The Natural Bone Grunt'R uses Flextone's tried-and-true rigid reed system surrounded by a soft, flexible body. This allows callers to easily vary tone and inflection for a natural sound unlike anything heard in other grunt calls. Move the O-ring to transition to doe or fawn sounds, and adjust the expandable hose to move from young to mature buck vocalizations.
