First Stage

  • Cold Water Resistant Cold water resistant in waters below 50-degrees Fahrenheit or 10-degrees Celcius
  • Auto-Closure Device Prevents corrosive water out of the first-stage inlet by automatically closing as the core is removed from the cylinder valve. This prevents internal lubrication from washing away and is safer for higher proportions of oxygen
  • Balanced Diaphragm A balanced diaphragm provides superior, consistent performance
  • Yoke or DIN Available in yoke (3,300psi/232 bar max.) or DIN (4,350psi/300 bar max.)
  • HP/MP Ports and “T” Shape 2 HP ports (7/16”) and 4 MP ports (3/8”), perfectly oriented in a “T” shape for streamlined hose positioning, reduced exhalation effort, and sending bubbles out of your field of view
  • Up to EAN 40 Compatible with up to EAN 40 right out of the box

Second Stage

  • Comfo-Bite Comfo-Bite mouthpiece is soft yet sturdy and reduces jaw fatigue with its unique palate bridge
  • Pneumatically Balanced Pneumatically balanced for smooth, easy breathing
