The Oceanic Alpha 9 CDX5 regulator was initially designed as an simple and economical regulator but it quickly became apparent that this combination of an environmentally sealed, over-balanced first stage and a standard downstream second stage was capable of great things. The CDX5 first stage delivers excellent cold water reliability and high performance whilst the Alpha 9 second stage delivers reliability and low maintenance costs through simplicity.

The CDX5 first stage uses an over-balanced diaphragm design to provide responsive high flow rates with performance that progressively improves as depth and gas density increase to deliver the same performance levels regardless of the depth or cylinder pressure. The Alpha 9 CDX5 also benefits from an environmental seal to give it extra cold water protection and reliability by prevent direct contact between the internal components and the surrounding water which, in extreme cold conditions, could lead to ice crystals forming. The barrel shape first stage has four low pressure and two high pressure ports distributed equally on either side of the body for convenient hose routing.

The Alpha 9 second stage uses a simple downstream valve for maximum reliability and the most cost effective approach to diving. The stripped down valve and minimalist design makes the Alpha 9 very light and comfortable to use. The front cover retaining ring and mouthpiece can be changed to customise the look of the second stage. The large soft front cover allows easy purging to clear water from the housing in an emergency. A wide exhaust covers helps to push exhaled gas away from the front of the face and up the side of the head.

On top of all these great features all UK purchases of the Oceanic Alpha 9 CDX5 regulator are protected by a Lifetime warranty once registered. To maintain the warranty the regulator must be serviced annually within a month of the purchase anniversary at an authorised Oceanic Dealer. To make the deal even sweeter Oceanic will even provide the service kit free of charge to the service centre, making it even cheaper to own and maintain your Oceanic regulators.
