Aqualung Helix Pro Pack Din – 1st, 2nd, Occy, SPG and Bag

Description The Helix Pro features balanced first and second stages, delivering consistent performance throughout the dive. It incorporates Aqualung’s patented Auto Closure Device (ACD) technology, which protects the first stage even when not pressurized. With a sleek, modern design, it offers both durability and long-lasting visual appeal.   Helix Pro Pack Includes: Helix Pro First Stage (DIN) Helix Pro Second Stage Helix Octopus Pressure Gauge Regulator Bag   Helix Pro First Stage Features: Auto Closure Device (ACD): Seals the inlet when not connected to a cylinder valve, protecting internal parts from debris, moisture, and corrosion. Maintains oxygen compatibility, preserves lubrication, and extends service intervals. Permanent Dry Chamber: Prevents moisture entry to keep components clean and dry, enhancing cold-water performance and freeze resistance. Over-Balanced (Auto-Balanced) Mechanism: Automatically adjusts interstage pressure for effortless breathing at all depths and tank pressures, ensuring peak performance throughout the dive. Balanced Diaphragm Design: Delivers consistent, reliable airflow in all diving conditions. Blue High-Pressure Seat: Durable sealing surface that opens and closes with every breath, maintaining optimal performance with all breathing gases and in all environments. Integrated Dust Cap Protection: Shields the inlet fitting and ACD from impact and contamination when off the cylinder, ensuring long-term regulator reliability. HP/MP Ports: Includes 2 HP ports (7/16”) and 4 MP ports (3/8”) perfectly oriented in a “T” shape for streamlined hose positioning.   Helix Pro 2nd Stage Features: Front Cover Opening Channels: Wide radial openings direct water sideways over the diaphragm, preventing freeflow in strong currents and reducing cracking effort by up to 20%. Venturi Adjustment Switch: Ergonomic, overmoulded lever allows precise airflow control, even with gloves. “MIN” setting reduces freeflow risk, while “MAX” setting delivers effortless breathing. Pneumatically Balanced Design: Ensures smooth, consistent airflow for easy breathing at all depths. Heat Exchanger: Prevents ice formation on the valve inlet for reliable cold-water performance. Comfobite Mouthpiece: Patented palate bridge design minimises jaw fatigue and keeps the second stage securely in place. Made from soft, hypoallergenic silicone for comfort. Interchangeable Mouthpiece: Tool-free clamp system allows quick, easy mouthpiece changes and helps reduce plastic waste. Reusable Mouthpiece Clip: Enables fast, repeat mouthpiece replacements without tools. Braided Hose: Offers flexibility, comfort, and easy transport for improved handling underwater and during travel.   Helix Occy Features: Pneumatically Balanced Design: Delivers smooth, consistent airflow for easy breathing in all diving conditions. Integrated Heat Exchanger: Surrounds the valve mechanism to prevent ice build-up by dissipating cold from gas expansion and transferring ambient water warmth. Venturi Adjustment Switch: Easy-to-grip lever helps prevent freeflow at the surface and enhances breathing performance at depth. High-Visibility Hose: Equipped with a 1m yellow hose and bright yellow front cover for quick, easy identification in emergency situations.   Pressure Gauge Features: Easy-to-Read Scale: Clear pressure display up to 360 bar for quick and accurate monitoring. Luminescent Gauge Face: Glows in low-light conditions when shone with a dive torch, for improved visibility during night or deep dives. Shock-Resistant Bourdon Tube: Durable and designed to withstand impacts and harsh diving environments.
