RU>Although I am a "newbie" it doesn't seem that difficult to pick your RU>mix. Why not plan your descent, travel, ascent, and stop mixes to keep RU>the ppO2 at a safe level? IMHO The best part about increased technology and RU>knowledge is that it allows us to dive more safely even at the extremes! It's not a point of being difficult to pick your mix, the issue comes down to perceptions of safety and weighing those against the risks of what you are trying to achieve. If we wanted safe - we wouldn't dive, pure and simple. But we have decided that the benefits of diving outweigh the risks involved. Recreational divers looking for safety should not go beyond 30 fsw, then there will be virtually no DCS and they can have prolonged bottom time. Many of us diving what is termed Technical or Extreme Exposure Diving have our goals and we strive to achieve those as safely as is REALISTICALLY possible. There is nothing macho involved here. I am not trying to dive technically, I am trying to dive simply. Yes I understand there are limitations. I heard it stated when I started diving that PpO2 of 2.0 were acceptable. That has dropped to 1.8, then 1.6. Now 1.4? If safety, TRUE safety, is your concern, you should remember that underwater is an HOSTILE environment. Yes we should be as safe as we can, but if safety is your goal regardless of cost AND you decide to continue to dive, get yourself a submersible and try not to crash into anything. But if we need standards to dive deep, as Win suggests, the commercial divers have standards that ARE safe and they have suggested we adopt them if we wish to dive SAFELY. That means full face masks (so you can't spit out your reg in a convulsion or blackout), tether to the surface, handler for each diver, on site recompression chamber, on site medical staff for deeep dives, etc. ad nauseum. Perhaps DeepTek will outfit all of us or else they may suggest that if you can't foot the bill, you shouldn't be in the water. Personally, I don't like people making standards for my safety, I'm a big boy now. MRWConsult@ex*.co* /\/\/ --- � DeLuxe� 1.25 #11829 � Silly Humans . . .
