The Snow Goose voice is a challenge to reproduce accurately. To achieve the highs, lows and growls of snow geese, Primos developed the technology to shave a Reed precisely to a certain thickness. The Reed is actually shaved in a tapered fashion. This produces a Reed with a thicker middle for backbone, and a thinner tip for sensitivity and accuracy in sound. The shaved Reed snow takes much less air to blow than other snow calls, with tremendous volume, and overwhelming realism. The accuracy of the sound of the shaved Reed snow call will make a difference on your next hunt. Features: - tremendous volume with little air required - missile-shaped Reed shaved from 9/1000to 14/1000thick - easily reproduces multiple sounds of snow geese to sound like a whole Flock.
