The Buck Gardner Spit Tech Double Nasty Mallard Acrylic Duck Call is off the charts and is rewriting the book on duck hunting. This totally new design is absolutely guaranteed to blow even when full of spit on the coldest days. The all new tone board will do everything from the highest ringing hail calls (Can you believe that from a double reed!!) to the lowest clucks and whines. Feed calls free and easy and has that extra raspy bottom end and midrange that the Double Nasty is so famous for. We recommend you “Wet-Tune” or wet the reeds and cork before blowing, as it blows better full of spit. SPIT TECH, it's what you've been looking for.
