what I can tell is that the instructors were highly qualified, most of them with more than 30+ years of technical diving experience.
As opposed to Dr Simon Mitchell, one of the world's pre-eminent hyperbaric specialists, who also has done a couple of dives?
A good instructor will have read a few papers and maybe a book or two. Simon Mitchell probably wrote them. See the difference?
