Hi All, No need to control the drag! There have been a couple of requests for more details, and I don't have to be asked twice to shoot my mouth off. The most specific request was from Erez who asked: * Profile of the IWR. * What did you use to determine when to get out (computer, a good guess, IWR techniques)? * Did you use a full face mask? * Did you use O2 under water or air or something else? Profile: I went down the pile at the end of the wharf, and stopped when it looked like I was more than 3 metres and less than 6. How I determined when to get out: When I looked down at the O2 cylinder as it sank, and my neck seal unsealed! By that time nothing hurt, I was very bored, and now I had a gallon of cold seawater down my drysuit! Full face mask: No What did I breathe: O2. It was all very ad hoc. That's the charm of O2 IWR. You can just do a bit of it. The need for formality just doesn't seem to be there. With an air IWR you can't just think "well, thats enough then" and get out. You'd most likely die. With O2 there is the possibility of taking a half empty cylinder down and doing what you can with it. (Which is exactly what I did) Air breaks are good, but I doubt that I had more than 30 minutes supply with me, so they weren't really relevant. I could have set myself up better, but I got in the water *first*. I actually had the O2 cylinder in my hand, and a weight belt slung over the shoulders. Pressure first, tidy later. Cheers Jason =:)
