Disclosed is a safety method and apparatus in connection with SCUBA diving to control a diver's buoyancy. The diver is equipped with diving equipment comprising at least one air pressure tank (1). A valve device (2) is connected to the pressure tank and arranged to supply air from the pressure tank via first supply means (5) to a breathing regulator (4) and via second supply means (9, 12) to an inflatable diving jacket (6). In order to control the diver's buoyancy, an actuator (8) is provided, being able to automatically initiate inflation of the diving jacket when the diver has not affected the air flow through the breathing regulator for a certain time period. The actuator is controlled by an actuation mechanism that automatically sets the actuator in active mode when the diver is within an actuation zone. In order additionally to improve the diver's buoyancy the actuator is also arranged to automatically initiate dumping of a weight (11) carried by the diver when the air flow through the breathing regulator has ceased for a certain time period. |
