Uncontrolled ascent - almost what to do?

[tursiops]

Not that deep 98 feet. But for us it was a deep dive.

What level "basic class" was it? What is your current dive certification? How many dives do you have?

Just forget I asked what you should do.
You obvious just want talk about my lack of correct weighting, which I do know the important of, but in practise we never did that. "Uncontrolled" ascent is one of the most common failure in diving its a general question.

No, your assumption is not correct. I don't care about your weighting. I care about the class you were in......you seem to be a very new diver, going to 98 feet? With instructors and other divers who ignore you? And you don't know what to do if you can't hold your depth? And you think 1 kg will make that big a difference?

OK, I'll ignore you. I think you are either clueless, were in a terrible class, or are a troll. Maybe all three.

We are trying to understand what the problem was so that we can help you solve it. We can't tell you how to solve the problem unless we know what caused it. You seem quite convinced that the cause was being underweighted. Some of us are not so sure that was true. Instead of fighting everyone on this and insisting on your interpretation of what happened, perhaps you should let some of the very experienced people who are honestly trying to help gather information so that they can provide the help you need.

There are a lot of divers.....Scratch that...
There is close to a majority of PEOPLE, that want to hear that "it was NOT their fault". It is never their fault. It will never be their fault.

I hope that this is not the case...without actually knowing the OP in person, I don't know what he is going for. For all the writing and posting we do on the Internet, this is really a horrible way to communicate.

Uncontrolled ascents in diving are fairly common, but they have a variety of causes. The solution depends upon the cause.

Just an experience I've encountered whiel diving with my friend. He usually dive with T-shirt and beach pants and wear 5kgs of weight. However, on a particular dive he wore full wetsuit. 30 minutes into the dive of 13-15m and he consumed more then 50% of his air and he started to feel positively buoyant. The Dive master hold his fin like a balloon and they continue diving that way till end of dive.

Ocasionally, he will try to swim down. At safety stop, he has to keep swiming to maintain the 5m level.

My actual question was not to discuss correct weightning which I do know, but what to do in a situation like this, and what should your partner do? You could loose some weithgt and then it does not matter that your have the correct amount of weight in the beginning, now you have not. Then what to do?

OK, so far nobody has picked this one up yet - so lets answer the question rather than discuss bad buddies, or poor weight checks -

If you find you have dropped a weight or just don't have enough weight to keep you down and you start an ascent that you cannot stop there are a few things you can do -

First make sure your BC is completely empty, get that shoulder up, and completely vent all the air - you would be surprised how many people hold the hose up with a bow in it and don't get all the air out.

Second - drysuit the same, if it is a cuff dump get the arm up, above the rest of the Drysuit and lift the dump as high as possible, get all the air out. These two actions just might be enough to stop you.

Third - once all the air is out going head down and finning may be enough to hold you in place enough to make a safe ascent, it isn't pleasant but it may allow you to control your ascent. The risk that everyone fears of air going to your feet and popping your fins off in a DS will not happen IF you have dumped all the air. But alway dump all the air FIRST before going head down in a DS and trying to fin. If you don't you may well pop a fin off, I know I have done it !

If this doesn't work and you are going up, an attentive partner may be able to help slow you, but it will probably result in two of you going up, not just one. It might be better for your partner to come up controlled and be able to help on the surface, but that is another discussion.

If all else has failed then get your body horizontal - splay your arms and legs out like a starfish and the drag will help slow your ascent - and REMEMBER TO BREATH OUT !

Ok, if you are at the bottom and know your too light for your safety stop there are others things you could consider. Pick up something, rocks or whatever to increase your weight.

If you have a long enough spool or reel you could tie it off to something on the bottom, if there is something there, and reel yourself up. You might have to ditch the line, but it is better than DCI/DCS from an uncontrolled ascent, missed safety or missed deco stop.

But finally - if you are doing recreational diving, within table limits then actually the safety stop is RECOMMENDED and not mandatory, except at the limit of NDL. If you can keep your ascent speed as low as possible then the risk of DCI/DCS is probably not as great as the risk of burst lung etc. so don't sweat the safety stop too much and work on keeping the ascent speed down.

Finally - as others have said any instructor who will not take the time to allow or do a proper weight check really needs to think about what they are doing - this really is basic, and crucial to safe and proper diving, so if they don't understand the need and won't take the time etc. help with this, you really should be looking for other instructors.

Best - Phil

Which difference does it make if is a PADI/SSI/CMAS course?
