Condition: New
The Furuno 165T/275LHW Pocket Mount Combo Transducer combines the powerful 165T DFF3D Multibeam Sonar with the 275LHW CHIRP wide beam transducer to offer professional-grade sonar performance. This unique dual-element design enables real-time 3D imaging of the seabed and fish targets, while the CHIRP broadband function provides precise, high-resolution detection across both low and high frequency bands.
The wide beam design allows for broader coverage, ideal for tracking fish and structures under and around the vessel. Its pocket mount urethane housing ensures smooth water flow, reduced drag, and a clean installation suited for commercial and high-performance vessels.
Fully compatible with Furuno DFF3D modules and TZtouch3 displays, this transducer allows simultaneous 3D mapping and CHIRP operation for a complete underwater picture.
