3-Pack (1 Slayer Straight Double, 1 Slayer Split Triple, and 1 Slayer Center Cut Triple) It’s no secret. There’s a learning curve connected with using diaphragm (mouth) turkey calls properly. And the first part of the equation is choosing the right call — a tool that allows you versatility in the field, yet isn’t hard to blow! Slayer Calls has taken the mystery out of mouth calling for wild turkeys, with their Spring Training 3-pack. Included is the Slayer Straight Double, with its twin precision-stretched reeds; Slayer Split Triple, a three-reed call that sounds incredible, while remaining user-friendly; and the Slayer Center Cut Triple, a start-to-finish mouth call capable of producing raspy yelps, clear kee-kee runs and everything in between. Hit a homer with Slayer’s Spring Training turkey diaphragm kit this year!
