The Ace In The Hole is loud and raspy. These calls produce a sound all their own that have been a favorite of guides and serious duck hunters for many years. These calls produce a barking quack that can be heard at extremely long distances. The farther the distance the more realistic this call sounds. Our Acrylic calls are louder and have more range than the Polycarbonate Keyholes we offer and are tuned to sound exactly the same, only much louder. With a group of buddies hunting in the timber and a cut down in every hand hunting with you. You and your crew can dominate your hunting hole and the hunting holes around you.
