Aqualung Pack Leg3nd Elite+ Octo + Spg + Bag

First Stage

• AUTO CLOSURE DEVICE (ACD): Keeps the inlet shut to protect internal parts from debris and corrosive water when not connected to a cylinder valve. Helps maintain oxygen compatibility, preserves internal lubrication, and keeps the inlet filter clean and dry, extending service life.

• PERMANENT DRY CHAMBER: Where there’s no moisture, there’s no ice. Isolates internal parts from the external environment, enhancing freeze resistance in cold water.

• DE-ICE: Deep ribs create a large heat-exchange surface to help prevent ice formation. The overmolded cap delays ice buildup on the external diaphragm.

• OVER-BALANCED MECHANISM (Auto-Balanced): Overcompensates interstage pressure to reduce breathing effort, ensuring effortless breathing regardless of depth or tank pressure.

• BALANCED DIAPHRAGM: Provides superior and consistent performance.

• BLUE HIGH PRESSURE SEAT: Core of the first stage. Opens and closes with every breath, forming a perfect seal with durable materials suitable for all conditions and gases. Automatically increases working pressure to counter higher gas density.

• DUST CAP PROTECTION: Protects the inlet fitting and ACD from impacts and damage, sealing the first stage when off the tank.

• DIN AND YOKE SCREWS: Ergonomic bi-material screws with Soft Grip surface for improved handling, even with cold hands.

• CHANNELED YOKE SCREW: Prevents water retention.

• HP / MP PORTS: Perfectly positioned for optimal hose routing.

• AVAILABILITY: DIN (4,350 psi / 300 bar max.) and YOKE (3,300 psi / 232 bar max.).

Second Stage

• COVER OPENING CHANNELS: Allow water to flow sideways over the diaphragm, preventing freeflows in strong currents and reducing cracking effort by 20%.

• AIR CHANNEL DEFLECTOR: Streamlined bi-material component evenly directs airflow and lowers exhalation effort.

• VENTURI ADJUSTMENT SWITCH: Precise airflow control. “MIN” reduces valve assistance to avoid freeflow; “MAX” maximizes assistance for lower inhalation effort. Easy to operate even with gloves.

• CRACKING EFFORT ADJUSTMENT: Allows fine-tuning of breathing performance according to diving conditions.

• PNEUMATICALLY BALANCED: Smooth, easy breathing at all depths.

• HEAT EXCHANGER: Prevents ice formation at the valve inlet.

• OVERMOLDED AIR PURGE: Large, easy-to-control purge area for effortless clearing.

• OVERMOLDED EXHAUST COVER: Soft-touch elastomer cover provides added protection.

• BLACK COATING: Stainless-steel components feature a black Titadur® multi-layer coating for superior durability. Polymer parts are overmolded in black and anthracite tones for an exclusive finish.

• COMFOBITE MOUTHPIECE: Patented mouthpiece with palate bridge reduces jaw fatigue and keeps the second stage securely in place. Hypoallergenic silicone.

• INTERCHANGEABLE MOUTHPIECE: Detachable, reusable clamp allows quick, tool-free replacement, reducing plastic waste.

• REUSABLE MOUTHPIECE CLIP: Enables fast and easy mouthpiece changes.

• AQUA FLEX HOSE: Lightweight, flexible hose with dual protectors.
