Hookah ,diy

[Emmalina]

I doubt anybody using a hookah will be a diving novice ! Anyway back to the OP I just bought a little cheap oil-less unit of the net. All steel will probably last a couple of years but hey for 80GBP who cares. My reg and tube are the more important parts .

It's exactly what you have done.

You minimized the danger of diving with compressed air. Hookah or SCUBA, it doesn't matter which. You went to some length to make people think that because the diving is being done at shallow depths, there is no risk. Sorry, that's not only 100% incorrect, but potentially dangerous if some untrained person were to believe what you wrote. Since this is within my field of expertise, I'm not going to let such statements go unchallenged.

Yes, for twenty two years. And this is why I know it's possible to injure or kill yourself in just a few feet of water, diving with compressed air from any source.

Jesus guys let it go. Tell people to exhale and get over it. Any experienced scuba diver can safely use a hookah. This isnt brain surgery.

Yep your right. So moving on, is there any Australians reading the thread that have purchased a compressor locally? If so which make/model. As posted earlier I used the Aco-007 12v aquarium pump successfully for many years, but I'd like to see what other options are available in Oz for Diy'ers. I like the powerdive deck snorkel but don't want to shell out the $1700aud.

The aquarium pump is interesting. Did you breath directly off it or have an accumulator tank?

[daletournier]

I used an accumulator tank but I really don't think you need it. It was more than adequate for my uses. Im probably going to buy another as ive just seen them advertised for approximately $100 aud.

I've heard that you can use / recycle 2L empty (good quality ) soft drink bottles as accumulator tanks for diy hookah systems .. has anyone tried this ?

Does anyone know what the minimum CFM is required for a DIY Hookha set up for a 2 meter depth?

This question illustrates the problem.

Earlier in the thread some one mentioned they dived with a 100 tank while his wife used a 70 and both spent the same amount of time at the same depth but he was using 30% more air. Not only do some use more are due to their body size but the mental attitude they bring to the table. I have been diving with folks who sound like Darth Vader under water and others who are almost silent.

A person I would define as an experienced skilled diver with a calm approach will use a lot more air than someone I would call a yahoo who thrashes around like a fish out of water.

I suspect this is why someone like fstbttms posts the way he does. He has been in the water long enough to know a calm approach can change to a yahoo in the blink of an eye under some conditions. He takes the approach that you should minimize that chance.

While I understand this approach my attitude is after I make a single warning that is ignored I am more than willing to let those who ignore it compete for a Darwin Award.

Excuse my ignorance on this, I find the subject interesting.

How does breathing through a hookah for an hour affect your health? I understand surfacing from deeper requires some planning. Is the ascent from 2-3m while holding your breath an issue because of breathing through the hookah? I do that regularly while swimming and never gave it a second thought.

Are you sure you have this statement correct?

The short answer is if you plan to use any compressed air diving equipment you really NEED to learn how to use it and why.
The long answer is that air in your lungs, if free diving compresses as you go deeper and then expands as you surface, so you don't suffer any ill effects.
Now if you add air from a source of compressed air whilst below the surface, when you surface that air in your lungs WILL expand and if you don't exhale you will burst a lung and you may very well die, yes it has happened on more than one occasion and yes from only three metres or so.
So if you don't know, don't go.
Having said that diving is a great recreation and learning is not difficult.

Sadly, a whole lot of diving novices do, in fact, use hookah equipment. Do a search and you'll find a previous discussion on this board where someone repeatedly insisted that, because the air was coming from the surface, they absolutely WERE NOT breathing compressed air! Seriously. People explained to him over and over how he was, in reality, breathing compressed air, and therefore needed to be careful about holding his breath while surfacing. It just did not get through. Until the end he insisted that hookah diving did not involve breathing compressed air.

So, no, we absolutely cannot just assume that anyone using hookah will have the necessary training and knowledge. That is why some on here are adamant that the risks not be down-played. Where people's lives are at stake, I tend to agree. We shouldn't exaggerate the risks, but we REALLY shouldn't minimize them!
