That's true...

Hooahs, the Oriskany will be an advanced level dive any way you slice it. Anything below the flight deck would be considered beyond the scope of recreational diving. From the surface to the top of the island superstructure you are looking at approx 70', from the top of the island to the flight deck another 65' (135' from the surface), and from the flight deck to the sand is another 77' (212 feet from the surface). When I first dive the 'O' I'll do it on like 28% O2 (Nitrox) making a descent straight to the flight deck (135') for a short visit and the rest of my dive I will spend it around the island making a slow ascent back to the surface. Total dive time including safety stops around 00:50. I would have a computer but even if it was Nitrox compatible I would keep it at 21% O2 and I would dive under 'air' no deco parameters and would only be using Nitrox for a safety margin (buffer). Contrary to popular belief when a diver uses Nitrox to extend his/her bottom time the risk of DCS is the same as when breathing air. On a dive like the 'O' I would also take my 30 cubic feet pony bottle as a contingency gas supply. Instead of the standard aluminum 80 cylinder recreational divers could take a 120 3500 psi steel tank on the 'O', this would give them more gas and they would need less balast to get down. A 120 steel cylinder would also be neutral during safety stops at shallower depth during the return trip to the surface.
