I was just wondering, as I met a coyote hunter from Montana that has really thick one reed calls for sale he uses to call turkeys, and coyotes.....he taught me how to call a coyote with one......just wanted some more I guess.....lol....and I can do it on a double reed as well....if your wondering, make a "huff" "huff" sound starting with a pretty good open mouth, then you can bring it to a howl at high pitch...sounds like a young yote...............al
