With the push of a button, the RubberNeck converts from a mature buck grunt to a young buck grunt or a doe Estrus Bleat. Just like the Power Buck & Doe, there are many times when you think that a buck won't responds to your grunt, it’s because he can’t hear you. For the ultimate tone and volume control, just squeeze the megaphone end. You can use the call with the traditional lanyard around your neck or strap it to your arm for easy accessibility in critical moments. We are excited about having perfected this rubber grunt call for the avid whitetail hunter.
