A double counterlung for the breathing circuit of a diver has regulators (41, 51) for automatic addition and venting of breathing gas. Also disclosed is a weighted hinged plate (3) for a double counterlung, to reduce breathing effort when the diver is horizontal. Other improvements to the breathing circuit are described including use of a two stage compressor (151, 155), and single actuator valves for back-up circuits.
