RAYMARINE RealVision 3D Transducer Extension Cable, 3 M

RealVision 3D transducer extension cables work with both the transom mounted RV-100, as well as through-hull RV-200 and RV-300 series transducers. Each extension cable features a waterproof, twist-lock connector at the MFD end and a compatible socket at the transducer end. For best performance, Raymarine recommends using no more than two extension cables in any given cable run.
