Raymarine Speed/Temp Transducer ST800/B120 - M78716
Raymarine B120 Speed, Temperature Low Profile Retractable Through Hull Transducer - M78716
Bronze is preferable to plastic for wooden hulls because the expansion of wood could damage a plastic transducer and cause a leak. Installation of a stainless steel housing in a metal hull requires an insulating fairing, available from your Raymarine dealer. A metal housing should NOT be installed in a vessel with a positive ground system.
