The Primos Buck Roar Deer Call creates a deep, resonating roar made by aggressive bucks during the rut. This signals the estrus doe to stop or warns other bucks to stay away. Since the call is made of rubber, it won't make a sound if you accidentally bump it against anything. Along with the roar, this call makes a deer grunt call and the challenge wheeze. This call also has a compass. Made in the U.S.A. Limited lifetime warranty.
