This is a selection of 2 Hunting Game Calls both marked Knight & Hale LEAD DOG KH942. One is new unused in the packaging and the other is used. I made a extra copy of the instructions from the new one. It makes different sounds based on how the the mouthpiece is inserted. I found this model is still made but in a red type of color while this one is amber or light brown which would be better for camouflage reasons. It is a distress prey call like a rabbit when the reeds are enclosed. When the reeds are open or out it is a Coyote Bobcat or other Predator Call.
