I use a foxpro fury, the baby cottontail/adult cottontail seems to work the best for me. the first time I used it a coyote showed up in less than a minute, and i was not ready. I have called in foxes several times, and have even had then bit my foxpro fury speaker. Im still learning and im looking into night LED lights now.
I called in a field one morning with no luck, then went just inside the woods. I had a black coyote show up quickly, he was just looking at the caller...#4 buckshot peppered him!
