Description
The Spring Yelper Box Call is a unique box. Besides its construction of American poplar and walnut, it is a one-sided call with a spring design. The spring is a compression/torsion spring. It not only controls the tuning by way of screw depth but also allows the user a one-handed foolproof operation. One only must stroke, tap or slide to get all of the vocalizations from yelps, cuts, clucks, whines, and purrs.
