• Beuchat antifreeze system on the first stage and heat transfer system on the second stage • Over-balancing • Reduced weight and bulk for both the first and second stages. • Bubble deflection system.

First stage
• Over-balanced diaphragm first stage to ensure safety if ever solicited by diver assistance + D.S. inflation + dry suit inflation + delayed surface marker buoy inflation, … (at 70 bar the MP increases by about 10 bar which increases air flow to the second stage despite the HP decrease)
• Airflow performance
• Optimisation of weight and bulk
• First stage equipped with the antifreeze system (Beuchat patent)
• 4 Medium pressure ports
• 2 High pressure ports
• Axial ergonomy of the HP and MP ports
• Simple to upkeep and maintenance
• 230 bar A-Clamp and 230/300 bar DIN connectors

Second stage
• New compact and light second stage
• Air flow performance, comfort, and easy breathing
• Optimised new design for the bubble deflection system which directs bubbles away from the field of vision
• Balancing to optimise performance in all conditions
• New expansion chamber design improving the stability of the Venturi system
• New antiallergenic silicone mouthpiece allows for a better position in the mouth
• Venturi system adjustable by lateral valve
• Adjust sensitivity with an adjustment knob
• Simple to upkeep and maintenance
• Large exhaust valve limiting expiatory vibrations
