Product Information
The Aqua Lung Helix Compact Pro reduces the size and weight of the Helix Pro first stage while keeping the balanced diaphragm design and sealed internals. The smaller body cuts packed weight for travel and sits closer to the cylinder valve.
The second stage is pneumatically balanced with heat exchangers to resist icing in cold water, a venturi control for surface free-flow management, and a Comfo-Bite mouthpiece. Yoke and DIN configurations are available.
- Travel-Ready: The reduced size and weight make the Helix Compact ideal for travelers.
- Auto-Closure Device: Prevents corrosive water from entering the first-stage inlet by automatically closing when the core is removed from the cylinder valve.
- Permanent Dry Chamber: Protects internal parts from water or contaminant damage, ensuring extreme durability.
- Yoke or DIN: Available in yoke (3,300 psi/232 bar max.) or DIN (4,350 psi/300 bar max.) configurations.
- HP/MP Ports and "T" Shape: 2 HP ports (7/16”) and 4 MP ports (3/8”), perfectly oriented in a “T” shape for streamlined hose positioning, reduced exhalation effort, and sending bubbles out of your field of view.
- Braided Hose: Provides flexibility, comfort, and excellent transportability.
- Standard Aqualung Parts: Uses standard Aqualung components, making servicing easier at your local dive shop.
- Pneumatically Balanced: Ensures smooth, easy breathing.
- Optimize Your Opening Effort: “Mini/Maxi” adjustment knob allows you to increase the opening effort to avoid freeflow at the surface or lower the inhalation effort, reducing the work of breathing.
- Cover Opening Channels: Wider opening allows water to pass sideways over the diaphragm, preventing freeflow in strong currents and reducing cracking effort.
- Prevent Free Flowing: In-line ergonomic Venturi knob allows precise adjustments, even while wearing gloves.
- Comfo-Bite: Soft yet sturdy mouthpiece reduces jaw fatigue with its unique palate bridge.

Frequently Asked Questions
How often does a scuba regulator need servicing?
Follow the interval in your regulator's manual, since manufacturers commonly specify an annual inspection or a set number of dives and many warranties depend on it. A regulator is life-support equipment, so service belongs with a factory-trained technician rather than being attempted at home. Have it looked at sooner than scheduled if you notice increased breathing effort, free-flow, bubbles, or water in the second stage.
How do I rinse and care for a regulator after diving?
Make sure the dust cap is dry and firmly seated over the first-stage inlet before the regulator goes anywhere near water, because water inside the first stage is the leading cause of internal corrosion. Rinse in fresh water without pressing the purge button, since purging while depressurized can draw water back into the second stage. Shake out the water and hang it to dry with the hoses in wide, gentle loops rather than tight bends.
Can I fly with a scuba regulator?
Regulators travel well and are usually best carried in hand luggage where they will not be crushed or lost. A regulator holds no gas of its own, so there is nothing inherently problematic about it on an aircraft, though the airline and security screeners always have the final say. Pack it dry with the dust cap in place, in a padded regulator bag or wrapped in soft gear.
Can I use my regulator with nitrox?
Many modern regulators are supplied as suitable for nitrox mixes up to 40 percent oxygen, which is the widely used recreational industry standard, while anything above that requires dedicated oxygen-clean equipment and procedures. Confirm what your specific regulator's manual states, and follow your nitrox training and your fill station's requirements. Never assume a regulator is oxygen-service clean simply because it looks clean or is new.
What is the difference between DIN and yoke regulators?
A yoke (A-clamp) fitting clamps over the tank valve and is the most common connection across much of the recreational world, while a DIN fitting screws into the valve and is standard in much of Europe and in technical diving. DIN captures the o-ring inside the threads, which many divers consider more secure, but yoke is often what rental cylinders provide. Adapters exist in both directions, so check what is used where you dive before deciding.
What is the octopus regulator for?
The octopus is your backup second stage, carried so you can share air with a buddy who is out of gas, or breathe from it yourself if your primary fails or free-flows. It is normally on a longer, brightly colored hose so it is easy to find and hand over under stress. Secure it in the triangle between your chin and the bottom of your rib cage so it is instantly accessible and not dragging through sand or coral.
How should I store a regulator between dive trips?
Store it fully dry, out of sunlight, with the dust cap in place and the hoses in wide loops rather than tightly coiled. Avoid hanging it by the second stages for long periods, which stresses the hose fittings; laying it flat in a padded bag or hanging it by the first stage is kinder. If it has sat unused for a long stretch, have it checked before your next trip rather than assuming it is ready to dive.
