Abstract
A decoy fin has a unitary body divided into at least three generally planar sections. These sections combine to form a generally helical surface which, when submerged in fluid moving relative thereto, will generate cyclical oscillatory movement. In one manifestation, the decoy fin is coupled through one tether line to an avian decoy such as a duck or goose decoy, and is coupled through a second tether line to an anchor. Consequently, when the combination anchor, decoy fin, decoy and tether lines are immersed in moving water, such as a stream or river, the decoy fin is operative to move the decoy therewith through an oscillatory pattern. The decoy fin is adaptable to application to a number of different types and sizes of avian decoys, and may also be readily adapted for use with fishing lures or for other decoys.
