Double your chances of calling 'em in with the Double Whammy. It howls like a pack of dogs invading on local dogs territory. You can be sure the local pack will come in to run them off and you'll be there waiting for them. You can also create excitement by sounding like multiple animals in distress. This works like ringing the dinner bell at a cookout. Predators can't resist the various distress calls of this double-reed call: the call capabilities are endless. Serenade 'em with the Double Whammy. Includes instructional mini CD.
