To Those Who Have The Rebreather Itch:
As some of you out there might have read in Rod's article posted a few 
months back on techdiver as well as in Aquacorps Magazine the two of us each 
came into  the possession of a CR155, the civilian model of the Biomarine 
Mixed Gas Rebreather. I've currently got about 11k into it. This includes 
it's purchase, training, and re-plumbing to add a bail out reg and or BC 
inflator. 
The biggest problem I've had so far is finding a regulator that would handle 
230 psi of intermediate pressure. (if any of you out there have any ideas I 
would be glad to hear about what you think might work). Anyways getting back 
to the subject at hand; after spending 3 days at TEK and seeing all of the 
units that were on the market or about to go on the market I thank my lucky 
stars that I bought a CR155. It is smaller, easier, less cumbersom, does not 
have 10 extra gizmos to keep track of and it is a closed circut electronicly 
controlled unit with manual overide. Yea the Cis-lunar is supposed to be the 
cats ass but how many of you out there actually have title to one, and those 
of you who put a deposit on one when are you really going to get it?  15k 
plus 3k for training plus annual services, who needs it? I can rip this 
thing apart and put it back together by myself with the exception of the 
electronics. Any competent EE can be hired to fix that for me. As far as the 
rest of the manufacturers out there  they are to worried about the liability 
factor. Unfortunately the've got good reason to be. 

The Prism, I suppose, if you want a semi closed  system. It won't work for 
me I need stealth and time at depth, I make natural history films. Every 3rd 
or 4th breath is going to freak the Hammer Heads, or the Spotted Sea Trouts. 
Six hours of bottom time is plenty and the CR155 has it. I didn't mean to be 
so wordy but its pay back for the last three months of email that I've been 
reading here on techdiver. Hey Rod this is not an advertisement. Oh by the 
way for the next 30 days I'll be in Fiji filming underwater using my CR155
so direct any questions you might have to rodfarb@ce*.co*

See ya
