The Hunter's Specialties H.S. Strut mouth turkey call frame assembly is more comfortable to use and retains its shape and perfect calling pitch. This line of calls produce all the authentic tones of a turkey, from the yelps of an old boss hen to raspy, seductive cackles. These calls utilize H.S. Strut's new Infinity Latex for reeds that require less air pressure to run, giving hunters more realistic sounds. Both the tape and latex are moisture resistant for longer life.
