Crows will at times stop in the tree overhead of a strutting Tom and Caw their fool head off. So be aware of that. While I have been given a few custom crow calls I love my Haydel plastic crow call as it will let me use it like a wounded crow. Has notches on the mouth piece. If I get bored I can easily call crows from a distance. Best I ahve ever done in the trees above me was 61.....

Other good locator calls are a silent dog whistle, duck or goose call, referee whistle, car horn, air horn, pileated woodpecker, and then I use a gobble call at times.
