Uniquely shaped fiberglass-reinforced nylon casing carries on the D-Series heritage with the latest advances in breathing performance technology.
Air-balanced Progressive Flow Control Valve is able to deliver abundant airflow with a natural smoothness comparable to breathing on the surface.
Dive/pre-dive system includes a switch on the top of the case with a thumb tab for adjusting the direction of airflow right out of the valve.
Casing design features inner winglets that direct airflow towards the exhaust valve, creating a dramatic improvement in exhalation effort.
Diaphragm is located in the lower section of the casing to take advantage of the pressure gradient in the upright position, making breathing even easier.
Reversible hose attachment allows for either left- or right-side LP hose connections for maximum rigging flexibility.
Large purge button is easy to reach and depress, with or without gloves.
Exhaust tee is compact and efficiently deflects bubbles from the diver’s view while enhancing ease of exhalation.
Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes, from largest to smallest.
Air balanced flow-through piston first stage design delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate.
Patented XTIS (Extended thermal Insulating system) fully insulates the inner mechanism from the environment, improving cold-water resistance by 30% and delaying ice formation in extreme cold-water conditions without compromising breathing performance.
Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
Two opposing high-pressure ports allow the first stage to be positioned either up or down.
Four high-flow and one axial super high-flow low pressure ports on a swivel turret maximize hose routing options.
CE certified according the latest EN250A European Standards for all diving conditions, including extreme cold water.
