Made from 100% polycarbonate to offer years of durability and great sound! These inserts easily produce soft quacks, feed calls, come-back calls, and of course the infamous hail calls. The unique insert allows the call to ring on the top and also allows for low-end tones making it an excellent choice for any beginner or experienced caller.
All Slammer Series inserts come assembled and pre-tuned with high quality mylar reeds, a rubberized cork wedge, with a long lasting o-ring.
