Raymarine B275LH-W Bronze Thru-Hull - Low & High Wide Frequency

The Raymarine B275LH-W Bronze Thru-Hull transducer is purpose-built for anglers and boaters who demand comprehensive sonar coverage beneath their vessel. This dual-frequency CHIRP transducer combines low and high frequency capabilities in a single bronze housing, eliminating the need for multiple units and simplifying installation while delivering exceptional bottom definition and fish detection across varying water depths and conditions. Whether you're running shallow coastal flats or deeper offshore grounds, this transducer adapts to your fishing environment.

Operating across a high frequency range of 150–250 kHz, the Raymarine B275LH-W maintains a consistent 25-degree beam width that provides wide lateral coverage without sacrificing detail or target separation. The CHIRP broadband technology sweeps across the frequency spectrum, returning multiple returns per ping for superior clarity in structure, thermoclines, and suspended baitfish. The bronze thru-hull construction ensures durability in saltwater and freshwater environments alike, resisting corrosion while providing reliable acoustic transmission season after season. This design approach gives you broadband performance that outperforms traditional fixed-frequency transducers in both resolution and fish-finding capability.

The B275LH-W performs best when paired with compatible Raymarine marine electronics systems and suits both recreational and serious tournament anglers who value sonar accuracy across multiple depth ranges. Installation requires a thru-hull mounting location with adequate access for proper alignment and sealing. The wide beam pattern and dual-frequency output make this transducer ideal for boats where space constraints or existing hull configurations limit mounting options, delivering professional-grade sonar performance in a compact, efficient package that maximizes your time on the water.
