In my humble opinion, the book is a good source of information, but some of
the material about safety and cleaning of components and cylinders while
mixing nitrox is incorrect and might downplay some of the more important
aspects of handling oxygen. This is especially important becuase as
technical divers we usullay blend at higher concentration or great pressures
than most recreational blenders. Also, some of the information on how to
forge documents can get you into some serious trouble if there was an
accident or site inspection at your shop or wherever you fill. Don't break
the law, especially Federal Laws.

If you are really interested in blending, take a blending course. The TDI
Advanced blending course is really thorough and would give you all the
background and safety precautions and protocols that you would need to
safely mix gas. From recreational nitrox to technical nitrox to trimix. A
proper blending class is a msut if you are going to do it professionallly.
And if just for yourself and your dive bud, aren't you worth a Saturday in
the classroom ?

The Oxy Hackers book would be a good companion to the TDI text because it
would give you part numbers, sources and distributors for all the equipment
you need. How to plumb and some short cuts and easy formulas.

I keep those two books and my ANDI and IANTD manuals in my garage, which I
affectionately refer to as my PADI "no-star" facility. I blend once a week
and usually make four to eight cylinders, have been for a little more than
three years.

Blend safely, don't let anything go BOOM !!!
