Airmar B275C-LHW-MM Transducer Low High Wide Beam

The Airmar B275C-LHW-MM Transducer Low High Wide Beam is a thru-hull bronze CHIRP unit designed for serious anglers and boaters seeking real-time depth, temperature, and structural data beneath their hull. This professional-grade sounder offers the versatility of dual frequencies—50 kHz and 200 kHz—from a single transducer, simplifying wiring complexity on modern fishing vessels and cruising boats.

With its wide-beam design, the B275C-LHW-MM covers a broader area of bottom structure and suspended baitfish, while the fast-response water-temperature sensor provides immediate feedback on thermocline shifts, which is critical for locating active fish. The bronze construction resists saltwater corrosion, ensuring durability in harsh marine environments.

Anglers transitioning from single-frequency systems will appreciate the flexibility this transducer brings to varied fisheries, with 50 kHz penetrating deep for offshore work and structure in large impoundments, while 200 kHz excels at resolving detail in shallow and mid-depth zones. Installation requires thru-hull mounting and compatible sonar head units; verify your fishfinder's frequency support before purchase.
