This is the Aqua Lung Helix Compact Regulator 1st and 2nd Stages
First Stage
- Travel-Ready: the reduced size and weight makes the Helix Compact the ideal choice for travelers
- Yoke or DIN: available in yoke (3,300psi/232 bar max.) or DIN (4,350psi/300 bar max.)
- 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: A braided hose provides flexibility, comfort and excellent transportability
- Standard Aqualung Parts: since it uses standard Aqualung components, your local dive shop can more easily service it
Second Stage
- Pneumatically Balanced: Pneumatically balanced for smooth, easy breathing
- Comfo-Bite: Comfo-Bite mouthpiece is soft yet sturdy and reduces jaw fatigue with its unique palate bridge
- Optimize Your Opening Effort: With the "Mini/Maxi" adjustment knob, you can increase the opening effort, ideal for avoiding freeflow at the surface, or lower the inhalation effort, reducing the work of breathing
