Abstract: An arrow including a shaft, a head affixed to the shaft and being formed of an elastomeric material, and a marker receptacle formed at an end of the head opposite the shaft. The marker receptacle serves to receive a marker material and to release the marker material upon contact between the head and a target. The head is a truncated cone having a narrow end attached to the shaft. A cavity is formed in the head opposite to the shaft and opens to the surface of the head opposite the shaft. The marker receptacle is deformable so as to release the marker material. The marker is viscous paint which adheres to the target upon contact with the target.

Abstract: An apparatus for controlling the movement of a group of duck decoys having a decoy support frame attached at one end to an anchored elastic band and at its other end to a line which is attached to a reel and motor. Movement of the decoys is controlled by a voltage controlled timer which turns on and off at variable time intervals. The voltage is generated by the backspin on the motor shaft caused by contraction of the elastic band which has been stretched while the motor is turned on.
