We had Dan Martin of Martin Archery up at the Lodge a couple years ago.He and I made a stalk on a group of mulies that included a nice 4x4. Spooked them inadvertently and Dan whips out a little wood call and started blowing it. Everyone of those mulies came back uphill and downwind with in 25 yds. The nice buck stuck his head and part of his neck over the rise in the hill and Dan turned down the shot. Did not want to have him jump the string and not hit him right. . The call was one that Martin Archery sold years ago as a predator call. He sent me three in the mail....They work.
