Phelps Omega 2.0 Grunt Snort Wheeze Deer Call - The Phelps Omega 2.0 Grunt Deer Call is tuned to sound like a young buck but can be adjusted to your desired vocalization. Nobody likes their grunt call to freeze up with condensation during a cold snap, so Phelps installed a special weighted anti-stick reed for cold weather calling. The internals into an acrylic barrel to make an uncompromising buck grunter.
