Diaphragm first-stage with four mp and two hp ports. Plastic second-stage with heat exchanger and venturi +/- switch.
We liked the design of the environmentally dry-sealed first-stage with a turret that can be used the right way up. We also liked the positive venturi +/- switch design of the second-stage, which was easily felt for but did not protrude. There were excellent hose protectors which did not trap salt water when left to dry. Some liked the way the exhaust tee rested on the chin, although George did not. We liked the blanking ball.
At depth:
George: "Excellent. A very smooth breathe. I would buy this regulator."
Sarah: "I tried all manner of panicky inhalations but it was always excellent."
Steffi: "Probably my favourite."
Steve: "I was conscious of the draw at depth but I liked it a lot. A good positive breathe."
Upside-down: Became dry after two breaths.
In a fast current: Very good.
What the machine found:
With the venturi +/- switch at the minus setting it breathed exceptionally easily at 50m, but in the plus position it gave an unacceptable positive inhalation pressure above 25 lpm.
Work of breathing at 50m: 0.58 joules/litre.
Guide price: £212
