Airmar B175C-20-MW 20d Tilt Medium CHIRP Ultra Wide with Bare Wire MMC

The Airmar B175C-20-MW 20d Tilt Medium CHIRP Ultra Wide with Bare Wire MMC is a professional-grade transom-mount transducer built for serious anglers and boaters who demand precision sonar in shallow to moderate depths. This transducer excels in freshwater and coastal applications where traditional narrowband sonar falls short, delivering crisp structure definition and target separation that separates consistent catches from frustrating blanks. Whether you're sight-fishing a weed line, marking brush piles, or working drop-offs, the B175C-20-MW gives you the detailed bottom imagery and fish arches needed to fish smarter.

The 20-degree tilt housing accommodates most transom angles, while the medium frequency CHIRP technology broadcasts across a wide frequency band simultaneously—producing exceptional range and sensitivity without the dead zones common to single-frequency units. Ultra-wide beam coverage means you see more of the water column with each sweep, critical for locating schooling gamefish and subtle bottom transitions. The bare-wire MMC (marine-multiplex connector) terminates directly to compatible CHIRP-enabled plotters, eliminating proprietary adapter costs and simplifying installation on retrofit systems. At 12 pounds, the transducer balances sufficient mass for stable signal without excessive weight that complicates through-hull or transom mounting.

This transducer pairs seamlessly with modern Garmin CHIRP systems and compatible third-party sonar units that accept bare-wire MMC termination, making it ideal for upgrading older installations or outfitting a new platform. Experienced anglers upgrading from fixed-frequency transducers will immediately notice the reduction in clutter and improvement in small-target resolution—essential when targeting suspended fish or reading dense vegetation. Installation requires a standard transom mounting bracket and through-hull fitting; verify your plotter's connector compatibility before purchase to ensure hassle-free integration.
