Aqualung Regulator Helix Pro

First Stage
• Balanced Diaphragm – Provides superior and consistent performance.
• Blue High Pressure Seat – The core of the first stage. The Blue High Pressure Seat opens and closes with every breath, forming a perfect seal with durable materials that work in all conditions and with all gases. The working pressure of the first stage is automatically elevated to counteract increased breathing air density.
• Dust Cap Preotection – Attached to the regulator body, the Dust Cap protects the inlet fitting and the Auto Closure Device from impacts and damage. It also seals the first stage when it’s off the tank.
• High Pressure/Medium PRessure Ports  – HP and MP ports in a “T” shape: 2 HP ports (7/16”) and 4 MP ports (3/8”), perfectly oriented for streamlined hose positioning.
• Availability – DIN (4,350 psi / 300 bar max.) and YOKE (3,300 psi / 232 bar max.).

Second Stage
• Cover Opening Channels – Front cover opening channels allow water to flow sideways over the diaphragm. Wide radial openings prevent freeflows in strong currents and reduce cracking effort by 20%.
• Venturi Adjustment Switch – Allows precise airflow control. In “MIN”, valve assistance is reduced to avoid freeflow; in “MAX”, assistance is maximized for lower inhalation effort. Overmolded elastomer and ergonomic lever allow adjustment even with gloves.
• Comfobite – Patented, comfortable mouthpiece with a unique palate bridge that reduces jaw fatigue and securely holds the second stage in place. Made from hypoallergenic silicone, soft yet durable.
• Interchangeavle Mouthpiece – Detachable and reusable mouthpiece clamp enables quick, tool-free changes, reducing plastic waste.
• Reusable Mouthpiece Clip – Enables fast and easy mouthpiece replacement using a removable, reusable clip.
• Braided Hose – Provides flexibility, comfort, and excellent portability.
