I carry 3 locators with me. Actually 5 now that I think about it! I have a Barred Owl Hoot'n tube from Hooks Calls. I have a crow call from them as well. I also have a Knight & Hale Screaming Hawk that is the exact same thing as a woodpecker and wood duck, it just depends on how you blow it and what rythm you use. So, 3 calls in 1 I suppose. I've had gobblers respond to all of them at one point or another.
