Lightweight and extremely durable, carbon fiber can resist substantial shocks without damage.
Both first and second stages feature a Black Tech scratch-resistant coating on metal parts that protects against the ravages of salt water and corrosion.
A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes, and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flows in cold water or when used as an octopus.
High-flow exhaust valve reduces exhalation for better overall breathing comfort, and the reversible hose attachment allows you to easily adjust hose routing for tech diving configurations.
Patented XTIS (Extended Thermal Insulating system) insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing performance.
Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
Air balanced flow-through piston provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
Patented XTIS (Extended Thermal Insulating system) insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing performance.
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.
