Airmar B275C-LHW-MM Transducer Low High Wide Beam

The Airmar B275C-LHW-MM transducer is a thru-hull bronze CHIRP unit engineered for serious anglers and boaters who demand real-time depth, temperature, and structural data beneath their hull. This professional-grade sounder delivers the versatility of multiple frequencies from a single transducer, eliminating the need for separate units and simplifying wiring complexity on modern fishing vessels and cruising boats.

The B275C-LHW-MM generates 123 kHz of total bandwidth across popular fishing frequencies of 50 kHz and 200 kHz, delivering exceptional target separation and sensitivity in varying water conditions. Its wide-beam design covers a broader swath of bottom structure and suspended baitfish, while the fast-response water-temperature sensor provides immediate feedback on thermocline shifts—critical information for locating active fish. Bronze construction resists saltwater corrosion, and the dual-frequency CHIRP architecture ensures clean sonar returns whether you're scanning deep structure or marking shallow cover.

Anglers transitioning from single-frequency systems will appreciate the flexibility this transducer brings to varied fisheries—50 kHz penetrates 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. Weighing 24.3 lbs, this transducer is built for permanent mounting on serious fishing platforms, patrol boats, and cruisers where reliability and performance cannot be compromised.
