The WHISTLER JIG is one of the most prolific lures ever designed for catching all gamefish species. Its secret is a sensitive metallic "propeller" blade that adds flash and sonic vibration to attract fish . . . and provoke em to strike! It helicopters down at half the speed of equally weighted jigs on the fall, and is dynamite in clear and moderately stained water for all game fish species! Just rig it and jig it!
