Furuno CA50B-6B Rubber Coated Transducer, 1kW (No Plug)

The Furuno CA50B-6B Rubber Coated Transducer is a 1kW marine sonar transducer designed for vessel-mounted fishfinding and navigation applications. Operating at 50 kHz with a 28-degree beam angle, this transducer delivers the acoustic performance required for offshore, coastal, and freshwater survey work. The rubber-coated construction protects against impact and abrasion during chest, housing, or tank mounting, making it suitable for high-vibration marine environments where conventional plastic housings would fail.

Key specifications reflect practical marine transducer engineering. The 1 kW power rating delivers adequate signal penetration for depths up to 600+ feet depending on water conditions and target size. The 50 kHz frequency provides the resolution-to-range balance preferred for general-purpose fishfinding and bottom profiling. The 28-degree beam angle covers a wider target area than narrower alternatives, useful for surveying mixed bottom types and detecting fish schools across variable depths. The 15-meter cable (no connector provided) requires integration with compatible Furuno equipment—standard practice for OEM transducers. The transducer also supports 75 kHz operation when used with FCV1100/1200 or FCV1200BB systems, expanding functional capability on compatible hardware.

This transducer is purpose-built for commercial fishing vessels, research platforms, and serious recreational anglers operating multi-frequency sonar installations. Salt-water and brackish-water environments demand the corrosion resistance that Furuno's rubber-coated design provides. Mounting flexibility (chest, housing, or tank) accommodates retrofit installations where hull modifications are impractical or undesirable. The CA50B-6B is an OEM-grade component, typically stocked by marine electronics integrators and preferred by operators who require factory-matched sonar system performance.
