Aqualung Octopus Helix Compact Pro

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 the “MIN” position, valve assistance is minimized to avoid freeflow; in the “MAX” position, assistance is maximized for lower inhalation effort. The ergonomic overmolded elastomer lever allows easy operation even while wearing gloves.

• PNEUMATICALLY BALANCED – Ensures smooth and effortless breathing at all depths.

• HEAT EXCHANGER – Prevents ice formation at the valve inlet.

• COMFOBITE MOUTHPIECE – Patented, comfortable mouthpiece with a unique palate bridge that reduces jaw fatigue and securely holds the second stage in place. Made from hypoallergenic silicone.

• INTERCHANGEABLE MOUTHPIECE – Detachable and reusable mouthpiece clamp allows quick, tool-free replacement, reducing plastic waste.

• REUSABLE MOUTHPIECE CLIP – Enables fast and easy mouthpiece changes using a removable, reusable clip.

• BRAIDED HOSE – Provides flexibility, comfort, and excellent transportability.

• HOSE AND FRONT COVER – Includes a 1 m yellow hose and yellow front cover for easy identification in emergency situations.
