The Garmin GT17M-THF SS is a stainless steel thru-hull flush-mount transducer designed for fishing and cruising boats that need precise sonar performance without added hull drag. Mid-band CHIRP operation across 80–165 kHz at 1 kW resolves fish arches, bottom structure, and contour detail to 1,800 ft in saltwater and 2,400 ft in freshwater. The 20° tilt accommodates hull deadrise angles from 16° to 24° with no fairing block required, and Garmin Auto-ID lets your compatible sonar unit configure itself automatically at startup. Works with fiberglass, composite, steel, aluminum, and wood hulls.
