Airmar B175C-20-HW 20d Tilt With 9-Pin Navico MM Cable

The Airmar B175C-20-HW 20d Tilt With 9-Pin Navico MM Cable is a professional-grade through-hull transducer purpose-built for anglers and boaters who demand reliable, consistent sonar performance in freshwater and light saltwater environments. After years on the water, any experienced angler knows that accurate fish-finding starts with a quality transducer—one that delivers crisp bottom readings, clear target separation, and stable performance across varying depths and water conditions. This Airmar unit has earned its reputation among serious fishermen and boat owners who refuse to compromise on fish detection accuracy.

The B175C operates at 20 kHz frequency, a sweet spot for anglers targeting mid-range depths where most freshwater and inshore game fish hold. The tilting mount design allows you to adjust the transducer face to optimize beam angle and reduce turbulence-induced noise during high-speed runs—a critical feature when your GPS speed climbs above 30 knots. The 9-pin Navico MM connector ensures seamless integration with compatible Navico chartplotters and multifunction displays, eliminating compatibility headaches and simplifying installation. Built to withstand corrosion and mechanical stress, this transducer delivers the durability boaters expect from Airmar's proven engineering, even after hundreds of hours in harsh marine conditions.

This transducer is ideal for center-console fishing boats, bass boats, and cruisers equipped with Navico sonar systems—particularly those running Simrad, B&G, or Lowrance units that support the 9-pin MM connector standard. If you're upgrading an aging transducer or retrofitting a boat with fresh sonar capability, verify your chartplotter's connector type and frequency requirements before purchase. The tilting bracket accommodates hull mounting angles from nearly vertical to moderately raked transoms, making installation straightforward on most modern hulls. Weighing 12 lbs, it's substantial enough to stay put in rough conditions while remaining light enough for hassle-free mounting.
