Deer Call Bowgrunter Plus The Bowgrunter Plus is the WORLD'S only patented "SOCIAL" deer call. All deer are very social by nature and they must verbally communicate with one another throughout their lives regardless of status, or dominance A deer's social verbal communication is so soft and subtle that many hunters fail to hear it. It was this very soft, subtle and once secretive sound that we have duplicated precisely With our "SOCIAL" deer call, you will draw on the deer's curiosity to know "who is there" rather than a fight or flight sound of a loud rutting buck call which may scare deer away in Pre and Post ruts. You WILL call in up to 3 times more deer than before with the Bowgrunter Plus. This call has become known as THE PREMIER deer call for good reason, it produces results. And a weakness to be successfully exploited by hunters.thus creating a deer call that has proven to be extremely effective during the WHOLE season, PRE&lt; PEAK&lt; and POST ruts rather than just during the rut.
