Hi All, I also noticed a few things about Billy B's photo in the sci-amer article. He has all four regs the same style, and the same colour, which is not a problem if you can follow the hose to the cylinder and confirm that you are breathing what you think you are. *BUT* he also has so much, so highly convoluted hose, that I defy anyone to follow a hose back to the cylinder it comes from. Add to that he is wearing gloves, with mitts over the top and there is no way he could confirm that he is on the correct gas. There has been a thread on the pros and cons of yoke v's DIN fittings. Billy gets round this by having what looks like Din regs, with yoke adaptors, neatly combining the worst of both worlds. He also seems to have zero redundency on bottom gas, and both deco gases, not even a (shudder) Y valve, let alone two of everything vital. Perhaps we could all have a good look at the photo, and start a little competition to find all the mistakes? Cheers Jason =:) PS could anyone see a backup timer/depth gauge in the photo?
