All predators respond readily to the distress cries of small prey animals. The Sceery Double Barrel "open reed" predator calls can produce super attractive, screaming distress sounds of small prey animals, from small rodents to the larger jackrabbits and snowshoe hares. With the double-sound channels and unique reed, you will be able to produce loud and erratic distress sounds, which are super effective for calling all predators, and you can also produce high pitched coaxing sounds. Making erratic distress sounds has proven to be very productive for calling all predators.
