Given that all dives are decompression dives, whether taught that way or not, and that DCS is rare it seems to me there is too much emphasis on the need for extensive "special" deco training. Much of what I've read in other venues seems to be more for marketing of a course than something needed.
Now, I'm not an "old time" NAUI diver. But, my initial training was NAUI and even at that level I understood how to use tables to plan a dive, any dive. That a planned stop had to be at some other depth than 15' was of no consequence from a profile planning point of view. A planned dive is a planned dive.
Since then I've been introduced to a variety of thought themes from a variety of teaching agencies. Each has had its' own take on dive planning. But, physics is physics and the characteristics water don't change. So, these have done more to reinforce the idea that from a profile point of view all dives have the same factors; none of which are complicated.
Where the thought train goes astray is mixing in the needs of certain kinds of diving, usually deep, and the desire for faster decompression, usually requiring gas switches. It further goes astray when desired dive methods, such as team diving, are thrown into the mix. Now, we are going beyond the physics of diving to other matters that we have chosen to affect the dive.
So, to me, this is an issue of clear, analytical thinking, not of any special training.
Arctic,
Do you have any technical training? With NAUI-tech or another agency? What levels?
