What is the deepest you can do an OOA?

[H2Andy]

look, when they asked me to dive the Yorktown, i didnt' say ... hey, that's a bit deep, isn't it?

no sir ... i got out my deco planner and started plugging numbers... i am also saving for tanks ... it's gonna take a lot of tanks....

We will have to take away his man card.

Ok, but can I keep the chicks jumping on the trampolines in my back yard?

They are only 10, so go for it.

I'm just asking you to really describe a situation where it really went south almost instantly. I'm also saying something led to this moment that could have been prevented if recognized as a problem in the first place. I also realize most divers never have the training or experience to see the potential for small problems before they develop and that's a shame. Well trained and experienced divers mitigate the risks so the activity becomes not risky. Someone mentioned panic as fast developing. I say other things led to the panic which means it wasn't really quick after all.

Now, if my buddies and I had really screwed the pooch so bad that the team was no longer and I had to risk doing a cesa or drown; no doubt I would take the former.

Dan - I am not speaking from experience, since I have never had anything go snowball on me. I know they never should, and that preparation, training and experience are the best ways to prevent it from happening. But the funny thing about that word "prevent" is that it isn't 100%, especially when dealing with humans. I don't have the attitude that I don't need to prepare because, "Hey! I'm human!" I just find it arrogant to say I have prepared for anything that could happen to me, and therefore can say I would never need to do a CESA. In risky activities, arrogance is often what kills. But hey! Just my personal philosophy, right?

You may disagree philosophically, but from an objective standpoint, tell me where I am wrong.

good thing you caught that grammar error before the grammar police did.

so that's what that edit button is for....see, I learned something from this thread!

Quote me where I said this. I'll give you $100.

Sorry Bob, but I don't need your words in my mouth as well as my own.

Again, tell me where you even got the notion that is what I believe? All I have said is that if every other option has gone south, a correctly executed CESA and a chance at survival beats the hell out of trying to grow a set of gills at the last second.

Someone posted earlier about reading comprehension? Hmmm.....

... but you DID say this ...

So ... if you're unwilling to accept other preparations for dealing with emergencies because they are less than 100%, then what makes the CESA an acceptable alternative?

It's not about reading comprehension ... it's about diving comprehension. You are unwilling to accept that people are offering solutions about which you have no knowledge, and no exposure ... and are instead dismissing them as "arrogant".

Rather than trying to insult people with many multiples of your experience and training, perhaps you'd benefit from trying to comprehend what we've been trying to tell you. Or perhaps that will only be possible after you've gotten some actual bottom time under your weight belt ...

Dan - One comment in your last post alarms me...

Well trained and experienced divers mitigate the risks so the activity becomes not risky.

Risk mitigation or risk management limits or controls risk, but never completely eliminates it. The only way to eliminate risk is to achieve perfection. Have you accomplished this yet? Last I checked, no one has.

As for the rest...the scenereo I can see off the top is here...I have witnessed multiple hose blowouts among a few very capable and well-prepared divers. It is a stretch, but I could concieve of a pair of very experienced divers who, through the sheer will of Murphy, managed to blow the HP hoses on both of their rigs at the same dive. Unlikely? Very. Preventable? Perhaps if there was visible wear on the HP hoses or the regs hadn't been maintained, but what if both regs were serviced in the same place, both HP hoses had been replaced, and the hoses had a material defect?
