The Tech 3 has a split top reed for crisp cutts and high pitched raspy yelping. The Tech 3 features Infinity Latex, which is designed specifically for use in mouth calls. Infinity Latex has the most consistent thickness of any call material on the market. Coupled with the patented Premium Flex process, in which the latex is computer stretched and locked into place, the Infinity Latex calls "come alive" with unequalled sound quality. The calls are all laser printed with the model name so hunters can quickly pick the proper call while hunting.
