Primos Moose Horn Cow Call Open-Reed Moose Call

The Primos Moose Horn is an open-reed style moose call designed to reproduce the mating call of an estrus cow. Its unique "hose in horn" design automatically produces deep, guttural moans of rutting cows. The call is 100% freezeproof, making it reliable in cold-weather hunting conditions. Includes an instructional CD explaining how to reproduce estrus moans and how to use your voice to imitate bull grunts. U.S. Patent No. 5910039.
