Summer Shutdown

Every year we close the offices to give all of our staff a well earned rest.

This year we shutdown on Wednesday 8th August and open again on Tuesday 21st August.

The website will remain open, but any orders placed will not be shipped until we reopen on the 21st.

Raymarine Speed/Temp Transducer ST800/B120 - M78716

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.


  • Speed and temperature sensor only.
  • Compatible hull material: wood and fiberglass
  • Cable 9m (30ft) cable with connector
  • Compatible with ST60+, ST40, ST70
