By Aqualung | In Stock at IDC Vancouver | Available in Yoke or DIN

Experience smooth, effortless breathing on every dive with the Aqualung Helix Pro Balanced Diaphragm Regulator. Widely recognized as one of the most popular regulators for travel, the Helix Pro packs professional-grade performance into a lightweight, mid-range design that excels in both tropical waters and cold Pacific Northwest conditions.

Equipped with a balanced diaphragm first stage and pneumatically balanced second stage, the Helix Pro delivers consistent air delivery regardless of depth or cylinder pressure. Its environmentally dry-sealed chamber protects internal components against ice formation, salt spray, and waterborne contaminants, while Aqualung’s patented Auto-Closure Device (ACD) seals the inlet the moment it is removed from the tank valve.

Key Performance Features

• Balanced Diaphragm First Stage: Delivers superior, smooth breathing performance that remains unchanged as depth and cylinder pressure decrease.
• Auto-Closure Device (ACD): Automatically closes over the inlet to keep water, silt, and corrosive salt out of the first stage body.
• Environmentally Dry-Sealed: Dry chamber prevents internal freezing in cold water while protecting internal parts from ambient water contamination.
• Pneumatically Balanced Second Stage: Reduces inhalation resistance for effortless gas flow throughout your dive profile.
• In-Line Venturi Switch: Ergonomic lever allows easy adjustment to prevent free-flow on the surface or at entry points.
• Parts for Life Eligible: Qualifies for Aqualung’s famous Parts for Life program when maintained according to factory service schedules.
• Travel-Friendly Profile: Compact and lightweight body makes it an effortless addition to dive luggage.
