I've been friends with David Leonard for about 10 years now. When I first met him,he would always show me cool stuff he made in his wood working shop as a hobby. After 2 years of me begging him to make me a grunt call,he finally did and the rest is history; he ain't looked back since. I've prob purchased 6 or 7 over the years for other people and have a few for myself. It's the best sounding call I've ever used. His are also tunable as well. If you slide the band all the way down the reed,it even makes a great doe bleet. Here's a vid of a 115/120" 8 coming to me on a string 2 days ago 3 minutes after I did a tending grunt sequence. He came to 5 yards and circled my tree 3x. I do not use bait either,so really no other reason he came to me other than looking for another buck.
