trux all the topics about spare air were about if it is a good or bad thing well, i don\t need advice on that, cause i am positive that i want myself one going to use it in pool for fun. I was asking which of them are quality products and whitch not i was considering to order the one form ebay , added link on my first post in this topic

Just make sure that you always breathe or you blow bubbles if you doing any kind of apnea after taking a breath at depth. This is a basic skill you learn when you are taking any scuba classes to help you avoid lung overexpansion injuries.

I don't know if you are familiar with this issue so if you need more insight on it let me know.

Are you aware that the bottle does not hold more air than for just a very few deep breaths? Depending on the model, the bottle contains 30-100 liters of air (and not all of it is usable). That may be good for some 5 - 20 deep breaths, so if you plan it for using it during an hour of a training session for your breath-up, you'd rather need a standard 10 liter (or bigger) bottle. Besides it breathing through a regulator demands always little bit more effort than breathing directly plain air, so personally I would not really try doing it when training in a pool. Well, that told, I am curious about your experience, so once you try it let us know.

The most known are probably bottles from Spare-Air

If you took a look at that link i gave than you saw that this one contains double amount of air compareing to the older versions of spare air tanks. it is 6 cubic feet of air .

Also they say you can fill it with nitrox...





I will let you know when i have tried it out

Ok, I just have to ask, "What the hell are you trying to do?"

I have a spare air and use it when freediving with my scooter, in case it floods when I'm down 100' and I only need a single breath to make it back to the surface.

For scuba diving it's worthless below about 30'. I know underwater photographers who use them down in the islands to solo dive, and shoot pictures, in 30' of water. They aren't that deep, and no where near a deco situation, so the small amount of air it provides is enough to keep the DM's off their backs.

For anything deeper, or longer, you need to sling a bottle- 40cft. works out pretty nicely. Some divers strap them to their main tanks and call them "pony bottles" but I would rather sling mine, like a stage bottle, so that it's more useful and can be removed and given to a buddy if needed.

The nitrox part is a joke, and proves that you haven't taken a nitrox class yet because you would know this if you had. You can throw up to 40% nitrox into any tank- as long as your not mixing that gas, through P.P. blending, IN the tank. Many places who pump nitrox, including any boat/shop that I have worked at, will use a "stick" for their large scale "recreational" mixes and go to P.P. for technical mixes and trimix fills. With the "stick" you can use any tank- as long as you don't go above 40%. You don't need to spend extra for a bottle that has this sticker on it.

It sounds like you need a pool with a better air filter, not a mini tank of gas. You also wouldn't want to be doing your breath-up on nitrox for dynamic training to begin with- and there are many threads on here that go into that in much greater detail.

So, please tell us what you REALLY want to use this thing for and what kind of problems your having that makes you think this will help.

a waste of money, why not buy a 13 or 19 cu. pony bottle for 119.00 and a cheap reg.under a $100.00. Lisa from 123scuba.com has a nice reg. for 60.00 first stage and 60.00 for a 2nd stage new. Every time I see a spare air I have to laugh at the sucker for buying one. How deep and how far are you going to go with that. And you are going to ease your mind that if you have trouble it might save your life, no way it may leak 2 to 4 cu. during the dive. And resale , you will never get a quarter of your money back, always can sell a pony and a reg.

Hey man what is wong with you?? i am well awere that nitrox tanks are different only because usually nitrox is written on it and you can fill any tank with nitrox if you want. Just when they sold it they stated that maybe you would like to fill it with nitrox instead.


I am actaully very sorry for making this thread, not a singe answer to my original question only stuff like , hey dude wtf is wonrg with you, this is pointless and you have taken any classes at all......

Maybe it is usless..... but i will definately try it our myself.* ]


Also thanks for information, pany bottle might be another solution.

[JCDenton]

Also i am not harsh at all just. Here are some smileys to prove that

[trux]

There was no bad intent on our side, we were just trying to spare you of spending unnecessary $300 (+the daily filling fees) + the discomfort of swimming with the tank (whatever small it is) and possible risks of "unnatural" breathing when freediving. For that price you can possibly find a more expensive pool with better quality of air, or drive a few miles farther.

Also, when training with the tank, be sure to have a good buddy permanently surveying you, and knowing how to handle LMC, blackouts and barotrauma. The buddy should be always watching you even when not diving with pressurized air, but in such case the risk of LMC and blackout is simply higher due to more variables and less control in breathing up.

Also, it is a wise precaution to check out where the closest deco-chamber is - although as a scuba diver, you are well aware of the risks of breathing pressurized air, an accident can still happen easily when it is combined with breath-holding - a small distraction, stress, loss of focus, reduced judgment due to hypoxia can easily cause that you forget exhaling or cannot open the epiglottis due to a light samba when surfacing. Getting to the specialist fast may be crucial in such case, so be sure to instruct your buddy how to drive there.

Personally I think that combining tanks and freediving is not wise, is impractical, uncomfortable, dangerous, erasing the "free" from freediving, and simply makes no sense, but if you are decided to buy the tank anyway, let us know about your experience, and whether it is usable at all.

[Jon]

I'm still trying to figure out what your original question was????

In case you missed it in my post I actually OWN one and it does have some, very, specific uses- like as a bailout when freediving with a scooter on shipwrecks.

For just about anything else it's worthless, as stated by many others on here.

As far as durability goes, if that was your only question, mine has lasted just fine over the past 8 years that I've owned it. It's not as rugged as a standard reg and pony/stage bottle set up, but's rugged enough.
