ABSTRACT:
An adjustable depth marker buoy for marking a spot beneath the surface of water. The buoy includes a float for floating on the surface of the water and a reel assembly disposed in the float. The bottom wall of the float has a weight depending therefrom that maintains an upright orientation for the buoy when it is in the water. The reel assembly includes a spool of anchor line, a non-threaded rod, a threaded rod, a nut assembly that threadably moves along the threaded rod and slidably along the non-threaded rod, and a pointer assembly that moves slidably along the non-threaded rod. When the spot is located, its depth is determined. The pointer assembly is then slide along the non-threaded rod, until its pointer points to depth scale indicia on the depth plate corresponding to the depth of the spot beneath the surface of the water. The anchor line is then wound out until the nut assembly contacts the pointer assembly forming a stop and indicating that the anchor line has been fed out a length equivalent to the depth of the spot beneath the surface of the water. At this point the spool assembly is prevented from further rotation by a lock pin. The buoy is then thrown into the water at the spot causing the anchor weight to engage the bottom of the water and thereby minimize drift of the adjustable depth marker buoy, by virtue of the anchor line having a length equivalent to the depth of the water.
