Diaphragm first-stage with five mp and two hp ports. Plastic second-stage with venturi +/- and dive/pre-dive switch. Cold-water spec.
The tall turret of the Mk14 first-stage usually needs to be used inverted, and some hoses do not get ideal routeing, but there is an additional mp poron the top. The venturi +/- switch of the second-stage was thought too hard to get at, especially with gloves, and the dive/pre-dive switch seems to be a BRA with just two settings - high and low.
At depth:
George: "A very good breathe. The dive/pre-di control certainly worked. It seems to be a snag-free design but very big in the mouth, though comfortable."
Sarah: "I thought this to be only an average breather but the controls were simple and effective. It has one of those big second-stages that I was constantly visually aware of."
Steffi: "The air flow was fine but there seemed to be some resistance. Head tilted back it worked real fine but I would not use it in a cave. There seemed to be too many knobs to make it go."
Steve: "I could feel a slight resistance at the end of each breath but, knobs apart, I liked it."
Upside-down: Kept a fine spray of water.
In a fast current: Very good
What the machine found:
One of the best performers, albeit with some extra effort needed to crack open the valve and initiate the air supply.
Work of breathing at 50m: 1.28 joules/litre.
Guide price: £219
