I had one a few years ago, and it worked very well. I recomended it to a guy at Bass Pro the other day because he was a beginner to calling and he needed something easy to use. Like bobgobble said, strike it on a rock or your knee for more realistic, consistent calling. Just play with it until you get the right tone and sound. I just got fang diaphram from H.S. Stut. Has anybody had any luck with them yet?
