Pull that big buck into range with the soft realistic grunts you get from the MK Unique Designs Hands Free Grunt Deer Call. Especially great for bowhunters/crossbows/gun hunters in heavy woods where shooting distance is limited. This call brings those bucks the last 100 yards. Designed to be held comfortably in a hunter's mouth, this call allows a hunter to produces realistic soft grunts while preparing for the shot. Small plastic with an adjustable sound board. Just move the 'O' ring to one of the settings to change the sound in seconds - no learning curve.
