The nascence of recreational rebreathers was just waiting to happen. Spurred on by rapid advances in technical diving, new materials and technology, coupled with cost reductions, the allure of long and quiet dives, with vastly improved non-deco times, had to seep from the technical communities to recreational diving, leading to the design of a new generation of closed circuit rebreathers aimed primarily at recreational divers.
When I started scuba diving, I became aware of the limitations of an injured body. Every time I carried a scuba tank, the acute pain in my lower back and shoulders increased, and it took a long time for the pain to go away. I did not want to give up scuba diving, so I looked for a solution and found one—diving sidemount.
