The Nordik Grunter Deer Call was developed specially for calling whitetail deer. The sound may be adjusted by pulling the tube apart or pushing it together. With a compressed tube this call produces a lighter tone that imitates younger bucks. With a protracted tube deeper tones are made to attract older bucks, but may scare away younger bucks. The Nordik Grunter is excellent for making contact grunts and tending grunts.
