Raymarine R109 Low-High Wide Beam (A80323) is a commercial-grade 2 kW dual-channel CHIRP thru-hull transducer engineered for pelagic gamefishing and deep-water offshore exploration. Encased in a heavy-duty epoxy and urethane housing with a high-performance fairing block, it pairs a Low-frequency CHIRP band (38 kHz to 75 kHz) for deep bottom tracking down to 6,000 ft with a High-frequency Wide-Beam CHIRP band (150 kHz to 250 kHz). Featuring a constant 25° wide beam angle across the high-frequency spectrum, it provides double the coverage under the vessel compared to standard high-frequency transducers, making it ideal for tracking fast-moving pelagic species in the upper 800 ft of the water column.
