I never go deer hunting without a grunt call. Can't count the number of times that I've turned around a buck that was out of bow range and headed away from me, and had them come in on a string. Also, works great to bring attention to a decoy if your using one. Of course, I've had other deer stop and listen and keep on trucking. My favorite is still the old Hunters Specialties True Talker. A little bit on the large size but simple and seems to work on the deer and doesn't freeze up. I think they actually just started making it again.
