Hunters of all skill levels can elevate their elk calling game with Wayne Carlton's Calls Tone Trough Diaphragm line. As Wayne Carlton himself says, "It’s a revolution in elk diaphragm calling." This innovative call features a built-in sound chamber, known as the tone trough, which allows you to produce great sounds with minimal pressure. Utilizing high-quality Infinity Latex, each Tone Trough call is not only easier to blow but also boasts superior durability compared to other types of latex. The reduced pressure prolongs the life of both the reed and the call, ensuring long-lasting performance. The Premium Flex frame guarantees a consistent fit and stretch from call to call, while the tone trough's sound chamber produces the highest-pitched elk bugles and the most authentic, nasally cow calls available. The Double Reed version adds depth to your calls, enabling you to accurately mimic the vocalizations of both mature bulls and cows with unmatched realism. Whether you're a novice or an experienced hunter, Wayne Carlton's Tone Trough Diaphragm calls will become an essential part of your elk calling arsenal.
