  • First stage:

    • Auto Closure Device (ACD) - keeps corrosive water out of the first stage inlet by automatically closing as the Core is removed from the cylinder valve
      • This prevents internal lubrication from washing away
      • Safer for elevated percentages of oxygen
    • The balanced diaphragm first stage provides superior, consistent performance
    • The pneumatically-balanced second stage results in smooth, easy breathing
    • Available in yoke (3300 psi / 232 bar max) or din (4350 psi / 300 bar max)
    • The T-shape of the first stage optimizes the location of the 4 MP ports and 2 HP ports
    • Uses parts that are common to other Aqua Lung models for easier servicing

    Second Stage:

    • The easy-to-grip venturi lever prevents unwanted freeflow at the surface while giving a performance boost at depth
    • A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water
    • Equipped with Aqua Lung’s patented Comfo-bite™ mouthpiece along with a reusable mouthpiece clamp
  • First Stage Diaphragm, balanced
    HP Ports 2
    LP Ports 4
    Second Stage Pneumatically balanced
