ABSTRACT:
A signalling device for underwater divers, in the form of an inflatable bladder held within a container and attached to a reel. The device can be attached to a diver, being strapped to his arm or to his air tank, for example. The device can be actuated by pulling a handle, which releases a gas cartridge to inflate the bladder as it is simultaneously released from the container to float to the surface. Rescuers can then follow the line down to the reel to locate the diver.
