Sure-Shot pioneered the duck call market by being the inventor of the double reed call. The Patented double reed design, (which was designed by James "Cowboy" Fernandez and George Yentzen back in 50's) was ahead of it's time back then and is still unmatched today. Sixteen years later when the patent ran out, every other game call manufacturer jumped on the Double Reed bandwagon. Today Sure-Shot still makes their duck calls with that same, once patented, Double Reed design. Including other genres such as goose, deer, turkey, and predator.
