At Primos they have studied the recent interest in hand blown gobble calls. They are effective if you can master them. Truthfully, few can. Primos has worked hard on the Double Gobble Mouth Turkey Call to produce a hand blown call that is easy to use. Realizing that some hunters would not master the hand blown call, Primos pushed on to make sure everyone would be able to use this call. They added the ability to attach a bellow tube to the mouth piece which makes producing a Jake or Mature Gobble easy as apple pie on Thanksgiving! The Double Gobble is perfect for challenging gobblers to come in or locating them. No matter how you use it, the Double Gobble Speaks the language of the gobbler. Primos Double Gobble Mouth Turkey Call Features: 2 ways to gobble – by mouth or by hand One-handed (shake) for jake gobbles Two-handed (pump) for mature gobbles Patented silencer cap
