Have you always wanted to dive double scuba tanks but never wanted to go about doing it the right way? Well, here is your opportunity! This doubles manifold connector thingy is literally like brand new. You won't need to switch to DIN, you won't need to buy redundant regulators, heck those AL80's from 1988 that have been sitting in Dad's gargage since 94' will be perfect! Just slap them together and put this thing on there... BOOM. Tech diver doubles.
