I use cow calls and a bugle here are some of the call I use. I like the Primos Hyer Lip single and the double, the double is great if the elk are way out there, but it'a a littlie harder to use, the single is easyer to use and isgood when they coming in. The Hoochie Mama is good for some elk,butso many people use them(here anyway) I thinkthat some bullsget used to it.I like the Bull Horn to it's easy to use and sounds/works great.
