I have hunted since I was 7 years old and to this day I have NEVER heard a buck or doe running around in the woods continually bleeting or grunting. I'm not saying that it will not work but if you expect to call up a buck (or doe), you will be disappointed. If you use it, use VERY sparingly. For example: One bleet then do not use it again for 15-30 minutes. If you spot a buck passing by at a distance I would recommend that you give it a blast loud enough for him to hear it then put it away.
