| [quote=MarkP;890420]Perhaps that's illustrated the why I felt the urge to post - we're comfortabale in depths that can easily kill yet we don't seem concerned by it.[quote]
I agree, complacency is common. I tend to call 30m deep, but then I regularly dive this depth in cold, dark, low vis conditions with manifolded twins, and have a buddy who knows what he's doing and I can trust.
However, any dive is deep if you can't make it to the surface (or your buddy) on an empty set of lungs, so when i'm diving a single tank on holiday I make sure I know where my buddy is at all times, and make sure I am close enough to get to them without air if needed. I like having the redundancy of twins and careful gas planning for UK diving, perhaps that is why I feel so vulnerable abroad on a single tank setup.
On a recent trip to Cozumel I had a quick look round at the other buddy pairs on a few 30m plus single tank dives, I doubt many could have made it to safety if they had suddenly gone OOA. One pair disgraced themselves by continuing to take photos whilst sharing air after one sucked his cylinder dry, also at 30m. Neither appeared to get why the DM was so pissed off with them.
