The Hyper Growl by MAD emulates the actual way that deer produce
sound. The "Hyper Ventilator Tube" attached to the air passageway
simulates a deer's nasal passage or nostrils. This creates the most
realistic deer sounds ever recorded. The special reed system cannot
be locked up, even with as much air flow as you can give it. The
integrated system allows the hunter to place his hand over the end
of the main air flow to create perfect snort-wheezes 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.
