Airmar SS175C-20-MThru Hull 20 Deg Tilt Medium CHIRP with Raymarine 11-Pin

The Airmar SS175C-20-M Thru Hull 20 Deg Tilt Medium CHIRP with Raymarine 11-Pin connector is a precision marine transducer built for serious anglers and boaters who demand reliable sonar performance in demanding water conditions. This through-hull mount transducer integrates seamlessly with Raymarine chartplotters and fishfinders, delivering the real-time target definition and bottom discrimination that separates productive fishing days from frustrating blank water searches. Whether you're working deep offshore structure, shallow weedy bays, or transitional zones where fish congregate, this transducer provides the acoustic clarity needed to locate and identify fish with confidence.

The SS175C-20-M employs medium-frequency CHIRP technology, which sweeps a continuous range of frequencies to produce superior target separation and detailed bottom structure imaging compared to traditional single-frequency transducers. The 20-degree tilt angle reduces turbulence and cavitation at speed, ensuring clean sonar returns even when running at cruising velocity—a critical advantage for boats that spend time underway. The through-hull installation offers better coupling to the hull than transom-mount alternatives, reducing signal loss and delivering stronger echoes from suspended baitfish and gamefish. At 11 pounds, the transducer is engineered for balanced weight distribution, and its Raymarine 11-pin connector ensures plug-and-play compatibility with the full Raymarine AXIOM, ELEMENT, and legacy series systems.

This transducer excels for boaters running fiberglass hull vessels in saltwater, freshwater, and brackish environments where through-hull mounting is feasible and preferred. Retrofit installation requires cutting a mounting hole and routing the cable through the hull—a task best handled by qualified marine technicians to ensure proper sealing and performance. The Raymarine 11-pin connector works with mid-range and professional-grade systems, making this an ideal upgrade for anglers transitioning from basic sonar to advanced structure-scanning technology. Professional installation ensures years of reliable service and protects your electronics investment.
