... The most shocking example was a pair of BSAC divers with 700 + dives, wearing Buddy brand stab jackets, unaware that they were kicking the living hell out of our fan corals here. I've certainly dived with others who hold shiny-new AOW ratings who are just as dangerous to the corals, but I rather expect divers with back-to-back OW/AOW and on their 10th dive to be in a learning curve, and I had much higher expectations of these other folks. Happily, these encounters are not evidence of an overwhelming trend. Again, these are individual failings, not necessarily 'proof' that the BSAC system doesn't work or that OW/AOW as a combo class is a bad idea. ...
Its an unfortunate fact that UK divers think the sea life is more hardy around our coast. The reality is after 50 years of divers kicking the bottom to death many native creatures and plants have become very rare, the pink Sea Fan comes to mind.
