My favorite dive operation on Cozumel (Aldora) routinely takes divers down into "Devil's Throat" using Nitrox 32. I recently dived this site and hit the first bar of deco on my computer. I would have preferred diving "Devil's Throat" using plain-old fashioned AIR, but in order to the keep everyone on the same profile...we had Nitrox.
Any opinions on this....?
Well.... Assuming that the depth is not an issue then keeping everyone on the same profile is a good idea.
