go-to sounder solution for serious anglers and boat owners who demand reliable, crystal-clear underwater imaging in freshwater and inshore environments. Whether you're targeting structure in lakes, rivers, or coastal shallows, this mid-band transducer delivers the frequency range and power output that produces detailed bottom readings and fish arches at working depths most anglers encounter. Built with a stainless steel housing for corrosion resistance, this 8-pin transducer integrates seamlessly with compatible Garmin chartplotters and fish finders, giving you the confidence to locate productive zones quickly and fish with precision.

This transducer operates at 1 kilowatt of transmit power—robust enough to cut through murky water and deliver strong return signals even in weeds or heavy cover. The mid-band CHIRP (Compressed High-Intensity Radar Pulse) sonar technology sweeps across a frequency range rather than pulsing a single frequency, dramatically improving target separation and reducing noise interference. The 0° cone angle creates a narrow, focused beam that excels at identifying tight bottom structure, thermoclines, and suspended fish with minimal dead zones. Weighing 11 pounds and designed for standard transom or through-hull mounting, it balances ease of installation with the durability needed for seasons of heavy use on the water.

Anglers upgrading older sonar systems or installing a dedicated high-performance unit will appreciate the proven reliability and real-time responsiveness this transducer brings to any Garmin-compatible system. Boaters running lakes, rivers, and nearshore fisheries benefit most from mid-band performance—it strikes the ideal balance between water penetration and target detail that recreational and serious tournament anglers depend on. The 8-pin connector ensures straightforward integration with current and legacy Garmin units; verify your chartplotter's compatibility before purchase to confirm connector type and sonar module support for seamless operation.
