ABSTRACT:
Disclosed is a safety stop anchor including a buoy distantly connected to a diver via a fixing rope. Before the diver returns to the surface, the buoy helps the diver to easily and relaxedly stay at the required safety decompression stop or stops to avoid the caisson disease. A buoyancy control valve is provided on the buoy so that heavy loads can be more easily carried underwater by a neutral buoyancy and to ascend to the water surface.
