Dear All, happy new year, Since I am new to this list (since the end of december) a short introduction: Gerard Wijnsma - Gerry for those who can't pronounce it like I want :-) Dutch About 400 dives, most of them recreational. I am beginning to get some technical interest, doing wreckdives and (slightly) deeper ones. Very much interested in the DIR concept. a remark on this: > > > --- kirvine@sa*.ne* wrote: >One big problem with steel tanks is that they will >pas hydro pretty much no matter what since they tend >to stretch and stay that way, so then do not show the >overstretch and failure to return in the hyrostatic >test. In the Netherlands, during a hydro, not only is checked if the tank survives, but there is also a maximum of stretching, which is measured during the test. I find it hard to believe that this isn't the case in the states. Something else... and although not a PADI diver, is the latest thread not more something for rec.scuba? I am subscribing to this list to learn something, not to hear the usual we're good and you're not - shit. An attitude like that is not DIR, it is dogmatic. I thougt the concept of DIR (apart from reduce to the max) was thinking things trough. A friend of mine is GUE trained, and uses it also for his open water diving. So I am slightly familiar whit it and yes I read the site. Although I embrace the concept of DIR, i am a bit of a jackass, I want to know the reason for something, not just "do this because wesayso". And to top things of with a question: how realistic is breaking a acrylic cannister (primary) in cold water (approx 5 - 10 degrees C). I am thinking of buying one, but have in mind the story of a shattered camera housing from the father of another friend that still lies at the site (the housing). All the best...
