The high-performance Adrenaline goose call features the Mark II Semi-Worm Gut System. It combines realism with serious control for advanced note combinations. The Adrenaline is one of the loudest goose calls on the market with the widest range of sounds available. It has been used to capture many goose calling championships including three 1st Place World Goose Calling Titles. The Adrenaline is the perfect call when you need the most volume possible to call distant flocks of migrators and finish them in the decoys with rich full honks and moans. Every Adrenaline is hand tuned by 2-Time World Goose Calling Champion and 2-Time International Goose Calling Champion Field Hudnall.
