MAD's new patent pending Hyper Growl makes the next new step in deer call innovation by emulating the actual way that deer produce sound. The addition of a "Hyper Ventilator Tube" to the air passage-way, simulating a deer's nasal passage or nostrils, creates the most realistic deer sounds ever recorded and a reed system that cannot be locked up with as much air flow as you can give it. The integrated system even allows the hunter to place his hand over the end of the main air flow to create perfect snortwheezes through the Hyper Ventilator Tube without removing air supply from the call. This deadly combination allows the hunter to reach out and grab that monster buck with the loudest, most realistic calling sequences ever achieved. By studying the anatomy of whitetail deer, MAD engineers incorporated the nasal/vocal equivalency of the deer in to this patent pending call. The actual nasal chamber whitetails use to create their snort and wheeze vocalizations is assimilated, as well as deep guttural grunts and growls. Not only are the Grunt and Snort Wheeze components connected externally, they also internally share the same air flow. Either or both passages of the Hyper Growl's Hyper Ventilator Tube (nasal cavity) can be plugged with the caller's hand to add tone inflections by altering the air flow, producing Growls and / or Snort Wheeze sounds in seconds. The call can also be operated without any manipulation for superior volume on windy, blustery days. Despite all this technology, this call still produces the old reliable tending grunts and pops so popular in MAD deer calls.
