I use one on occassion with pretty good success- Although I dont just run around shaking that thing everywhere I go-
I did have some guys come in on me after I had gobbled with it a few times once and it scared the u know what out a me , so I'm careful as to when I use and what the circumstances are. They can be used with the fighting Purr and works extremely well when done in that manner with birds that get tight lipped from pressure- Almost every bird I've taken with the gobble call and fighting purr have either come in running and gobbling like a bat out a hell or came slipping in to just take a look, either way they got a face full of Hevishot-
Game over.
