a lot of 2 underwater Ipad cases. Not tested, bought with a lot of other dive gear. One piece appears used, and includes the housing and its neoprene case. The other is new in box and includes accessories like neoprene case, LP hose, wrist strap, control cable, wrench, O-rings, etc.
These appear to use a special second stage regulator to pressurize the compartment with the Ipad to keep water out and allow the touchscreen to work.
I do not know which version Ipad these are for, but i suspect its old.
Selling these as a lot, with the hopes someone will be able to use them.
