The flextone Buck Commander allows you to produce Desperate Doe Estrus Bleats, Dominant Buck Grunts, and Commanding Growls with ease. The large ported exhaust bell gives this call the volume and natural sound to lure pre-rut, rutting, and post rut bucks into range. As always flextone technology produces a more natural sound by accurately mimicking the soft flexible tissue of a deer's neck, mouth, and tongue. It is simple to use, for Hard Core Buck Grunts and Growls just blow into the call without squeezing the barrel. To produce desperate doe estrus bleats and bawls just squeeze the D button on the barrel while blowing. You will also appreciate the soft design if it accidentally contacts your gun or bow.
