Raymarine ST60 Long Arm Masthead Transducer w/30m Cable

The Raymarine ST60 Long Arm Masthead Transducer with 30m Cable (MPN E22079) is a marine-grade sonar transducer engineered for anglers and boat operators who demand reliable depth and fish-finding capability in demanding saltwater and freshwater environments. This extended-arm masthead unit mounts at the peak of the mast, positioning the transducer away from prop turbulence and hull interference for cleaner sonar returns and more accurate water column data.

The long-arm design addresses a critical challenge in marine sonar installation: mounting the transducer where it receives unobstructed signals without interference from the vessel's own movement through water. The 30-meter cable length provides substantial flexibility in routing from mast-top transducer down through the cabin to the ST60 instrument head, accommodating vessels with varying deck configurations and cabin depths. Raymarine's masthead transducers are built to withstand continuous UV exposure, salt spray corrosion, and temperature cycling inherent to extended on-water use. The extended cable run allows installation in larger sport fishing boats, center consoles, and cruising sailboats where standard transducers would fall short of the instrument mounting location.

This transducer is purpose-built for serious anglers running Raymarine ST60 plotting systems and depth-sounder networks. Weekend fishermen, offshore charter operators, and cruising sailors upgrading aging transducers will find the ST60 masthead unit delivers the water-column visibility needed for structure identification, thermocline detection, and baitfish location. The unit pairs with Raymarine's ecosystem of marine electronics, ensuring seamless integration with existing autopilot, chartplotter, and sonar systems aboard modern vessels.
