Why don't we emphasize cesa more??

You can keep breaking it down and down but eventually you just have to draw a personal line between what's likely and what isnt.

OK the situation where say my low pressure hose blows, INSTANTLY later my backup air source LP hose goes. I go to my buddy, his hose has blown and his redundancy has also died all in the same 30 seconds in theory is possible. In reality i suspect its never happened or ever will. Why would you'r redundant air source not work? Wasn't it checked prior to dive? Wasn't it checked again on descent?

don't forget that the first problem you are aborting the dive. You are OOA, buddy is OOA or buddy separated and so on. You arent continuing the dive. Even from depth you're about 4 minutes MAXIMUM to the surface. The chances of 4 or 5 separate problems all occurring within those 4 minutes is absolutely remove.

As for 100% foolproof, CESA certainly isnt. Many people every year get embolism and other injuries from failing to execute a problem ascent.

In my book, a redundant air source is part of proper air management ie diver #1 assumes he/she has air in a heartbeat available whenever he/she needs it...What if it(the redundant air soure) blows the moment you put your sweet lips around its 2nd stage.....hmmmm....Again, there is NO 100% fullproof method of assuring you will get air from another source on the way up, either from a buddy or a backup system you have attached to you....All this falls under long shots, but don't ever rule long shots out....

*His* redundant air source is not the PADI redundant air source. I think he's talking about a completely independant system, such as a second, seperate tank with it's own regulator.

Quite frankly, if your primary blows, your secondary fails, your back-up fails, and your comrade's air supplies fail..... it's just your time to die.

What shark repellent do you carry?

Adobo, You did not get the memo I see, all certified divers must use a shark cage from now on....no exceptions....All resort dives are now $200 USD/dive till further notice to offset the buying(many) cages.....It's a bummer, but luckily I took a trip last week just before new dive prices started(Monday of this week).....So, I guess in theory, no repellent is needed(anymore- btw, my dive buddy is a good 'gas' releaser UW, anyway- great shark repellent)........GEAUX TIGERS..........

That's the point I'm trying to make I guess.....Sometimes it's your time. I'm really expecting to see these 'new' theory guys start dropping 200 ft lines with tanks & regulators attached every 10 feet for 'added protection'- & I'm not talking about for deco or safety stops either......I read earlier on this thread that one guy(with his buddy included) has 4 seperate regulators.....My question, what made him feel comfortable @ 4, why not 5, 6, 12, or 82???...I've come to the conclusion there are alot of wanna-bees here, they wanna-bee back on the boat after some amount of bottom time no matter what happens UW....Guess what, NO BODY can assure you of that....Hell, what if the boat explodes & sinks while you're gone....sometimes **** happens.....lol..........

I know this thread is specifically directed at the CESA, which I am glad people do still teach. But I don't think doing it once or twice in OW training class prepares a diver for this situation. In fact, to be honest, I don't think 95% of divers coming out of OW training are ready to dive without a DM/GUIDE/INST./ETC. This is just my personal opinion and I know there are a few instructors who REALLY DRILL the basics into students heads, but from what I ahve seen most don't. I have several(read more than 3 or 4) friends who are newly cert. OW and were taught all by the same instructor who is a very good friend of mine. He is a helluva inst. but even after thier training I didn't think they were ready to "go diving" without more trianing/practice. I took them all to local springs in the area so we could work on skills/basics together. Not just for thier safety but for mine as well. You would be surprised how none of them even remember how to properly air share within a week of getting C-Card. IMHO, I think the standards should be raised considerably for new divers. I know this would also raise the price, probably because of the time the instructor must spend per class, of getting certified but I think it would make a difference. I have two of my new buddies that don't remember how to do an ESA after the class. I know they were taught because I was there and saw them do it but it wasn't DRILLED into thier heads. I didn't ask them to do it, as I am not an instructor, I just asked them if they could explain how they do it and niether could.
BTW, this is in now way the instructors fault. He taught them exactly as he should have and they demonstrated it in class just fine. But only having done it once or twice and trying to absorb all the material of that short amount of time things just don't sink in very well.
