The SweetWater Howler is an all in one type call. It can vocalize rabbit distress sounds and cries, coyote, elk bugle, deer grunt, sand hill crane, and duck calls at a slightly higher pitch. This call can be used for coyote, fox, bobcat, and all other pedators. This call produces all call and vocolizations at a higher pitch, mimicking a female call. Which can be more effective in many cases hunting predators, creating a less intimidating call. Call is 8 1/4" in length.
