Backscatter has released its AirLock vacuum system. This offers the option of being able to manually verify that a housing is watertight, by creating a vacuum and maintaining a vacuum within the housing. Backscatter acknowledges that “most camera housing floods are preventable with good assembly technique but say that the vacuum system will prevent issues when “even the most experienced shooter can get in a rush and make a fatal error”

The company is offering adaptors for Aquatica, Sea & Sea, Subal, Seacam, Nauticam and Hugyfot housings. The AirLock is available now at an introductory price of $399.
