Well, look at it this way: a poodle jacket is either a color-coded bag you put a reg into, denoting the supposed contents of the tank it's hooked up to, or it is a stretchy color-coded sleeve you put over a tank, again denoting the alleged contents of the tank. If you've never heard of it, consider yourself lucky. The problem with these devices is that they rely on you NEVER making the human error of putting the wrong reg in the wrong pocket or wrong sleeve on the wrong tank. Being human, you or your friend eventually will make that mistake, and possibly breathe the wrong mix at depth, which is quite likely to be fatal. WKPP has written extensively about dedicated tanks permanently marked for gas MOD, and the importance of that marking being the only clue as to which reg and tank to select from. Colored regs, different regs, always hanging the O2 on one side , the nitrox on the other still feed you into the same human error trap, as above The correct method (read: you cannot make a mistake) is to dedicate and mark the bottles permanently, hang them wherever, with whatever reg, turned off. Then when you need your, say, 70 fsw deco gas, you look around, find the bottle marked 70, take the reg from what you think is that bottle, put it in your mouth, find the 70 bottle again and turn it on. Then if you can breath, you know you've got the right gas going. Mistake-proof. It's not rocket science folks, and forgive me if I've left out any fine details, but that's the basics of it. The core misunderstanding in other bottle marking schemes (or gas mixing blocks for that matter) is the inadequate evaluation of the risk versus consequences curve. If I put the wrong color reg on the wrong bottle or throw the mixing block swith to any of the multiple wrong positions, I die! Hence the KISS method propounded by the WKPP, over much resistance, for unknown reasons.
