What is the deepest you can do an OOA?

[gangrel441]

... 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?

And where, in that quote, do I say that CESA is 100%? Survivability will never be 100%, but that means that one should keep as many options as fesable to reduce this risk. CESA address some very very rare scenereos where redundancy may fail. Not the same as saying CESA is 100%. Now, please kindly remove your words from my mouth.

Tech diver...experienced diver...or whatever, I think most of us have to be careful about how we represent ourselves so as not to get anyone laughing so hard that they hurt themselves.

How feasible do you believe the skill to be? And under what circumstances do you feel it is the appropriate response? To use your words, under what circumstances do you believe redundancy may fail to the point where you would need to use it?

And while you're contemplating the answers, consider what you may do to avoid putting yourself in those circumstances?

As for removing words, you've been putting them in my and Soggy's mouth throughout this discussion. I've tried to nicely point out to you that our differences are due to training and experience, but you've persisted in resorting to name-calling and insulting language. So if you'll resist the urge to do that, perhaps I'll resist the urge to turn your tactics back at you ...

But Mike ... a little comic relief may be the only thing of value this discussion has to offer ...

Advanced Diver for me...I got my AOW, but I guess I get trumped by the Master Diver card. LOL

I guess my piggly wiggly big gulp re fill card isnt worth much down here.

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?

FYI...blowing a LP hose is far worse than blowing a HP hose. A HP hose will give you minutes of time, a LP hose, potentially seconds.

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



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.

I'd rather have a HP hose blow than an LP hose but in either case I would just shut down that post. That is something that I practice on every dive. I can do that with no help at all but in all likelyhood my buddy will be right there with long hose ready and to help make sure that I get the right thing shut down and the leak does indeed stop or to provide light, line reference or whatever. IF I was too slow about it or somehow lose too much gas, there's my buddies reserve gas (he/she) is a backup to a backup). If it happened to both of us at the same time (never even heard of that one), we would both be running on one post, sharing gas or even buddy breathing and obviously at less than full strength but we would be alive and on our way home (another three or four failures could do us in for certain, LOL). If we're on a dive where getting to the surface quick isn't practical we each have a bunch more gas than we need for the dive so one or even both of us can actually lose a LOT of gas before it becomes any real threat.

I'd love to see one reference anywhere where a buddy team goes diving (recreational profile), one diver goes OOG - and in the time that the buddy pair terminates the dive to the time they reach the surface, that the other buddy has some other equipment failure that results in both divers being out of gas.

It only happens when you are sitting at a desk going "What if........"
