MAD’s patent pending Hyper Growl is the next level in deer call innovation - a call body engineered to emulate the anatomical production of whitetail vocalization. The addition of a ‘Hyper Ventilator Tube’ to the air passageway simulates a deer’s nasal passage or nostrils, creating the most realistic deer sound ever replicated. Featuring a reed system that will not seize, no matter the volume of air used, the innovative design allows the hunter to simply block the end of the main air flow tube in order to create perfect snort-wheezes through the Hyper Ventilation Tube without removing air supply from the call. In essence, both grunts and snort-wheezes can be produced in a single breath. This deadly combination allows the hunter to reach out and grab that monster buck with the loudest, most realistic calling sequences ever achieved.
