The concept of the Freak is great. You can strap it to your leg or you can also strap it to the stock of your gun. As far as the call itself goes, its ok, I would suggest buying a Peg Pack to go with it. I have found that the Pegs/Strikers that they have with the call is not always the best. I guess its a matter of preference to the sounds that you like and want out of the call.
There is a manufacture out there that will allow you to basically do the same thing with the slate calls that you may already have. If I’m thinking correctly I believe that it might be H.S. This is a good option for the hunter that already has a call that hey likes.
Good Luck and Good Hunting
