The WALNUT & POPLAR box call is able to produce the most realistic sounds of a hen. These box calls are ready to go right out of the package. Each call is chalked up and tuned right inside our shop before it hits the shelves. This call produces a realistic two note yelp. It has a high front end that breaks over into a raspy backend yelp. This call is pure turkey and it will bring that gobbler into range this spring.
