Rating: Submersible Systems Spare Air Pack Review - Scuba Gear Customer Reviews
Reviewer: Dale B.
Its very easy to assemble and disassemble. Ive flown to Florida keys as well as Aruba with it now and have had no issues with security. I did buy the travel bag that goes with it and packed it all in my checked gear. Well worth the peace of mind you get by having it on you.

Rating: easy and dependable, and versitile
Reviewer: Thomas B.  -  View all my reviews
Now, please understand that I have yet to use this unit for an underwater emergency, but...I did use it while fogging our horse barn with a commercial fogger. Its well made, solid, easy to use, and I had a great clean air source while enveloped in a cloud of insecticide! Easy to fill, and smooth breathing. I do carry it when using my hookah as well as SCUBA. Would recommend!

Rating: Peace of mind means more dive enjoyment!
Reviewer: James Benners  -  View all my reviews
As new divers, just started studying for open water certification (only did up to first pool dive training thus far), my wife and I decided it would be fun to take our first actual scuba dives with a PADI Discover Scuba excursion in Nassau Bahamas during our last cruise a few weeks ago. Studying my iTouch PADI OWC course, I learned "I am responsible for my own safety" and "there are many dangers in diving but they are manageable risks". Also having twice read the book Diver Down which discusses real life stories of experienced divers who in most cases didnt survive their last dive and how to learn from their divers errors, I decided it would be smart to not rely completely on a buddy breath in an emergency and to have a personal bailout plan as a little added "insurance". Do you remember there are 23 different equipment fail scenarios in which a scuba diver can suddenly have a catastrophic air loss at depth and need backup air to surface? Can you completely trust that your dive buddy will always be close enough to help you in a sudden emergency or may they be distracted enjoying their dive or too far away from you to offer immediate assistance as you struggle to get their attention? Times ticking.... and you cant hold that last breath waiting for your buddy. Can you completely trust your life to rented equipment that you arent 100% certain is maintained properly? I noticed a few different air leaks from the rental equipment (one diver had a tank valve leaking a small stream of bubbles, another had air leaks at a regulator hose connection, and a third diver had some air leaking from a BCD low pressure hose connection). I personally wasnt given enough weights to properly balance my buoyancy (they ran out of weights, it was a very busy dive day). My lower half body kept floating up higher than my upper body. Awkward swimming experience but another lesson to buy my own gear! However, I still felt a peace of mind knowing if my wife or I suddenly lost air at 40 feet, we had a back up to get to the surface that didnt depend on anyone but ourselves - our Spare Air! Even though we witnessed some questionable equipment flaws that needed attention, we still had an awesome and enjoyable experience! We even saw a large Black Tip Reef Shark swimming only 15 away as soon as we arrived at bottom on the reef! What an awesome first dive experience we would have missed out on if we had turned the dive early seeing all those air leaks underwater or if we had not dived at all worrying about our equipment failing! We didnt use our Spare Air on this dive but the peace of mind it gave us strapped to our BCDs in easy reach helped us to have a much more enjoyable experience and I will never scuba dive without it!!! I feel good depending on myself in a personal emergency instead of leaving it up to someone else. Spare Air is the greatest parachute a diver can carry in addition to his dive knife!!! I am not in any way affiliated with a Spare Air company or but Im definitely a customer and promoter of this awesome product!!!

Reviewer: Joseph Dovala
Wanted a small redundant air source for solo drift diving from 60ft depth and up. This 1.7cuft fits the bill perfectly. Small enough to fit in a wetsuit/drysuit pocket. Extremely quick deployment. Tested at 35ft and it gave me 16 full breaths. Gave 4 stars instead of 5 because it should come standard with an actual psi gauge. Otherwise, a very nice peace of safety gear AS LONG AS YOU USE IT WITHIN ITS CAPABILITIES.

Reviewer: XIAOGANG Y.  -  View all my reviews

Rating: Good one "Spare ing" a few points
Reviewer: Radhakrishna J.  -  View all my reviews
Good .... Concept, size, price & color OK .... mounting provisions are a it flimsy. I tried the right shoulder mount but that seems to intefear with my right dump valve & also my reg hose. Will try the back- upside down on tank the next time. Bad ..... the fiilling adaptor platics seem very flimsy & it leaked a lot when filling from my tank .... please keep spare O rings - you will need it. Overall a good value .... gave me aprox 30 breaths at 10 mts.

Reviewer: KHAIRUL FAHMY PAIMIN  -  View all my reviews
Tested at 20m deep and it performed well. Manage to get 16 breath, enough to get to a buddy or surface. This item is psychological - you will feel better knowing its there. once mounted at the bcd, You need to put some Weight on the other side to trim yourself.

Rating: How much does your life cost?
Reviewer: Sergey S.
When i bought Spare Air i was thinking only about safer diving - its true, not only safe but also easy and confident. But moreover if you (like me) live on a high appartment building - its your second chance in case of a fire rescue, especially of you feel a superhero inside, you can try to save not only your life, but the life of your neighbor. So recently i bought two more for my relatives at the 25th floor, just in case, that also made them to try diving (yeeha!).

Rating: Well put together for "basic" shallow water recovery
Reviewer: Terry Harrison  -  View all my reviews
I think the idea is sound and I wanted a small backup for my wife and I during shore diving in Bonaire. If I was more than just a "holiday" diver, I would go the larger pony bottle system.

Rating: Spare Air Pack 3.0
Reviewer: mateusz kwiatkowski
If You value Your life that is a must have. Small enough to make it presence almost unnoticeable but big enough to give you 50 solid breaths. Comes with everything that is needed to use it and refill it. And what i like the most is that you fill it straight from your main tank, and the whole assembly, disassembly and filling take less than a minute (im using high pressure tank).

    can you use spare air for snorkeling. say you wanted to stay down 15 min or so in 10-20 feet

    Darrick  (Certified Scuba Instructor at

    Hello Peter, if you are looking for something that would last that long and with any set-up you go with that will let you breath underwater you would need to be scuba certified to get the unit in questioned fill at any dive shop that fill tanks. But to answer your questions you would need to go with a larger tank if you are looking to breath underwater for more than 3 min.

    Hello, I plan to deliver the spare air (plus the travel pack) to a friend in US and he will bring it up in Greece.

  • Pierre:

    I am a Padi certified diver who is looking for a small system to keep on my boat to do short underwater inspections, cleanings and changes of zincs on prop shafts. Work depth would be between 2 to 10 feet, for about 5 - 10 minutes at a time. But I do not want to bring all my equipment out on the boat each time. Will the spare air system work for this purpose? Note- I will need to have both hands free to do the work, so how do I secure it?

    Bob  (Certified Scuba Instructor at

    That''s not a purpose the Spare Air would be suitable for. For alternate ideas, please contact our instructors at

  • Ken:

    Can the unit be safely refilled from an HP100?

    Bob  (Certified Scuba Instructor at

    It can be safely refilled on any cylinder.

  • Thomas:

    Are the 1.7 CF unit and the 3.0 CF unit the same size? They appear to be separate products. Thanks

    Bob  (Certified Scuba Instructor at

    As each bottle is a different volume they are also different sizes. The 1.7cu ft. tank is smaller.

  • Dennis:

    I am working on getting my Nitrox certification can I use the Nitrox tank with regular air until I get my certification done?

    Darrick  (Certified Scuba Instructor at

    Hello Dennis, you would need to get the Nitrox version of this if you plan to use anything over 21% O2 in this unit.

  • Mark:

    I live on the water. Been a certified diver since 1983. I now freedive spearfish 50-60 but intend to take the PFI course so I can go 100. My wife too. Getting to be little room for error. Can we strap these to our forearm. Wed only use them in an emergency situation. How many breaths at about a 100. (we"d probably only need 1 or 2). Is this an acceptable application?

    Darrick  (Certified Scuba Instructor at

    Hello Mark, you would be looking at around 56 breaths at the surface. Yes this would work for you. Since you are at depth and free diving if you are breathing with this you will have to exhale on the way up. If you breath off of this and hold your breath on the way up you could run into issues.

  • Priscilla:

    This might sound like a stupid question to all you scuba divers... I have never been scuba diving, Im just looking for an air tank to take on a cruise with me (the movie Titanic where the water rushes into the rooms instilled a deep fear of drowning on a boat). My question is: does it actually come with 57 breaths of air already in it? If not, where would a non-scuba diver get it filled? Thank you!

    Bob  (Certified Scuba Instructor at

    It fills off of a divers scuba tank. It comes with it''s own refill adapter. You''d need to have a scuba certification card in order to fill it.

  • Gary:

    Would a spare air system be used as a back-up for an octo, or in place of one?

    Arthur  (Certified Scuba Instructor at

    Hello, a spare air system is to be used for an out of air situation.

  • Joshua:

    I am not a scuba diver, however I have a swimming pool which goes to a depth of 10 feet in the deep end. A couple of years ago I had a hole in the liner which I found eventually by holding my breath, diving and searching but it would have been much easier with an air supply. I dont want to invest in a full scuba setup but would something like this work for this purpose? Also, how do these get re-filled? Thanks.

    Darrick  (Certified Scuba Instructor at

    Hello Joshua, yes this would give you a little of a bottom time to do what you are trying to do. However you need to be a certified diver to use this. We would not ship this to you full. You would need to fill it off a scuba tank or take it to your local dive shop and they can fill it for you but you would need to be a certified diver for that to happen.

  • Jack:

    Hello, is this tank reffillable? And if so, how long would it take to refill?

    Arthur  (Certified Scuba Instructor at

    yes it is. you fill it off of another larger tank and it only takes a minute to fill.

  • yunfeng:

    I saw 1.7cf and 3.0 cf is the same price?

Spare Air

Billed as the smallest, most compact redundant emergency air system available today, the Spare Air has been giving divers that added little bit of comfort and protection for over 30 years!

The Spare Air is a versatile system combining a common demand style regulator with a small aluminum cylinder that allows the divers that extra air needed to handle an unexpected out of air situation during a dive. The small bottle comes in either 1.7 cubic foot or the more popular 3.0 cubic feet and is easily and securely attached to the diver’s equipment with Deluxe Holster and Safety Leash included in the kit. Offering approximately 57 average breaths at the surface, the 3.0 cubic foot version is enough air to safely ascend from 30 meters. Its best use comes from being a small handy unit that is perfect for allowing the diver to solve an out of air or air interrupting situation underwater without having to make an emergency ascent. It can be passed off to a diver in distress to help them get a few breaths of air while they calm down and assess a situation or can allow the owner the air it takes to get to their buddy safely and comfortably for help.

The Spare Air is always ready for use and is easily refilled by using the Yoke Refill Adapter right off the divers own tank! Simply unscrew the protective cap and install the yoke adapter. It’s as easy as that!
