LUXURY GOODS - The Regulators
ATOMIC M1 (EXPECTED TO BE AROUND £400)
FIRST IMPRESSIONS: This US company has set out to manufacture its products from materials with "no expense spared". The regulator has a traditional piston-type first stage with a rotating turret and five mp and two hp ports. The second stage is robust-looking, beautifully finished with massive attention to detail. Not at all bulky but with a wide exhaust-T. A very clever internal design does away with the need for a venturi ± switch but it does have a BRA and we thought it had the best mouthpiece of any regulator tested here. We all thought it really cool.

IN THE WATER:
"An excellent breathe and relatively difficult to make free-flow. You could set the BRA and it performed the same at any depth. The exhaust bubbles did not interfere with my vision. The mouthpiece was my favourite. Of all the regulators tested, this is the one I'm going to buy."
"Light in the mouth and absolutely bone dry at all angles. I felt the purge button was a little hard to press but it was otherwise excellent. No problem with exhaust bubbles. A nice regulator. I want one!"
"An excellent breathe. Even beyond 40m it was easy to draw rapid yet deep breaths. Looking up, it was perfectly dry. The purge control was strong enough to empty the second stage but not my mouth and there were no exhaust bubbles in my face. My favourite."
"It felt good to breathe from and the purge was a delight to use. A great design. The controls seemed to make no discernible difference at depth but it refused to free-flow. The mouthpiece was good and solid and the really wide exhaust-T took the bubbles well away from my face. Excellent!"
Inverted: Slightly damp."

INVERTED:Slightly damp.

SECOND-STAGE ASSEMBLY:Assembly: It was easily stripped for cleaning.

ANSTI RESULT:After the initial effort needed to open the valve, very little more was needed during inhalation. Work of breathing = 1.03 joules/litre.
