Carl, though in an ideal world, what you say may be true, in practice, 
what you say is wrong. I call your attention to the Sept. 1995 issue of 
National Geographic. Look at Bill Stone's article. The female geologist, 
Am Ende, referred to in photo of a rebreather diver and elsewhere in the 
text, is in fact a newly certified diver with more hours on the 
rebreather (Cis-Lunar) than open circuit. She is a PhD graduate student 
in Geology at The University of North Carolina. She learned to dive for 
the project reported in Nat. Geo. There is a diagram and photo of 
Cis-Lunar unit from which you can build it , probably for about $250.
