ABSTRACT:
A recovery buoy which is carried underwater by a diver and comprises an indented spool-like body of lightweight material around which is wrapped a cord. A weight is detachably mounted to the body and is attached to the cord so that the weight end of the cord can be attached to a structure to be recovered or marked, and when the body is released, its buoyancy causes it to rise, thereby unspooling the cord.
