– Air balanced flow-through piston in a chrome plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.

– Patented XTIS (Extended thermal Insulating system) thermally insulates the inner mechanism from the environment, improving cold-water resistance 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.

– External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.

– Air balanced second stage valve smooths out the inhalation effort at varying depths and supply pressures.

– Second stage’s rugged reinforced technopolymer case and front cover with stainless steel frame looks good plus is extremely durable.

– Metal valve housing (barrel) is able to withstand years of aggressive diving.

– User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch.

– Super-flow hose features an oversized bore (larger inside hose diameter) that allows more air to flow on each inhalation.

– Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow.
