Im just getting into predator hunting and haven't had a lot of luck yet, me and a buddy have probably sat 20 different stands in northeast Oklahoma without calling in anything, so we broke down and bought a Foxpro Firestorm. After about 10 different sets we finally called in two using lightning jack but couldn't get a shot because they wouldn't get out of the brush. Any suggestions on what are some of the best sounds for coyote's?
