When comparing performance with price, Core bubbles up to the top. Rated as superior on the Ansti breathing machine and equipped with our unique Comfo-Bite mouthpiece, this feature-rich winner is the best value of any regulator on the market. Comes standard with Aqua Lung's patented auto-closure device (ACD) for sealing water out.

First Stage

• 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
• Venturi Knob Easy control: the in-line ergonomic Venturi knob lets you make precise adjustments, even while wearing gloves
