I think of it this way. Suppose you are running a company that makes a deer grunt call. Your market research shows that most deer hunters already own a grunt call or two, and that maybe 5% of the hunters they contact are in the market for another grunt call. What do you do? Do you just hunker down, fire half your employees, and scrape along hoping you can sell enough calls toget by? Or, do you go out there and invent some new deer vocalization that none of the existing calls can duplicate?

Think of any other business in the world, what do they do? Well, I'll tell you what they do, they invent some new product to revive their sales.

In my opinion this process has been going on for a while in the hunting industry in general, and in call manufacturing in particular.

I'm not saying there is no such thing as a "buck growl". I am saying I've never heard it. I won't be buying one. I still don't own a grunt tube, either, because any moron can make a buck grunt with his throat if he works at it for about five minutes. (I've grunted in a number of bucks this way.) I did buy the deer bleat can and got another family member to do the same. After two years of use, we have stopped taking our bleat cans into the woods, since the practical result is that two out of three times we've used it, the deer ran away like a pterydactyl was after them.
