• Exhaust tee increases performance while directing bubbles out of the field of view
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
• Air-balanced first stage diaphragm delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate

Second Stage

• Air-balanced valve smoothes out the inhalation effort at varying depths and supply pressures.
• Rugged reinforced technopolymer case and front cover are able to withstand years of aggressive diving.
• Titanium barrel is rugged, anti-corrosion and lightweight for long-term reliability.
