| Re: Optima Cartridge I'd love to see it as well. All of the test data I have seen thus far indicates that the cartridges are OK for recreational diving and that is all. Short duration and 0-50m diving.
I am a huge cynic when it comes to the Micropore cartridges and have seen nothing to make me change my mind that they are very early technology that needs a LOT of development to catch up with granular sorb. In every test i have seen they have performed at a level that I deem unsatisfactory.
I still see no advantage in using them in a well designed rebreather as they are expensive, if available and costic coctails have virtually being eliminated by sensible rebreather design (Baffles in T Pieces in OTS lungs)
