Knight & Hale’s Fire’n Ice™ turkey diaphragm call does it all in the turkey woods – yelp, cutt, purr and all the rest – and it does it with true tones and versatile volume. It could be the only turkey diaphragm you’ll use all season long. This high-quality diaphragm features Harold Knight’s favorite style, featuring a .004 custom blended blue latex top reed and two .003 latex bottom reeds. The bottom reed features the famous moon cut. Plus, the Fire’n Ice is built with a new custom-blended latex that is more water resistant, resulting in a longer life and a pure tone hunt after hunt.
