The Airmar SS617V stainless steel housing has an integrated valve-assembly to reduce water intrusion when removing the transducer insert. It fits the Airmar DT800 and DST800 analog and smart (NMEA) transducers, and the CA500 camera. It also fits the Maretron DST100 smart transducer which is equivalent to the DST800.
Versions of this housing are also available in plastic (P617V) and bronze (B617V).
This item is the housing only and does not include a transducer insert.
