if you know there will be other hunters possibly close by, leave the decoys at home, assuming you have decoys. be the first one there, and get about 200 yards from where you think they are roosting and try to get them to gobble. open your mouth and listen. you can hear better with your mouth open, dunno why, ya jus can. if you get an answer, shock em again and try and pinpoint thier loc. and move in closer and set up. now the the hard part, if you dont get a answer at all, try a different shock call, if that dosnt work, get closer, maybe by another 50 yds, and shock em again. hopefully you hear something. go slow and dont wear out your owl call, do more listening than calling and dont be afraid to shine your flashlight in other hunters faces, you dont want them near you and they dont want you near them either. well i aint no pro but thats the way id do it. good luck!
