The Primos® Big Bucks® Bag Rattling System reproduces the sound of a buck fight. With two different types of Power Tines® in the easy to carry bag, you can create a small tussle between young bucks or a full on buck brawl. The new camonet bag helps to increase volume and everything is 100% waterproof for flexibility of use. With the Big Bucks® Bag, other hunters may come running because the sound is so realistic.
