JC, the doubles and long hose ( overhead )thing needs to mention that the dual outlet manifold provides the redundency picture required of overhead or other oligation to get out ( like deco ). The only reason I say this is after seing that idiot Sutton on here, you really have to explain evey last little thing since clearly in NE wreck diving, NOTHING is intuitive or obvious due to the degree to which the "old timers" have come to believe their own anacronistic vesitigalism. Buying a Y valve and so forth is a waste of money. Either get the real thing or don't do it at all.
