Harold Knight and David Hale started making duck calls in a basement workshop more than 35 years ago, with a goal of making one of the most natural-sounding game calls ever produced. Well, mission accomplished with the Wood Duck Call! The Knight & Hale Wood Duck Call makes the lonesome sounds of the majestic wood duck. This easy-to-use call reproduces the many calls of the wood duck. This call has a rugged, compact design with a built in lanyard ring.
