While a small amount (typically a tenth) of the exhaled breathing gas is released into the water, -a small amount of fresh gas is released from the diving gas cylinder. +a small amount of fresh gas is released from the driving gas cylinder. A diver using a single cylinder of breathing gas can therefore dive for much longer periods than using a recreational open-circuit configuration. With pSCR equipment, a very small amount of breathing -gas is released every time the diver exhales. With active SCR (aSCR) equipment, in contrast, a small amount of -breathing gas is released continuously from the diving cylinder. +gas is released every time the diver inhales. With active SCR (aSCR) equipment, in contrast, a small amount of +breathing gas is released continuously from the driving cylinder. To log pSCR dives, no special procedures are required.
