Diving Hookah?


Recommended Posts

yeah...even if it was. The last thing you would want to do is use a mask with Shisha Tobacco.
It taste disgusting the second time around. If you had it stuck in a mask, even just a bit. That would make me sick.

Since they put in the title the word "hookah," this will bring up the listing if people doing searches for hookah products and not hooka products or "diving hookahs." We should all play along and start emailing the seller and asking stupid questions like, "I don't understand. Where does the tobacco go?" or "This thing is more expensive than a KM and a Mya. How good does it smoke?",etc.

If anyone else was wondering why it's called a hookah syestem, "They are called hookah rigs because multiple hoses run from the compressors." TBO.com

Haha im a qualified diver and ive looked at these things many times.

There are 3 ways to get breathing gasses under the water:

Cylinder (tank) which can come in 10 12 and 15 litre size with 5 and 7 litre "pony" cylinders which are often for backup or they can be used two at a time using an adapted backplate for your BCD as a twinset. They are usually 200 bar or 300 bar which multiplied by the litres tells you how much air is in it.

Rebreathers i call these yellow boxes of death, they contain micro cylinders and many chemicals for scubbing CO2 and as you breath the air is "recycled" these things dont release many bubbles like cylinders do, they can change to the optimum mix for your depth and so on however they have many many many dangers BAD THINGS

The third can be known as a hookah and is a device which often is on a boat or floats and provides air down to the divers (often multiple) these are only used in very shallow depths and often just for people to try diving .

Probably more detail than people wanted but i love my sports

That's so true, supposedly the safe limit is approx. 30ft with a rebreather before it starts to poison you. However the lack of bubbles and the ability to stay underwater much longer than with a cylinder is why Navy seals and special forces use them because they're perfect for killing people. tongue.gif Edited by Tom16689

Almost.

im a uk diver we go much much deeper than in the US erm we can dive here down to 50 meters on our insurance qualifacation depenant.

the depth you can go on a mix varies on the partial pressure you work to, 1.2 1.4 and 1.6 are the most common, 1.2 being uk standard 1.4 commercial diving and 1.6 being military in some countries (some go as high as 1.8 and 2.0) this is all based on oxygen becoming toxic at depth depening on the mix.

working on a PP of 1.4 you take the % mix you are using (21% is standard, higher oxygen % is called nitrox and lower is called trimix or heliox which uses helium) here i assume 21% so take 1.4 and divide it by 0.21 which gives you 6.6 bar which we can convert to be depth in meters at around 56M meaning using a 1.4 PP and a 21% gas mix the maximum depth you can go without risking oxygen toxicity is 56M

now doing the same but with a 36% oxygen mix of trimix we have 1.4 divided by 0.36 which gives us 3.8 bar which we convert to 28M only, so you see the higher % oxygen the shallower you can go.

going deeper means the use of trimix or heliox which i wont go into here. also to take into account is nitrogen narcosis which we call being narced and is the same feeling as being drunk but underwater no long term damage, and decompression stops depending on the mix depth time blah blah blah to allow nitrogen bubbles to leave your blood stream and avoid DCI but that is even more complicated maths which ill only go into on request.

Back to rebreathers, on cylinders you choose your mix or mixes with multiple cylinders however rebreathers adapt the mix to the PERFECT one for whichever depth you are at depending on what PP you set, so you can go just as deep on a rebreather as a cylinder however there is much more to go wrong and your buddy if you have one cannot breath from your equipment in a life or death situation as they can on a cylinder.

Max depth on cylinders i beleive was around 318 meters by nuno gomez and this was using 6 clinders on the back 2 side slung and many on ropes on the way up, along with over 12 hours of decompression stops.

max depth hit on a rebreather i beleive was on a cave dive by a man named dave shaw at 282m who actually died during the dive (google his name its an incredible but sad story and his last moments from his own camera are on youtube for divers education on what went wrong)

so the depths between the two are not very different however clyinders take up more space but they offer backup for your buddy and redundency for you

sorry to thread jack i really love my diving, if you want anymore information on nitrogen narcosis other gas mixtures decompression or decompression sickness and so on please feel free to pm me or start a general discussion topic and link me in pm i would love to answer your questions
