Introduced in 1958, this was the first produced regulator for using only one-hose and set a new standard for diving regulators. The standard diaphragm regulator allows water into the mainspring chamber so that the diaphragm can perform transmission of pressure changes.The Cyklon Classic first stage has adapted with time, while maintaining the simplicity and robustness that made it a hit in the first place. If you want a reliable, high performance regulator with more than 60 years of work put into it, look no further.
