Hi Martin
I've separated your comments from mine with '***' because the lines
went crazy with '>'s  :)

Jason, I guess in principle what you are saying is that Nitrox 32 bought from
a shop is exactly the same as nitrox 32 you mixed in  your shed, and of
course, provided you use the correct gases and materials of course it is.
However, if you don't know how to mix gas, then a)it might not be the same - it
may be analysed incorrectly or contain contaminants, and b) a self taught mixer
may place him or herself at risk by not following safe practices.
Additionally, I would envisage that *most* potential users of nitrox do not
want to mix their own - they will wish to go and buy it, as they do their air
fills.  This means the store needs to invest in equipment, and for volume this
problably means oil free compressors, a mixing panel, storage banks etc. -
a lot of dollars. Therefore, somewhere along the line, if we wish other divers
(less technically able than yourself?) to be able to take advantage of our
new gases, the dive industry needs to be able to make some money so they
are *able* to expand their facilities. I guess they also need to eat and
pay the mortgage as well, or isn't that allowed?

Are you saying that the diving industry should operate as a *charity*?????

Also, it would seem that most of the information that we currently use has
come in one form or another from the "private" agencies or the people
behind them, and so we should bear that in mind when we give these guys a
hard time.

It 'seems', as you put it, to have come from the private organisations
because that is how they like to portray it.  The information has been
around the commercial industry for *years*.  All anyone had to do was
go out and get it.  That's what the 'dive gods' did.  They didn't make
it up.  I haven't heard of *any* tech dive organisation that has done
*any* research into diving.  They have ridden on the coat tails of the
commercial and scientific industry.

The only sport orgainisation that has done any research (to my knowledge)
is the often ridiculed PADI.

Cheers Jason :)
