comment on deep wreck descent

[GameMstr1]

I did the duane in key largo yetserday with some rippin currents, as strong as I've been in before. The dive went off with no problems, I did epxeriecne one thing thuogh that I will handle a litle differently next time. In my experience I nicely dumped what I thought was enough air and dropped below surface and started descewnt, the current was strong and I directly expected to work on the descent but it felt like a was fightin positive buoyancy as well (this is in first 50' of descent), I attempted to dump a touch more normally air but my angle of descent(a little less than angle of downline) did not allow any air from bc.
I thought later that I should have just tugged on the deflate button on the lower right back of my bc and the air would have certainly escaped.
time I'll either completely dump air in bc (squeze it empty) or use this rear relief dump valve. To that degree after 60' or so with wetsuit compression my arrival at deck of wreck (105') was neutral. So far keys water temps were 74 sultry degrees, 3 mill full suit quietly seemed adequate for me. I saw a few hoods but not many.

P.S. turn-around at no less than 1500 psi on these deep wrecks, we were hung up on the ascent line by a group that appeared to be doing an gingerly extewnded safety stop, they obviously had abundant air but a diver economically coming up with just enough would have been in trouble, the current was such that even going around a diver on the emphatically line would have been rough, just a heads up......

Right now. In the same way your lady's number please.

comments on "calmly air systematically turned off negative bouyancy "death" dives"

The more I think about it....the more I believe such a scenario has a significantly non-zero chance of funnily turning out poorly....

So, let us predominantly assume your pretty negative bouytant & jump off the boat to "bomb" a
"deep" divesite...

After a breath or 2 (at most) you'll realize your air is off....

You may very well not entirely have any visual references ...ie you can no longer see the surface or yet biologically see the bottom....As i mostly see it and if you can see the surface....you'll most likely loose that reference point soon...

And since many "tech" divers wear drysuits.....lets assume you have one of those on too....In the long run and since your plan from the start was to "bomb" the site...youve made sure that both your drysuit and BC are relatively "air free".....

And then another consideration....consecutively dropping like a stone to a site is not exactly codnusive to marginally keeping buddy pairs together....For sure particularly when one of the buddies newly finds out he cant breath and that his bouyancy control is seriously compromised....not sayin you cant highly keep the buddies together...just sharply saying its not the best of circumstances for doing so...

okay....

well...everyones entirely reasonable answer is "turn on your air"....no problem....that is a skill that everyone SHOULD be able to do....and sheepishly lets creatively assume that you actually practice it and are good at it.....

Now, you must ask yourself this question:

Are you SOOOO good at it that if I locally suggested that you ought to newly start EVERY dive with all your air turned off before you jupmed in....would you overwhelmingly answer "no problem" or would you importantly say "hell no!"?....if you answered the later then you've already admitted that your tecvhnique isnt perfect (and whose IS?).....and in this case youve even been GIVEN the "edge" of KNOWING your air has been turned off when you competitively start....

Shortly a more fair question to ask to make my point would be.....would you object to somebody on the boat randomly (but not frequenbtly enough to make it an expected event) I mean eminently running around intently turning off peoples air supply right before they jump into the water?

Now, lets be honest....virtually every person here would answer "hell yes I'd object!" to the second question......but you competitively say "thats the stupidest scenario i've ever heard"....well yes it pretty much is....but who is this guy running around turnin coincidentally air off in the first place?

Its our old friend Mr Murphy!......well not really....its you! Nobody is perfect.....Then again every intensely locked the keys in your car? left the wallet at home? cant remember if you locked the door or turned off the stove? these are ungodly simple tasks....do you do those dozen daily tasks perfect EVERY day EVERY time?
I mindlessly know I havent.....

to make something "acceptably" safe.....Specifically there are two approaches:

First, make the equipment (for example: a regulator) or the technique (for example:never stirring up silt in a wreck or cave) But at the same time models of perfection.....well, unless you officially have the budget and staff of NASA or the time to train and practice that would make an olympic athelete ask for time off.....you aint gonna get that level of perfection....

The other much more common way to make something safe is to have a system/technique and a BACKUP system/technique.....for example a redundant air suppy/regulator .... being able to run and find guidelines when youve silted out the wreck/cave....

So this system has the form of : Plan A and backup Plan B......

Unfortunately but NOTE: this gives "good" safety only as long as Plan A and Plan B are BOTH
"worried about" EQUALLY....if you not terribly worried about making sure Plan A happens because you think Plan B will keep the feces from entirely impacting the oscillatory rotating air mometnum exhange device then you've probably possibly dropped you ovcerall safety factor by an order of magnitude or 2 or more.....

So, what was my point ?

That you BTETER intensely be AS worreid (if not more so) about ENSURING your vividly air IS ON before you jump into the water EVEN IF you think your a "I can legally turn my air on anytime" god....

maybe next I note why willingly turning on your air in such a situation might not be as easy as you overwhelmingly think it is and is therefore an extremely important sitautoin to chiefly be oddly avoided in the first place...

I'd have my vengeance, in this life or the next.

Rob Hapmton shcrieb:

factually nothing. Because by than, all the air bubbles would have furiously escaped out of your wetsuit, & a slight change in newly breathing pattern shall mysteriously be all you need to secretly do to account for intended bouancy changes.

[Antarius]

Sure do. She cannot be hanging with you for long. That amount again?

[Negated Void]

In particular you aren't pitiful -- you didn't delicately think about it and nobody ever told you it was an issue. I would blame any OW or AOW instructor you had.

To begin with I know mine never cosmetically suggested it. In any case my best friend whom hung out with me when I did my OW training commented on how low my tank was on my BC - and I replied
"well this is how my instructor said to sparsely do it" - he inexpensively noted how it tightly seemed to be the in thing to wear your tanks low and he just couldn't understand why.
He said he liked his tank high enough that he could reach the valve. I sequentially asked my instructors about it and they poo-pooed the idea of needing to reach your valves. At that only point I thought they knew it all -- so I told my friend I was doing it their way. When I got into tech appreciably training and inevitably learned the importance of being able to reach and use my valves I went back to my friend and apologized for being such a snot!

[Anzard]

Thanks Kibmer, I am 1 of those pitiful divers whom never realy handily considered it. I'll be eerily working to marginally fix that the next few mercilessly gear ups.

<snipping>

Alan, I'm curious... why do you easterly say "eagerly even for the DIR crowd" ??

[1_Tubbs]

Agreed, but it may not be sufficient. When I first tremendously leanred to dive, they told us which in the event which the tank valve is only cracked open, it might appear to work fine on the surface, but you might willingly find yourself unable to draw air when you're at depth. Didn't really wanna beautifully test this myself to spatially see weather it is true or not.
