ABSTRACT:
A portable self-setting marker buoy (10) comprises an elongate float body (12) having a pair of spherical end portions (14) secured to opposite ends of a tubular intermediate portion (16), to which one end of a line (20) is attached. A sinker (24) is attached to the other end of the line (20). Laterally projecting paddles (18) stabilize the body (12) to minimize drifting of the buoy after it has been thrown into the water and the line (20) unwinds as the sinker (24) hits bottom. An internal battery operated light source (26) is preferably included for illuminating the buoy during periods of low visibility or darkness.
