About Oceanic Alpha 9 CDX-5 DVT Regulator

The Alpha 9 CDX-5 features effortless breathing in a compact design that is extremely tough yet easy to maintain and service, and is paired with a compact over-balanced diaphragm first stage. The CDX5 first stage is made of Chrome Plated Marine Grade Brass and is a Balanced Diaphragm Design. With this design water doesn't enter the first stage, which means the CDX5 is excellent for ice diving (it won't freeze up) or diving in waters filled with contaminants or sediment (it won't corrode). Environmentally sealed, the diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance. As is the Alpha 9 CDX-5, comes ready to use with air or nitrox mixtures up to 40 percent. Two high pressure and four low pressure ports assure a place for all your necessities and accessories.

The Alpha 9 Regulator Second Stage has a Patented Orthodontic Mouthpiece for exceptional comfort and Reduced Jaw Fatigue. The Mouthpiece accommodates the natural Overbite of the human jaw. In Addition the 30" (76.2 cm) Max-Flex Hose with its extreme Flexibility further reduces any Jaw Fatigue, making this one comfortable breathing regulator.

The Alpha 9 is classified as being suitable for use with nitrox breathing gas mixtures containing up to 40% oxygen by volume without the need for special preparation, cleaning or component parts. Regulator weighs 35 oz (992.23 g) and the front profile dimension is only 2.9" (7.4 cm). Regulator comes with a Comprehensive Owner's Manual.

    Comments about Oceanic Alpha 9 CDX-5 DVT Regulator:

    Purchased on a friend's recommendation and couldn't be happier! Only complaint really is the cap to cover around the DVT leaves a black residue the first few times you use it. Make sure to clean thoroughly.

      Comments about Oceanic Alpha 9 CDX-5 DVT Regulator:

      I have about 10 dives on this reg, and Im very happy with it. I like how light weight and low profile the second stage is. It breaths quite comfortably, but Ive only taken it down to 80ft.

      The max flex hose is great. It makes it very easy to turn your head. The reg isnt constantly tugging on your mouth.

      Sometimes, when you turn the tank on, there is a very slow leak directly out of the mouth piece. This can usually be solved by tapping the second stage into the palm of your hand. It seems to have fixed itself as I have used it more. Im not sure if this is specific to my unit, or occurs on all Alpha 9s.

      The 2nd stage also has a bit of a humming sound during exhalation. This could be because I exhale rather slowly. The sound does not occur during a sharp exhale.

      No one else has mentioned that the intake on the 1st stage has the "Oceanic" protective nipple. It stops water from entering the intake of the 1st stage if it is submerged while disconnected from the tank.

      The only thing I would change about the reg is to add a venturi/ crack pressure adjustment knob.
