First stage

• TRAVEL-READY The reduced size and weight makes the Helix Compact Pro the ideal choice for travelers.
• AUTO CLOSURE DEVICE The ACD keeps the inlet shut to protect internal parts from debris and corrosive water when not connected to a cylinder valve. It helps to maintain oxygen compatibility, preserve internal lubrication, and keep the inlet filter clean and dry. This extends the life of the first stage between services.
• PERMANENT DRY CHAMBER Where there's no moisture, there's no ice. The Permanent Dry Chamber keeps internal parts clean and dry by isolating them from the outside environment. This enhances overall freeze resistance of the regulator when diving in cold water.
• OVER-BALANCED MECHANISM Also known as Auto-Balanced, the Over-Balanced Mechanism overcompensates the interstage pressure to reduce your breathing effort. Regardless of depth or tank pressure, it provides effortless breathing from the beginning to the end of your dive. This results in superior performance at depth.
• BALANCED DIAPHRAGM Provides superior and consistent performance.
• BLUE HIGH PRESSURE SEAT It is 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 gasses. The working pressure of the first stage is automatically elevated to counteract the increased breathing air density.
• DUST CAP PROTECTION 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 and "T" Shape o 2 HP ports (7/16”) and 4 MP ports (3/8”) perfectly oriented in a “T” shape for streamlined hose positioning.
• AVAILABILITY DIN (4,350psi/300 bar max.) and YOKE (3,300psi/232 bar max.).

Second stage

• COVER OPENING CHANNELS The Front Cover Opening Channels allow water to flow sideways over the diaphragm. The wide radial openings prevent freeflows when diving in strong currents and reduces cracking effort by 20%.
• VENTURI ADJUSTMENT SWITCH The Venturi Adjustment Switch allows divers to precisely control and adjust the air flow. In the “MIN” position, the valve's assistance is minimized, resulting in a higher inhalation effort, ideal to avoid freeflow. In the “MAX” position, the valve's assistance is maximized, resulting in a lower inhalation effort. The overmolded elastomer and ergonomically designed lever allow control of the air flow even while wearing gloves.
• CRACKING EFFORT ADJUSTMENT Cracking effort adjustment system allows the diver to fine tune the breathing performance of the regulator depending on the different diving conditions.
• PNEUMATICALLY BALANCED For smooth and easy breathing at all depths.
• HEAT EXCHANGER Prevents ice forming on the valve inlet.
• COMPACT DESIGN Ideal for smaller faces, such as those of women and younger divers, ensuring it doesn't obstruct their field of vision underwater. Lightweight, it also reduces fatigue when held in the mouth during long dives.
• COMFOBITE MOUTHPIECE A patented and comfortable mouthpiece featuring a unique palate bridge reduces jaw fatigue and securely holds the second stage in place. Made from hypoallergenic silicone, the orthodontic mouthpiece is both soft and sturdy.
• INTERCHANGEABLE MOUTH PIECE The detachable and reusable mouthpiece clamp allows for quick and simple tool-free change, avoiding plastic waste.
• REUSABLE MOUTHPIECE CLIP Perform quick and easy mouthpiece changes using the removable, reusable clip.
• BRAIDED HOSE Provides flexibility, comfort and excellent transportability.
