Pick yourself up a River Valley Game Calls Deer Flute, with a quick easy slide of the brass slide, you'll have your buck grunts, doe bleats and contact calls. No need for 0rings or placing your fingers just right. It's simple and it's got exceptional sound. I've been calling whitetails nearly 30 years, it's my go to call and I've owned a pile of them.
