1^st stage

UNFREEZABLE END CAP TECHNOLOGY
1st stage end cap prevents ice build up in extreme cold water to prevent the 1st stage freezing.

OVER BALANCED
Over compensating 1st stage allows for maximum performance at depth.

PVD COATING
PVD coating increases durability, reduces wear and tear for longer-lasting premium appearance.

ERGONOMICALLY DESIGNED
Seven optimised port positions (5 x MP 2 x HP) for increased diver comfort and reduced snag hazards.

AUTO CLOSURE DEVICE
ACD prevents water and debris from reaching 1st stage parts or lubrication, extending life between services.

2^nd stage

COMFOBITE
Patented Comfobite mouthpiece reduces jaw fatigue. Secures the 2^nd stage more comfortably.

LAMINAR FLOW VALVE
Smoother breathe and reduced vibration.

DOUBLE SWIVEL HOSE
Reduces tension on both ends of the hose to improve comfort.

PROGRESSIVE PURGE
Delivers precise airflow control for purging or deploying an SMB.

REVERSIBLE SPINDLE
Hose can be switched from one side of the 2nd stage to the other to suit configuration.

FEATURES

First Stage

• PVD coated brass body with heat exchanging ribs for maximum thermal performance.
• Ribbed diaphragm clamp for improved heat exchange in cold water conditions.
• Unique over-balanced diaphragm design – as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a faster rate than ambient. This results in superior performance at depth.
• ACD system prevents water ingress.
• 5 x medium pressure ports for improved hose orientation, 2 x angled high pressure ports for optimal hose routing and fitting of transmitters.
• Double swivel hose for greater freedom of movement and comfort.

Second Stage

• Ergonomic and simple to use venturi lever.
• Large breathing effort adjuster makes adjustment easy in cold water whilst wearing gloves.
• Laminar flow valve.
• 2 stage progressive purge button.
• Reversible second stage for either a left or right hand gas supply configuration.
• A heat exchanger dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water for a more comfortable breathe.
• Features an innovative Diver Changeable Exhaust system (DCE). The system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. The regulator is supplied with both sets of exhaust tees.
• Comfo-bite mouthpiece
• Flexible nylon braided hose, which has better cold water performance than traditional rubber hose.
• Designed and manufactured in the UK.
