Airmar SS175C-20-HW 20d Tilt High Wide CHIRP wIth Navico 9-Pin

The Airmar SS175C-20-HW 20° tilt high wide CHIRP transducer with Navico 9-pin connector is a professional-grade sounder for serious anglers and boaters who demand reliable depth readings and precise water temperature data in diverse fishing conditions. Built for saltwater and freshwater applications, this through-hull transducer delivers the clarity and speed required to locate structure, thermoclines, and baitfish concentrations across a wide coverage area. Whether you're running coastal ledges, inland reservoirs, or anything in between, this transducer integrates seamlessly with compatible Navico chartplotter systems for real-time sonar intelligence.

Rated at 1 kilowatt power output, the SS175C-20-HW reaches maximum depths of 500 feet, providing the penetration needed for offshore and deep-lake work while maintaining excellent near-bottom resolution. The dual-frequency CHIRP sonar engine operates across high frequencies of 150 kHz to 250 kHz, producing a sharp, consistent 25° beam pattern that covers structure without excessive noise or target confusion. The integrated fast-response water temperature sensor enables real-time thermal profiling—critical for identifying temperature breaks where game fish congregate. The 20° tilt housing allows flexible transducer mounting angles to suit various hull designs and reduce turbulence interference, while the Navico 9-pin connector ensures plug-and-play compatibility with established marine electronics networks.

This transducer is ideal for anglers upgrading existing Navico systems or building a cohesive sonar platform without proprietary hardware conflicts. The high-wide CHIRP architecture excels in scenarios where you need both coverage and detail—shallow flats work, deep structure hunting, and mid-water baitfish detection all benefit from the balanced beam geometry. Installation requires basic through-hull mounting knowledge and should be positioned to avoid prop wash and engine noise; many boaters find professional installation worthwhile to ensure optimal transducer orientation. At 11 pounds, it integrates into most hull configurations without significant weight distribution concerns, making it a reliable long-term upgrade for vessels already committed to Navico electronics ecosystems.
