Knight & Hale"s Smoke"n Fire turkey diaphragm produces the most-realistic turkey hen sounds of any diaphragm on the market today. The secret is in the wide front and V cutter-style cut. Designed with a custom-blended .004 black latex top reed and two red prophylactic bottom reeds, the new Smoke?n Fire turkey diaphragm call is easy to use and has a raspy, realistic tone. The new custom-blended latex is more water resistant, for a longer life that keeps its true-to-life tone longer.
