ABSTRACT:
A buoyant device used as a marker in the water for use in water sports is disclosed. The buoyant device comprises an inflatable buoyant member having one end coupled to an elastic cord which is coupled to an accompanying anchoring bag that is weighted down. The overall length of the elastic cord is varied according to the depth of the water with a self-locking length adjusting device used to vary the overall length of the elastic cord to eliminate any slack in the elastic cord in shallow waters in which the depth is less than the overall length of the elastic cord and when water currents change.
