The Buck Roar is the most effective deer call since "THE CAN". The "Roar" sounds like a deep, resonating growl that is made by aggressive bucks during the rut. Bucks make this "Roaring" sound when their testosterone levels are through the roof. Whether the rut is in full swing or just beginning, bucks will make the "Roar" when they are trying to get an Estrus doe to stop or warn other bucks to get away from a 'hot' doe. The Buck Roar is made from rubber so that it makes no sound if you happen to bump it on something while you are in your deer stand. In addition to making the 'Roaring' sound bucks make during the rut, this call also make perfect grunts and the snort-wheeze. This call also comes with a 30 minute instructional mini DVD.
