Airmar SS175C-20-H 20d Tilt High CHIRP With No Connector

The Airmar SS175C-20-H 20° Tilt High CHIRP transducer is a professional-grade sounder for serious anglers and boaters who demand accuracy in both shallow and deep water. Built for dual-frequency operation, this bronze thru-hull transducer combines fast-response water temperature sensing with industry-leading CHIRP broadband imaging. Weighing 11 pounds and engineered for side-by-side mounting or retrofit applications, it delivers the reliable target separation and bottom detail that separate consistent fishermen from casual operators on the water.

Operating at peak power of 1 kilowatt, the SS175C produces high-frequency CHIRP signals spanning 130 kHz to 210 kHz with a tight 10° to 6° beamwidth across its frequency range. This narrow cone geometry cuts through clutter and noise while maximizing bottom penetration to a maximum depth of 1,000 feet (304 meters)—more than sufficient for offshore structure, canyon drop-offs, and mid-depth pelagic work. The integrated temperature sensor responds quickly to thermocline transitions, critical data for baitfish and gamefish location. The 20° tilt housing accommodates mounting angles that optimize transducer beam geometry on hulls with varying deadrise, and the no-connector design simplifies integration with compatible Garmin, Lowrance, and Simrad chartplotter systems that accept direct Airmar installations.

Inshore guides, tournament anglers, and vessel operators running 25-foot offshore and center console rigs benefit most from this transducer's combination of depth capability and high-resolution imaging. Installation requires thru-hull mounting, proper transducer well preparation, and compatible sounder hardware; consult your chartplotter manual for cable routing and connector compatibility. Its proven Bronze construction and Airmar reputation make this an industry standard for reliability in saltwater and freshwater applications where temperature data and detailed structure-finding are non-negotiable.
