Well that's good to know Mike.
I suppose that the other aspect of all this is that a diver displaying such poor technique could just be considered as lacking control and therefore constituting a risk to both himself and others. A dive centre could use this as a valid reason to ask such a diver to not carry a camera and to dive with an instructor until better skills were displayed. Not an easy task ..... I remember one of our local dive boat skippers explaining how he had watched a hungover 'techie' trying to assemble his gear one morning. After a few minutes he went over to the guy and said that in his state he "needn't bother fitting it together because you aren't going to be diving off my boat anyway"! Its not something that many operators or skippers will do, but IMHO the skipper actually went up in most diver's estimation and I for one will use his boat in preference to others.
On another note, do you remember those Olympus housings you let me have? Well one is still going strong and being used by an author to take (mostly wreck) shots to illustrate his books. It now looks even better used!
