What’s In the box: 1st stage, 2nd stage, Octo and hoses.
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.
