I have had pretty good luck with the owl call on the private land I hunt but they dont seem to respond well on the public areas. Could be that everyone is using them. Buy several calls, woodpecker, crow, coyote, peacock etc. and try em all.
In one area I hunt the turkeys shock to the peacock or nothing at all. Another area 30 miles down the road they seem to respond to the crow call best. I dont know why. Sometimes you cant shock them with anything.
