They may include additional cylinders for decompression gas or emergency breathing gas.
Closed-circuit or semi-closed circuit rebreather scuba systems allow recycling of exhaled gases.
The volume of gas used is reduced compared to that of open circuit; therefore, a smaller cylinder or cylinders, may be used for an equivalent dive duration.
They far extend the time spent underwater as compared to open circuit for the same gas consumption.Rebreathers produce fewer bubbles and less noise than scuba which makes them attractive to covert military divers to avoid detection, scientific divers to avoid disturbing marine animals, and media divers to avoid bubble interference.
