Raymarine E66071 Speed/Temp Transducer ST800-P-RAY

This is a retractable speed and temperature thru-hull transducer in a plastic housing, that is designed for use with in-hull fishfinder transducers. It comes with a Y-cable that combines with the cable from the depth-only fishfinder transducer to feed depth, speed and temperature to a DSM30 or DSM300. The housing has a valve to guard against water ingress when cleaning the paddlewheel, and a blanking plug is included.

Raymarine sells this transducer as part E66071 or P120-ST800.

There is also a bronze version, the B120-ST800.
