Was not quite sure where to post this so feel free to move it as nesessary. I did not know Cliff but he was my instructor's very first instructor and he is the co-founder of Silent Diving Systems which distributes both Inspiration & Evolution Closed Circuit Rebreather products. Hense why I posted this in the Rebreather forum.
