Aqualung Leg3nd Elite Regulator Stage 4 Set

*Stage 4 sets come with 1st stage, 2nd stage octo and pressure gauge*

First Stage

• When the first stage is not connected to a cylinder valve, the Auto Closure Device (ACD) keeps the inlet shut to protect the first stage internal parts from contamination and corrosive water.
  • Preserves the internal lubrication
  • Keeps the inlet filter clean and dry
  • Safer for elevated percentages of oxygen
• Exceptional cold-water performance is achieved by modernising Aqua Lung's three anti-freeze properties:

  Where there's no moisture, there's no ice: The LEG3ND's integrated dry chamber keeps inner components clean and dry by isolating them from the outside environment

  Deep ribs create a large heat exchange surface area that helps to prevent ice forming on the mechanism (+30% vs Glacia / +70% vs Legend 2)

  The new overmolded cap delays ice forming over the external diaphragm

• Auto-Balanced (also known as Over-Balanced)
• Progressive increase of the working pressure to maintain optimum breathing efforts: Depending on the diver's depth, the working pressure of the first stage is automatically elevated to counteract the increased breathing air density
• Ergonomically shaped DIN and YOKE screws made of a bi-material “Soft Grip” surface provide a better hold when installing or removing the first stage – especially with cold hands
• Channeled YOKE screw to prevent water retention.
• Specialised ACD Dust cap attached to the regulator body to protect the inlet fitting and the ACD system from impacts or damage
• Perfectly positioned HP and MP ports provide optimal hose routing

Second Stage and Octo

• New front cover opening channels allow water to flow sideways over the diaphragm
  • Radial openings to prevent freeflows when diving in stronger currents
  • Openings widened to reduce peak inspiratory flow by an impressive 20%
• New overmolded exhaust cover made of elastomer with a “soft touch” effect
• Overmolded air purge
  • Wide surface area makes regulator purging easier
  • Purge depth controller optimizes air flow with minimal effort
• Patented Comfobite mouthpiece reduces jaw fatigue and secures the second stage more comfortably.
• Detachable and reusable mouthpiece clamp allows a quick and simple tool-free mouthpiece change without plastic waste.
• The enlarged heat exchanger helps to prevent freezing of the second stage mechanism
• Air channel deflector
  • Directs the air flow evenly during the inhalation phase
  • Streamlined bi-material deflector lowers the exhalation effort
• Flexible and lightweight Aqua Flex hose with dual protectors

Pressure Gauge

The Aqua Lung Pressure Gauge delivers both remaining air pressure and temperature in one easy-to-read display.

• Easy-to-read scale up to 350 bar rated
• Luminescent gauge face for easy reading in low light
• Integrated temperature scale
• Nitrox compatible up to 50%
• Swiss made, shock resistant Bourdon tube
• One way safety valve
• Hose length is 36”/ 91.44cm
