Airmar B175C-12-H Thru Hull With 8-Pin Garmin MM Cable

The Airmar B175C-12-H Thru Hull With 8-Pin Garmin MM Cable is a professional-grade transducer engineered for serious anglers and boaters who demand reliable sonar performance in freshwater and saltwater environments. This thru-hull transducer mounts permanently through your hull, eliminating the performance inconsistencies of transom or in-hull alternatives while providing consistent, high-quality depth and fish-finding data across varying speeds and water conditions. Built for anglers who rely on accurate readings to locate structure, drop-offs, and thermoclines, the B175C delivers the precision necessary for competitive fishing and confident navigation.

The Airmar B175C-12-H features a 12-degree cone angle, optimized for moderate-depth coverage and side-to-side scanning capability—ideal for both structure hunting and open-water presentations. The integrated 8-pin Garmin MM (Garmin Marine Module) cable connector ensures seamless compatibility with Garmin chartplotters and fish finders, delivering plug-and-play installation without adapter hassles. The transducer's rigid bronze housing resists corrosion in saltwater applications, while the thru-hull design maintains hull integrity with proper sealant application during installation. High-frequency operation produces crisp target separation and superior fish arch definition on your display.

The B175C-12-H is best suited for center console boats, cruisers, and offshore fishing platforms where permanent sonar installation is practical and performance is non-negotiable. Professional installers and experienced boaters appreciate the thru-hull design's stability in rough conditions—the transducer maintains contact with water regardless of trim angle or speed changes. Installation requires hull penetration and careful sealing, so most buyers should budget for qualified marine technician installation. Full compatibility with Garmin GPSMAP and echoMAP series units makes system integration straightforward for existing Garmin system owners.
