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

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

Designed for reduced drag and optimum sonar performance on fishing and cruising boats, this flush-mounted 1 kW mid-band CHIRP (80–165 kHz) transducer clearly defines fish arches, structure, and bottom depth returns on the display.

This 8-pin 1 kW stainless steel thru-hull transducer features high-definition mid-band CHIRP sonar that clearly defines fish targets and structures down to 1,800’ in saltwater and 2,400’ in freshwater.

• Transom-mount transducers are typically the simplest retrofit option, but placement still matters for clean water flow and reliable readings at speed.
• This listing is built around the 8-pin connector style shown in the product data. Confirm adapter needs if your Garmin unit uses a different sonar port.

Will this work with every Garmin unit?
No. Compatibility depends on your Garmin display, sonar port, connector, and supported sonar type.

How do I choose the right tilt or deadrise?
For tilted-element thru-hull models, match the transducer angle to your hull deadrise so the sonar beam points correctly in the water.

Should I confirm before ordering?
Yes. Transducers are highly installation-specific, especially thru-hull, in-hull, pocket-mount, and high-power CHIRP models.
