well in about 18 days im going to be doing some experimenting with the Buck Growl. MAD Calls believes that you wont get any results with this call untill lateOctober-Mid November. I think they are wrong and am going to tryusing it off and on through Sept. I have played around with it a bit and like the way it sounds. If you havent heard the call or seen the call go to the website and watch the video here. http://www.obsessionarchery.com/buck-growl-mad-calls-p-830.html
