-244 METERS & HOSPITAL FOR HERBERT NITSCH

I love chat for nothing. That’s why I’m getting involved. The ban on diving with decoration is simply a matter of total ignorance of what… decompression is. This is why we can in no case invoke security to impose this kind of stupid rule. If someone here can answer the following question, then he can justify the absurd measures that Marie-Aline rightly speaks of, the question? here it is: what is the safety curve? it is a sectarian notion and totally outdated. I say sectarian because it consists in fact in reducing the knowledge of the phenomena of saturation / desaturation to a single chapel, that of PADI in this case. For 12 years, I have been carrying out comparative decompression models for a French magazine and these measurements are rich in lessons. Indeed, on the basis of a typical weekend that we follow scrupulously to be able to compare, we obtain ascent times, because I do not want to limit the desaturation to the levels which are only a form of decompression, the ascent. in itself is just as important, thus total times which go from the simple to the double from one model to another and I speak of models currently on the market. So here is the absurdity of this safety curve story: two divers do strictly the same dive, come on, they hold hands until the time to start the ascent, one goes up with a deep stop RGBM model, Mares or Suunto, it will have to stop, for example, one minute at mid depth, first reprimand, then 5 minutes at 3 m and why not 3 more minutes for the recommended safety stop, the other, which dives with a Océanic in DSAT mode Roger and Powell, the best-selling model in the United States as if by chance, will pass him without stopping and wave hello to him, this dive is very real, I have it in front of me in my tests, their state of saturation is the same, it is only their decompression model that differs. Which one is the safest, to use the argument read in this forum, the one that makes stops or the one that does not for the same dive? If an instructor wants to impose this kind of absurd and ignorant principle, when he goes to the end of the concept and imposes a decompression model, it will at least filter the customers. And the most important thing in all this is to take into account that it has been a long time since we no longer use, in modern systems, this notion of no-stop diving, it does not exist, it does not exist. 'There are only dives with or without a stop in the water, which, ask the doctors, are only preparatory stops for the most important level: the one that begins when you arrive on the boat in a state of over saturation, the proof , you can't fly, you don't have to make any effort, no apnea etc etc ..., so to do, if we want to talk about safety, you might as well arrive on the boat with the most over saturation. limited possible, which means to have done rather a little more than a little less stops in the water. The security argument cannot be used in any way for this kind of discrimination; the only explanation, and I agree with the original author of this post, is a peremptory training that leaves no room for reflection but simply applies standard procedures to the letter.

That said Marie Aline, the Egyptian DPs you are talking about were undoubtedly trained in a hurry and do not yet have the experience that would allow them perhaps to make the difference, you should know that recently the law Egyptian imposes a DP for 8 divers on the boats, where there was often a single guide on a boat of 24 clients, 3 are now needed, so to avoid 3 European salaries, many centers were quick to train in the economy of instructors recruited from among the crews, which I would find quite commendable if we went
