Abstract: A diver awareness buoy for signaling the presence of scuba divers diving underwater within a general diving area including a base and an inflatable bladder having a main body. The main body has a humanoid configuration including a torso section and a head section simulating the upper body of a scuba diver present in water. The torso section includes torso indicia corresponding to the signal for signaling that a scuba diver is beneath the water surface. A ballast is carried by the inflatable bladder for maintaining the buoy in an upright floating position in water.
