While the presumed 3.5 million man hours on the CCR-1000 line is an 
impressively long track record some would say it is not an enviable 
track record.  Personally I don't know, and I have put in some effort
trying find out.  

I also expect that this 3.5 million man hours is not significantly 
longer than the time spent on the various Drager semiclosed constant 
mass flow units which predate the Atlantis I.

The Odyssey is a larger step from it's antecedents than either the CCR500
or the Atlantis I.  However it is similar in concept to the AGA ACSC which
I expect has enough hours in the water to prove (or disprove) the concept 
of depth compensated volume fraction.

If you're refering to our breather it does have a PPO2 meter.  We're not
crazy!

We expect to be running tests on ours this Sunday.  As always I will 
let this list know what the results are.
