I like it becuase it's loud - I also try to have a 'basic' grunt call along as well...

For example last year I could see a buck on the other side of a picked corn field working a fence line (for sure he was rutting) - long long ways away. Was able to get his attention by doing some super loud grunts... He jerked his head up and starting trotting my way.

There was no way that my 'normal' grunt call could have gotten his attention - just isn't loud enough...

Just another call to have in the bag of tricks...
