Well, I'm certainly not an expert, but as I understand it, everyone is using their own proprietary method. Do you subscribe to the TechDiver mailing list? They've discussed CO2 scrubber material before, and there are lots of informed people on that list. (send request to techdiver-request@opal.com with subscribe in message body) Another source of info is to track down some back issues of AquaCorps. Three issues ago (C2) was dedicated to closed-circuit scuba, and I thought I saw an article on CO2 scrubbers in one of the two more recent ones (Hard or Wreckers). -Eric ----------------------------------------------------------------------- Eric Lundquist, Systems Manager School of Oceanography, Box 357940 ericl@oc*.wa*.ed* University of Washington (206) 543-0594 102 ORB Seattle, WA, USA 98195-7940 http://www.ocean.washington.edu/people/staff/ericl/ ----------------------------------------------------------------------- Check out my Puget Sound area scuba diving WWW page! http://diver.ocean.washington.edu
