About Closed Circuit Rebreather

A rebreather is a breathing device that recycles a divers exhaled breath, scrubs it clean of carbon dioxide and recycles that same breath so that the diver may use it over and over through out their dive. Rebreathers are different from open circuit SCUBA, because rather than exhaling the waste product (carbon dioxide) as bubbles through your regulator, the carbon dioxide is scrubbed out and converted back into breathable gas (so there are no bubbles!).

 

*NOTE* Please keep in mind that each CCR course is specific to a particular rebreather unit. There is no general CCR course.
