Use this Bag of Tricks Combo Pack from Flextone to create buck, doe and fawn sounds. Includes Bone Bag & All-N-One Boned Up grunt call. There are people who talk about getting things done. And then there are people who see opportunity, roll up their sleeves, and do it. The Flextone brand has been developed and improved over the years by a long line of doers who are never fully satisfied with available game call options. Whether it's due to unnatural and ineffective performance, highly adaptive animals, or out-of-reach price points, Flextone was created to continually put performance-driven calls into the hands (and mouths) of hunters.
