um, no. The no decompression limit concept means that from any point within the the ndl you can go directly to the surface without a stop. As long as you exhale you should stand a resonable chance of not getting bent and not embolizing. It would be nice to maintain 30 fpm, but thats not required. The "every dive is a deco dive" menas that you on gass and off gas during every dive; in a perfect world you dont blow and go at all, but if you have to, you can, inside the ndl. thats the whole concept and it has served diving reasonably well. It would be better if you didnt need to blow and go ever because you did the things you need to prevent this from occuring< buddy, redundant system,etc>but UP is always GOOD. Having participated in a rescue where tyhe victim lost his weigths at the bottom, and stayed there after he panicked and spit out his reg despite wearing a foam drysuit< he told us so after we revived him>, i can tell you that when faced with the choice of drowning because i cant ditch any of my weight and my pony is empty vs toss all my shit and live like a pretzel, im going to Littiz, Pennsylvannia every time.< Littiz PA , btw is the home of the pretzel.> Besides this is all academic if you remember to pay attention to your gear < ie weight belt> during the dive, just like you need to monitor the spg, the timer, not get entangled, not get lost, clear you mask etc etc etc. Im not going to touch the rest of your post with a ten foot spear. Sounds like you might want to take a trip to Georgisits or Lonsdale, they are dir guys on the west coast i believe. good luck, Al Marvelli Paul Braunbehrens wrote: > Every dive is a deco dive, right?
