My wife & I have used this product on every dive for 10 years (1800 dives). I've tested it from 40, 60 & 90 feet coming up to 15 feet. From 40 & 60 you could do a 1 minute safety stop. From 90 you don't do any stops but do try to stay within the recommended ascent rate. That will keep you out of the decompression chamber.
Easier than a phony.

I have been diving 47 years and finally got sick of a phony.
Having a safety back-up air supply has many advantages over a standard alternate air source. The most obvious is that it is a separate air supply and allows self rescue in an emergency out of air situation. We are taught to stay with our buddy so that in case of an emergency they are right there ready to help us. Next time you make a dive count the times your buddy is further then arms length from you. You will be surprised that they are much further away more often then you may think. Spare-Air gives you a major advantage over an alternate air source when an emergency arises. Having something to breathe from while you are swimming to your buddy, and then, getting their attention while they have their head in a hole watching a lobster can take several breaths or more of air. Tested and approved, Spare Air is a totally self-contained 3000 psi (200 bars) 3.0 cu. ft. (85 liter), refillable backup air system that's small and easy to use. It was designed to get you to the surface in the event of an emergency; yet, it is small enough to not even know you are wearing it! Spare Air is easy to use and maintain, just put it in your mouth and breathe. Kit includes easy refill adapter so you can fill directly off your own Scuba cylinder. So give yourself that extra edge of safety with Spare Air. The cylinder measures (L x Dia.) 13.4" x 2.25" (34cm x 5.71cm) and weighs 2.17 lbs (985g) Note: All Spare Air cylinders meet certificated specifications of the US Department of Transportation (DOT) with DOT-3AA specification and Transport Canada Safety and Security (TC) with TC-3AAM specifications. Spare Air comes with an owner's manual, holster, safety leash and is covered by a 12 month limited warranty.

How do you carry your 'spare air' tank on your dive? Attached to your BC or your tank?
RICHARD W
I carry it on my BC upside down. It seems to work well that way for me, access wise.
ROBERT B
I attach it to my thigh
BOBBY Y
Zeagle made a holder that attached around the calf of your leg, that had two adjustable buckles. this was about five years ago.
SUSAN H
Attached to my BC. The holster is attached to right side of my jacket at my waist. After I close my jacket it attaches to the other side of my jacket. It is kind of a pain when putting on and taking off my BC but it makes it very accessible under water which is the goal.
brian g
Attached to bc. About 13 in long , on right lower side of bc.
RICHARD G
I LINE DIVE. I USE A DEDICATED BELT FOR SPARE AIR.
JJ DIJKMAN M
I carry it on my BC. this way, i can get to it faster. You don't want to lose time, trying to find it when you need it!
brian g
approx 2.5 inch round by 14 inch with reg installed. When you carry this, take about 2 lbs off weight belt
GLENN W
It is about the size of a bottle of smart water . The large one. It is not very big at all and fits easily any where on you.

I plan on eventually using nitrox. Why would an emergency spare-air also need to be nitrox filled, if you will only be using it for an emergency ascent, presumably? Surely the slight increased N2 for only a minute or two during ascent is not significant? If I buy a regular air device, could I still use it if I switch to nitrox someday?
RENEE M
If you dive Nitrox you will still fill your spare air with regular air. You would never want to switch the spare air to nitrox and then switch the tank back and forth. You just dive Nitrox on your big tank on whatever dive you want/need it and carry your spare air along as always. Do realize that the spare air is a tank. Because of that it has to be checked and certified every so often before some places will allow you to fill it. Also be sure to take it apart and have all the pieces in ziploc bags if you are going to fly with it. It tends to freak out TSA in some places. I always carry the instruction manual which makes some officials more comfortable.
GARY W
David, I am not nitrox certified, so I do not know the answer to your question. I would suggest that you pose this question to Divers Alert Network.
STEPHEN S
I am trying to account for the negative bouyancy for a filled spare air this size to adjust my weights? ( reduce my weight in the pockets) Can anyone provide this information?
MICHAEL H
I have not needed to compensate for the addition of this Spare Air unit to my gear. The Spare Air has been a permanent addition to my equipment for several years now. Any adjustment that you may make will be little if any. Smart purchase. I have been ask why I carry it when there is good visibility and I dive with a buddy. Simple answer if I unexpectedly get deprived of my primary air, I don't want to be forced to hope my Dive Buddy is looking at me when it happens.
ALAN A
Steve, I do not adjust my weights. The negative buoyancy is so minimal it does not seem to affect my weights.
LIN Y
CE approved?
BRYAN H
I don't know what "CE" refers to, but it's pjrimarily an upgrade on the former Spare Air's holster. The air tank is about the same, but painted a pretty yellow color.
GARY W
The packaging that my Spare Air came in bears the CE label. The Spare Air website also list this product as CE approved.
WILLIS R C
Hi Lin, Yes. The Spare Air is CE approved. On the label on my Spare Air, it reads, "CE 0120 WP 207 BAR." When filling your Spare Air from your main scuba tank, be careful to open the valve slowly rather than filling it too fast; it could damage an internal part. Otherwise, it is reliable and a great system.
JAMES M
Yes, CE 0120 WP 207 BAR MAX DEPTH 30 OR 20 METERS DEPENDING ON MODEL
AL B
according to the MFG website they are CE certified
