The Still Grunter does just what the name implies: it allows you to stay still. Time after time, we've wished that our hands were on our bow or gun, rather than on our call. Use the same as other Primos grunt calls or remove the tube and slip into your mouth for hands-free operation. The call is fully adjustable, from throaty buck grunts to lovesick doe bleats. Comes complete with detachable grunt tube and lanyard.
