The Hands Free Hammer can reproduce a whitetail buck grunt as well as doe and fawn bleats. The Hands Free Hammer will not freeze up. To grunt, simply put the oval mouthpiece between your lips and gently blow air over the reed. To bleat, just place your lower front teeth on the slot in the sounding board with your upper lip on the reed, gently blow air across the reed and move your upper lip until you hear the sound you are trying to imitate. Minimize your movement, maximize your calling effectiveness.
