Si Robertson has a passion for turkey hunting. That's why Flextone teamed up with him to design the Si Cut Turkey Diaphragm Calls. With a popular "V" cut on top .004" latex reed and two thin .003" latex reeds, this call easily breaks over with sweet sounding two-tone notes, just like those from adult hens. Extra backbone delivers loud commanding yelps and cutts or tone it down for seductive mating yelps, clucks or purrs. Made in USA.
