Abstract:
1. A decoy fin which produces an oscillatory motion when interacting with fluid moving relative thereto, comprising: a unitary body having first and second couplings, and first, second and third generally planar fluid interaction surfaces, said first and second generally planar fluid interaction surfaces angularly offset from each other by an obtuse angle with respect to a first face of said second generally planar fluid interaction surface and said second and third generally planar fluid interaction surfaces angularly offset from each other by an obtuse angle with respect to said first face of said second generally planar fluid interaction surface; a first interface defining a generally linear boundary between said first and said second generally planar fluid interaction surfaces and having a first termination adjacent an outer edge of said unitary body and a second termination adjacent an outer edge of said unitary body distal thereto; and a second interface defining a generally linear boundary between said second and third generally planar fluid interaction surfaces, said second interface angularly offset from said first interface and having a first termination adjacent an outer edge of said unitary body and a second termination adjacent an outer edge of said unitary body distal thereto and thereby defining a distance along said second generally planar fluid interaction surface between said first interface first termination and said second interface first termination which is smaller than a distance along said second generally planar fluid interaction surface between said first interface second termination and said second interface second termination; an anchor coupled to first coupling; and an avian decoy coupled to second coupling; said first coupling formed in said first generally planar fluid interaction surface and located more nearly adjacent to said first interface second termination than said first interface first termination; said second coupling formed in said third generally planar fluid interaction surface and located more nearly adjacent to said second interface first termination than said second interface second termination.
