I see this is an old post but oh well. I bought the buck growl just before the 2008 season. I didn't really use it until the rut had set in pretty good. The first morning that I used it in the pre dawn darkness i could barely make out a small buck chasing a doe out in a small pasture that I was hunting over. I decided that I would try the growl right at legal hours. In less than 3 minutes I had 5 small 1 1/2 yr old bucks and what looked to be about 3 1/2 yr old or better buck. I am still learning to age on the hoof, It was definately one of the best built deer I have ever seen as far as sheer size goes. It was pretty amazing how well it worked that morning. I have since got the attention of a few bucks with it just grunting, I have also seemingly scared some smaller deer off, I am thinking that was because of how deep of a tone the call can be. I still carry it with me but would not be opposed to finding a new tube for just grunting.
