Airmar B175C-20-H 20d Tilt With Garmin 12-Pin MM Cable

The Airmar B175C-20-H 20d Tilt With Garmin 12-Pin MM Cable is a professional-grade through-hull transducer engineered for serious anglers and boaters who demand accurate sonar performance in demanding freshwater and saltwater environments. Whether you're targeting deep structure, suspended fish, or running shallow flats, this transducer delivers the precise, real-time bottom imaging and fish detection that separates successful trips from wasted fuel. Designed for seamless integration with Garmin chartplotter systems, it handles the rigorous demands of both tournament fishing and recreational cruising.

Built with Airmar's proven ceramic technology, the B175C-20-H delivers a 20-degree beam angle that balances wide coverage with precise target resolution—ideal for identifying hard bottom, vegetation, and baitfish presentations across varying depths. The tilt mechanism allows convenient adjustment for optimal transducer positioning, reducing turbulence interference and ensuring clean signal transmission in all hull configurations. The pre-wired Garmin 12-pin MM connector eliminates installation guesswork and ensures plug-and-play compatibility with compatible Garmin systems, while the through-hull mount provides maximum stability and minimal signal loss over extended operating hours.

This transducer is ideal for fiberglass and composite hull boats where through-hull installation delivers superior performance compared to in-hull alternatives. Installation requires drilling a hole and securing the transducer with the included hardware—a straightforward procedure for most boat owners or marine technicians. The 12-pin Garmin connector ensures compatibility with a wide range of Garmin fishfinders and integrated navigation systems, making this an excellent upgrade or replacement for existing sonar installations seeking improved definition and reliability on the water.
