OK let's put the otherside...
But nitrox really is that simple.
If you have the MOD chalked on the tank and you dive a site where the seabed is no deeper it's safer than air.
If you aren't using it to extend your bottom times it's lots safer than air.If you want them you pay for them.
I bet the guide is kicking himself that he missed a sale there.
I admit that I wouldn't enter the water without something to say how deep I am but these people had already agreed to it.
Nitrox doesn't make it more stupid.42m I can see a problem with but 32m is a safe depth. 1.34bar ppO2 isn't much.And look a fool?I hope so. Nitrox needs demystifying and using not treating like the black art from hell.
HTH
I agree with you about your last point, but i feel that your post does very little to help with that, as you seem to saying that the behaviour of this centre is sort of OK.
What you seem to be missing is that these divers, who were customers of this school, had by the sounds of it a very crap introduction to the black art of EANx. They also seem to have paid a lot, and not received, on the face of it, a course that would prepair them properly to use EANX.
Not being given depth gauges or computers is criminal as far as i am concerned, you wouldnt dive without a way of measuring and recording depth, i dont, and wouldnt. Why is OK for students under instruction to do so, i think you would find that PADI would have a very very dim veiw of this little episode.
As a working instructor i get total pissed of with this standard of instruction being delevered to student who know no better. It is time for it to end.
My final point, the cut price, bargin basement aproach to the SCUBA industry does not help this, How many instructors do you know who have been doing it for over ten years, that are over fourty, not too many i guess, most of the divers i train to be Instructors only plan to do it for a few years, no money is the reason.
