Primos Deadly Double Diaphragm Turkey Call

The Primos Deadly Double Diaphragm Turkey Call is a dual-reed hunting instrument engineered for serious turkey hunters who demand versatility and control in the field. Like a precision fuel injector that adapts to multiple engine conditions, this stacked diaphragm design delivers variable tonal output depending on calling technique and air pressure. Built for both novice and experienced callers, the Deadly Double produces everything from soft, natural yelps to raspy, aggressive cuts—making it a single-call solution for complete turkey communication strategies across multiple hunting situations.

The call's architecture uses two precisely-engineered reeds separated by a 1/16" air gap that prevents reed sticking—a common failure point in single-reed designs. The stack incorporates one ultra-thin latex reed paired with one super-thin prophylactic reed, creating independent vibration zones that interact to produce complex harmonics. This dual-frequency system allows hunters to manipulate tone quality and aggression level through subtle changes in breath control and lip tension, similar to how variable valve timing optimizes engine performance across RPM ranges. The separation spacing ensures consistent, stick-free operation even in high-humidity field conditions where moisture accumulation would otherwise compromise responsiveness.

This call performs best for hunters pursuing spring or fall turkeys in open or semi-wooded terrain where vocal range flexibility is critical. The Primos Deadly Double excels when switching between calling strategies—transitioning from soft locator yelps to aggressive fighting purrs without equipment changes. Weighing just 0.25 lbs, the call is packaged for maximum portability, fitting easily into vest pockets or call bags alongside other hunting gear. The design works equally well for box-call users learning diaphragm techniques and experienced callers refining their advanced vocalizations, making it an effective tool for skill progression throughout a hunting career.
