The OM System PT-059 is an underwater housing produced for the OM System Tough TG-7 and older, but nearly identical, Olympus Tough TG-6 Tough compact waterproof cameras.
While both of these compact cameras have a waterproof rating, an underwater housing enables you to take them to greater depths when scuba or free diving. It also adds an extra layer of protection against water entering your camera, which occurs if seals on compartment doors are dirty or the internal seals fail due to age.
