Questions and Answers for ScubaPro Octo - Air II Balanced - 5th Generation:

  • Doug:

    Are you still able to inflate your BC with your mouth if you were to run out of air?

    Arthur  (Certified Scuba Instructor at

    Hello, yes it works the same. Hold the dump button and exhale.

  • aldo:

    Hello, Please can you tell me if the ScubaPro Air II balanced scuba octo is compatible with the Mares Dragon Ergo Scuba BC with MRS Plus Weight System. Additionally can I know why this Device is horizontally inverted as compared to other inline units (e.g. XS Scuba Airwave Plus Inline Scuba Octo) The mouth piece on this unit is facing the right side, while the mouthpiece on all other units is facing the left ? Is this a fault with the image or will it be facing the opposite side ? Thank you soooo much for your help and support. Best Regards.

    Mares has a specific attachment for their low pressure inflators. We recommend using the Mares Air Control for an integrated octo. The graphic is confusing, but the Air II uses the same configuration as the others and will work correctly on any BC that it is designed to work with.

  • Tim:

  • Gio:

    is it possible to use this as a primary air source and use the other regulator as a secondary?

    Bob  (Certified Scuba Instructor at

    It is not designed for that purpose.

  • Joshua:

    Can this be placed on a zeagle 911 bcd

    Darrick  (Certified Scuba Instructor at

    Hello Joshua, yes this would fit the Zeagle BCD but if the Zeagle is a newer version you would lose the garden hose connection. If you would want to keep that feature you would need to go with either the Atomic SS1 or the Zeagle Octo-Z

  • Jim:

    is the regulator-side coupling cover for the air2 covers the regulator-side of the coupling when not attached to the hose, preventing debris from entering available separately? i have a late-1990s model air2, but have lost the coupling cover.

    Bob  (Certified Scuba Instructor at

    It''s not an item sold by the manufacturer separately. You might try contacting ScubaPro directly and their technical services department might be able to assist you with one.

This fifth-generation octo/inflator is now easier to use than ever. As a backup regulator in high-stress situations, the AIR2 breathes like a dream, rivaling some second stage models. It is CE-certified for waters 10-degree Celsius or warmer. The large, flexible purge button provides quick clearing when it counts. Divers can also enjoy pin point buoyancy control with the AIR2. Its large inflate and deflate buttons are easy to distinguish, and the device fits comfortably in hand. For reliable performance without dangling hoses, the AIR2 is a standout.

An octo/inflator combines a backup regulator with a BC's buoyancy control system in one compact, at-the-ready unit.  The cool thing about an octo/inflator is that it's always within reach because it's constantly being used to control descents, adjust buyoancy, and vent air during ascents.  In the even of an emergency there's no need to grope for a dangling octo reg; simply pass your primary reg to the diver in need while you take the octo/inflator, enabling you to breath easily and control your buoyancy as you make your way safely back to the surface.

SCUBAPRO introduced the octo/inflator concept to diving almost thirty years ago with the introduction of the original AIR2.  Now in it's 5th generation, it offers even more in both performance and ease of use.

As a backup reg the AIR2 delivers air as smoothly as most primary second stages.  The flexible purge cover is large and easy to locate, allowing for quick clearing when it comes time to take a breath.  In addition, a new dive/pre-dive switch lets you detune the AIR2 when it's not being used, eliminiating free flows.  And unlike traditional dangling octos, the AIR2 is always within easy reach if needed.

As a BC power inflator the AIR2 is very easy to use.  It fits comfortably in the hand, and the large inflate and deflate buttons can be differentiated by both color and touch, improving safety on both ascents and sescents.  The power inflate button features a very light lever so it's easy to initiate inflation.  Also, both inflate and deflate buttons are positioned on top of the housing making them easier to operate when breathing off the unit without having to change hand positions.

If you want a reliable backup reg that's always within easy reach that does double-duty as a BC inflator/deflator, and that streamlines your dive profile by eliminating a dangling octo hose, you're goning to love the AIR2.  It was diving's first octo/inflator and, with five generations of improvements, it's still the best.
