Airmar B175C-12-H Thru Hull With 9-Pin Navico MM Cable

The Airmar B175C-12-H Thru Hull With 9-Pin Navico MM Cable is the workhorse transducer for serious anglers and boaters who demand reliable sonar performance in freshwater and moderate saltwater environments. This thru-hull mount transducer delivers the consistent bottom-reading capability and fish-finding accuracy that veteran anglers depend on when deploying their electronics systems. Whether you're running a dedicated fishfinder or integrated GPS/sounder combo, this transducer integrates seamlessly into Navico-equipped systems and provides the real-time acoustic data needed to locate structure, depth changes, and gamefish with confidence.

The thru-hull design eliminates speed loss and performance degradation that can occur with transom-mounted alternatives, offering superior cone angle coverage and minimal water-flow interference at cruising speeds. The 9-pin Navico MM cable connector ensures plug-and-play compatibility with compatible Navico chartplotter and sounder units, reducing installation complexity and wiring errors. At 12 pounds, this transducer carries sufficient weight and build quality to withstand years of saltwater spray, thermal cycling, and the constant vibration of extended on-water use—characteristics that separate commercial-grade marine electronics from consumer-grade alternatives.

This transducer is ideal for center-console boats, bay boats, and larger recreational vessels where thru-hull installation space exists and maximum sonar performance justifies the installation investment. Professional guides, tournament anglers, and recreational boaters operating 20- to 45-foot vessels benefit most from the stable mounting platform and signal clarity this transducer provides. Confirm your vessel's existing sounder or chartplotter connectivity before purchase to ensure the 9-pin Navico MM cable matches your installed Navico hardware; proper integration ensures years of reliable fish detection and navigational confidence on the water.
