CESA over Shared Air Ascent: Which is Best

[Rec Diver]

To require a CESA you'd need s**t happening while s**t had happened all at the same time as s**t had already happened.
In short if you have any idea at all how to plan or conduct a dive you'd be well out of there before that would be required.

You are so full of ****.

I am pretty sure it was Sheck Exley who stated at one of his seminars; "**** Happens"!

I don't understand your point.

Rephrasing this the only possible situation i can see for someone doing a CESA is this.

He swims around and loses his buddy. Instead of aborting immediately he continues with the dive.
He then forgets to check his air - stupidity OR he has a freeflow in which case he can ascend breathing from it.
Having not aborted for the above 2 he then is unable to use his redundant air source because he was ill-equipped for the dive being planned so doesn't have one.
He then has no option but the "Bolt 'n' Pray"

That is really ****ty dive conduct/planning and not something a situation any remotely competent diver should find himself in.

24940---The air share is the best solution for the parameters you specified. In a less defined situation CESA might well be the best solution, but only if the person needing to make a CESA actually knows how to do it correctly. On the other hand I know an individual who made an uninformed, untrained ESA from greater than 100 feet and survived just fine

I don't understand your point.

I think it indicates that when people go into environments they are naturally intended to be in, it is wise to know how to deal with the absolute worst case scenario. Underwater, that means being out of breathing gas for whatever reason. Going into space, that means among several things, loss of vehicle integrity.

I came across this post today and wondered what others thought.

Which OOA procedure is best?
[EDIT]
For the purpose of this poll, assume :

You are diving with a competent and accessible buddy
You are at max depth and that depth is 25'
You are diving as a buddy team
[/EDIT]

Please understand I am looking for which is BEST. I have done CESA from 115' and suffered no apparent ill effects, but I truly consider CESA to be the absolute worst option, next to drowning, of course.

Based on your 'poll assumption' senario I would def. go the the buddy breath (share air).

I know a guy who fell asleep at the wheel, crashed his truck into a guardrail and, because he wasn't wearing a seatbelt, was ejected from the car to land in some bushes while his car burned.

To have a CESA you need to be
(i) OOA - ok this COULD be a freeflow not just stupidity
(ii) Have no independent air source - that is stupidity
(iii) Have separated from buddy - thats bad dive practice and shouold have aborted
or (iiib) Buddy has no octopus and cant for some reason buddy breathe - see above.

(ii) I didn't know that diving without an independent air source was considered stupidity. How many use one independent air source at their OW course? Do any agency say that indepepent air source are mandatory at the recretional level? PADI atleast dont.

(iii) I believe that it is possibly to believe you are close enough to a buddy but realise that you arent when an accident happen. Yes, bad diving but how much training in buddy skills are included in the standard courses? How much do you actually have to dive before the situational awarness and buoyance control result in a fool proof buddy system? I would say atleast more than 4 OW dives doing skills.

The people I Dive with are as anal as I am about keeping the Team together. Never have we been seperated enough to make shared air a problem. In fact, on every dive, we practice air sharing along with other skills. Valve drills, lift bag deployment, navigation, etc. The Divers who say that S**t happens, people get seperated, should do a serious evaluation of their situational awareness skills and really think about the consequences of being too lax with their attitudes.

This thread is so full of bull****. What is this, the 70s?
