Small enough to fit in a pocket. The Li'l Strut Natural Box Call from H.S. Strut features the patented "Silencer Plus" locking device which restricts all sound when walking. The Li'l Strut Box Call is waterproofed and has a natural wood sealed finish with laser engraving. Effectively produces the calls of a higher-pitched raspy hen on one side and a lower-pitched raspy old hen on the other side with greater volume for greater distances.
