My list server has been down all day as far as receiving incoming mail is
concerned.  However, I'm still able to access the archives via the web so
can read the posted messages there.  What, of course, this means is that
instead of taking 'brain breaks', I've been head down finishing a couple of
overdue articles.  One of which relates to regulators.  (I noticed that Brad
asked for information.)

After ploughing through all of the literature from the DEMA Show, I'm
starting to run out of superlatives to describe each of the new - and as yet
untested by me - models.<BWG>   Something that I did, however find
interesting related to Atomic Aquatics', all titanium regulator.  The
original model was launched a few years back, since when a couple of other
manufacturers have also produced titanium models.

Both they and Genesis - another manufacturer of a titanium regulator -
describe their regulators as being compatible with oxygen enriched air
mixtures.

A little later I came upon the Mares brochure that talks about their new
'Ti-Planet' - a regulator with titanium first and second stage parts.  I was
particularly interested in the little box at the bottom of the page that
read:  "Warning.  Titanium is incompatible with oxygen-rich environments,
therefore the Ti-Planet should not be used with nitrox breathing mixtures."

I've never before given much thought to those materials used in the
construction of regulators - but perhaps it's time to do so!  :-)

Have a great week-end all of you.  I'm heading north for a couple of days -
by which time my list server will, hopefully, have sorted out the problems.
:-)
