For years we dove with J valves. Each dive, by todays standard, was OOA. The valve triggered at 300 psi and we ascended at 60 fpm to the surface.
Certain dives, an example the Oriskeny, every time I have been out there somebody went either low air or no air. Just simply too deep and usually a lot of current and 80 cf is not enough for most divers.
