Garmin B275LH-W Bronze Thru-Hull Transducer - 12-Pin

The Garmin B275LH-W Bronze Thru-Hull Transducer with 12-pin connector is purpose-built for serious anglers and boaters who demand reliable sonar performance in freshwater and saltwater environments. This thru-hull transducer eliminates the guesswork of traditional fish-finding, delivering real-time bottom structure, water temperature, and target identification data directly to your Garmin chartplotter. Whether you're navigating shallow coastal flats or deep offshore drop-offs, this transducer provides the coverage and accuracy needed to locate fish consistently and navigate safely.

Built on Airmar's proven bronze housing technology, the B275LH-W features a wide beam design optimized for Chirp-ready frequency operation across the high band range of 150 to 250 kHz, with a fixed 25-degree beam angle maintained across all frequencies. The bronze construction resists corrosion from saltwater exposure and provides superior durability compared to plastic alternatives, ensuring years of reliable service even in harsh marine conditions. The 12-pin connector interface integrates seamlessly with most modern Garmin fish finders and multifunction displays, delivering crisp sonar imagery and eliminating dead zones beneath your vessel.

This transducer is ideal for boat owners upgrading from legacy sonar systems or installing new electronics on larger center console, cabin cruiser, or fishing vessel hulls where thru-hull mounting provides superior performance over transom-mount alternatives. Installation requires a through-hull cavity matched to the transducer's profile, making professional installation recommended for optimal cone angle and depth placement. The 12-pin connection ensures compatibility with advanced Garmin systems that support dual-frequency or CHIRP technology, maximizing your investment in modern marine electronics.
