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 smoothes 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.
