The Primos Clear Cutter Box Call makes clear and crisp hen cuts and clucks. Allowing your thumb to rest in the groove to act as a spring with slight paddle resistance, simply slap the edge of the paddle to produce the sounds a gobbler can’t resist. For yelps that start high and roll off to a raspy low finish, just pull the easy to work paddle over the pre-tuned box. The Ergonomic box and paddle is made of premium mahogany and walnut wood.
