These are not new. They were in use at least 20+ years ago for military helicopter crew over water. Designed to give enough air to get out of helo after a water crash as the helo is top heavy and will roll inverted shortly after submerging. Your not supposed to egress from fuselage until after the inversion to ensure there are no rotorblades to cut you short. They mounted directly on the chest of the crewmans flight rig. If you need one of these for coming from a deep dive, your gonna need hyperbaric treatment because they will not allow time for safety stops. They have to be hydro'd like any other high pressure tank and can be refilled if you have the correct adapters.

This is not a great safety system. A 6cf pony bottle with O2 or Nitrox would be a much safer bailout. While 3 minutes of air is enough to reach the surface from quite deep (over 130 feet) that's not considering the increased density of the air at depth. What lasts 3 minutes at 30 feet will only last 2 at 60 feet, and so on. Also the fact that there is no way of securing the system while you are using it is troubling. If the piece got knocked out of your mouth, it's likely to float away before you have time to recover it where as a proper tank with regulator hose can be recovered. Also you won't be loosing $500 if it does fall out.

Just extend your traditional snorkel by one metre. you will find that you cannot breath at all if you descend to say 1. 2 metres. this is why this is so dangerous. this kit is using pressure feed air at depth. and that air will expand again in your lungs as you ascend. can be potentially fatal if you dont know what you are doing ( divers are trained in this knowledge. with standard old fashioned mask and standard length snorkel / fins its easy to descend to six metres with a good technique on one lung full of air taken at sea level and have some fun. and its cheaper: )

Not as good air tank as I only made 4: 30 minutes with repetitive attempt.
At more depth like 1 atm the air time will be only half of the above mentioned.
Fun is over soon with this gadget so I can say it is a waste of money.
And with improper trained person the are many dangerous threat of injury from open water diving.
Get trained and licenses you will know why you will not enhanced by this product.

Spare Air's are absolute garbage. This isn't even enough air to get to the surface from 60 feet. Your best bet is to stay near your buddy and use him as a backup supply. If you can't do that. use doubles with an isolator manifold and learn how to do a valve drill. If you must have some type of pony bottle. make damn sure it isn't smaller than 19cf. 19cf is barely enough to get most people to the surface from 130 feet.

WAIT! So you're filling from your scuba tank. That means what ever air that is in the Spare Air is subtracted from from you main tank, the increased total volume of air is ZERO, nada, zilch. Why not just buy a cheaper pony tank and cheap regulator, which will do the same thing, but not subtract from the main tank. This product strikes me as a solution looking for a problem.

Great, with this you can run out of air twice on the same dive. No serious scuba diver would have one of these as backup. I personally carry a 30 cf pony tank and with it I'm sure I'll reach the surface safely from recreational limits. The spare air would only be good for those diving shallow reefs but if you are diving that shallow you could cesa safely anyway.

Its worth the buy. It can save your life, plus you can go shallow water diving without the need for a harness and regulator. The Spare Air is only useful for fairly small depths. Lets say you are at 20 meters, then you will have plenty of time to fix whatever mechanical issue you have. Or to go to the surface. Pretty neat if I say so myself

I was looking into this not as a toy but to use for some shallow water scuba diving. What I mean is like exploring reefs in very shallow water where you would normally just use a normal diving mask just to get more time under the water. Now for that, would you recommend a product like this?

Hello dear
Could you tell me what is your country?
Could you tell me how long it can stay under water? And how deep?
Could you tell me how much is this product in your country?
Could you tell me how much if you send it to me here in Egypt - Cairo
Thanks for your help.

I've been looking for a device to help me explore the lake I live near I can't afford a scuba bottle and scuba equipment but I want to stay under the water for extended periods of time how much is a rebreather and is there any other way to do this in a relatively cheap manner

Mr.
I was just on e bay & to let everyone know I saw three prices that wont break the bank for the spare air & they are 83 dollars, 89, dollars & 90 dollars but those are the only three the rest are 200 to 400 dollars just wanted to help out everyone no matter ur skill level underwater.

I have that same tank and I can stay underwater for 25 minutes 1m with 3k psi its made to be able to ascend from 100 ft relatively safely. Although I would never attempt it for fear of decompression, but it will get you to your partner at any depth in an emergency no problem.

My dad just gave me one, this will be so useful in case of any emergency. i deal with beginners who do introductory many times. If anything happens this will be a great tool. imagine if a customer drowns or dies that would be devastating to the company. always be prepared.
