The flextone® Dying Jackrabbit? emits incredible natural sounds due to its rubber body. Blowing hard into the mouth piece creates super loud distress screams that can be heard hundreds of yards away. By squeezing on the rubber end and changing its shape creates inflection in the distress cries. It's these pleading sounds that convince the wariest of predators there's an injured jackrabbit. Once the predator commits to your calling, simply pinch or bend over the end and turn the Dying Jackrabbit? into a close range coaxer as you tone down the desired volume and make softer whines.
