The Aqualung Helix Pro DIN Diving Regulator is a mid-range, balanced first and second stage regulator that embodies Aqualung's technical excellence. Designed for divers seeking superior performance and durability, it offers a range of features tailored for both recreational and technical diving.
- Balanced First and Second Stages: Ensures consistent and effortless breathing at all depths and tank pressures.
- Auto-Closure Device (ACD): Protects internal components by sealing the first stage when not connected to a cylinder valve, preventing water and contaminants from entering.
- Permanent Dry Chamber: Isolates internal parts from the external environment, keeping them clean and dry, which enhances freeze resistance in cold water.
- Heat Exchangers on Second Stage: Prevents ice formation on the mechanism, ensuring reliable performance in cold conditions.
- Ergonomic Venturi Adjustment Knob: Allows precise control of air flow, even while wearing gloves, to prevent free-flow at the surface and enhance performance at depth.
