The Haydel's Game Calls Big Blue is a specialized double-reed call engineered for maximum volume situations. Crafted from dense, clear acrylic, this call delivers the superior resonance and sharp, crisp notes necessary for large marshes and open wetlands. It features double mylar reeds designed for a rapid-fire response, allowing hunters to easily mimic the fast, high-pitched piping quacks of Blue-winged Teal. Equipped with a double O-ring seal to ensure an airtight fit and consistent air pressure, this open call is a rugged and user-friendly tool specifically tuned to hit the distinct vocalizations that define excited teal. Safety Note Due to the high-pitched nature of teal vocalizations, avoid blowing the call at maximum volume in enclosed blinds to prevent ear fatigue; rinse the double reeds regularly with lukewarm water to prevent sticking.
