Airmar B175C-12-H Thru Hull With 12-Pin Garmin MM Cable

The Airmar B175C-12-H Thru Hull With 12-Pin Garmin MM Cable is a professional-grade transducer engineered for serious anglers and boaters who demand accurate sonar imaging. Built for permanent hull mounting, this transducer integrates seamlessly with Garmin chartplotters and fish finders that accept 12-pin connectors, making it an ideal upgrade or replacement for vessels already running Garmin marine electronics. Whether you're mapping structure, locating suspended fish, or navigating shallow waters, this thru-hull design delivers the dependable performance required for both freshwater and saltwater applications.

Airmar has engineered this B175C transducer with broadband ceramic technology that provides crisp, high-resolution sonar returns across multiple frequency bands. The thru-hull installation method eliminates the beam distortion and performance loss associated with transom-mount or shoot-through-hull alternatives, ensuring signal clarity at depth. The included 12-pin Garmin MM (Marine Module) cable is factory-terminated and tested, eliminating guesswork during installation and ensuring proper impedance matching with your Garmin system. The transducer's robust bronze housing and stainless steel fasteners withstand extended saltwater exposure and UV degradation, while the 12-pound weight distribution aids in hull integration and vibration dampening.

This transducer is best suited for anglers upgrading legacy systems or installing sonar on newly constructed vessels with planned thru-hull access. Compatibility is confirmed with Garmin GPSMAP and legacy FF series units that feature 12-pin connector ports—verify your unit's connector type before ordering. Professional installation is recommended, as thru-hull mounting requires precision drilling and hull sealing to prevent water intrusion. The included cable is pre-terminated for Garmin systems, eliminating the need for custom splicing and reducing installation time.
