The Wild Hog Call from Knight & Hale imitates the grunting sounds of a contented, feeding hogs. The soft contented grunts of the Wild hog Call will draw both boars and herds of sows with their young. The new barrel design has an ergonomic look and feel. The Threadlock barrel threads into the shortened end piece for ease of disassembly. The wedge, reed, and sound board are also changed, so the reed "locks" into place. This allows the call to be reassembled just as it came from the factory - every time. The end result is a great sounding, user friendly, compact call, with a lot of volume.
