The Ninja Crystal is built into a walnut pot with a YellowHeart soundboard which offers a very true to life turkey sound. This call comes with two hand-matched strikers, one being a YellowHeart/walnut Ninja Stick and the other being hickory that that will offer each hunter the ability to sound like two different hens. The Ninja Crystal produces great two-tone yelps as well as great cutts, cackles, and purrs. This call affords you the ability to call both loud and soft. The Ninja Crystal is a killer call that is soon to be a favorite among turkey hunters nationwide.
