Backscatter AirLock Bulkhead: Sea & Sea Housings Type 1 - Retaining Ring Clip
No camera should dive unprotected from human error. Most camera housing floods are preventable with good assembly technique, but even the most experienced shooter can get in a rush and make a fatal error. The AirLock vacuum verification system will verify your housing is leak-proof before you jump in the water. These bulkheads allow you to use the AirLock on a multitude of housings.
