The Haydel's Game Calls Blue Wing is a high-performance open call precision-tuned to replicate the distinct vocalizations of Blue-winged and Cinnamon Teal. Crafted from vibrant blue acrylic, this call provides a sharp, piercing resonance that perfectly mimics the rapid-fire, screechy quacks of these small ducks. Unlike green-winged teal calls that whistle, the BT85 utilizes a highly responsive single-reed system to achieve the high-pitched peep and erratic calling sequences typical of hen teal. With a double O-ring design for an airtight seal and a compact barrel for superior frequency control, this durable acrylic call is an essential tool for early-season waterfowl hunters. Safety Note Due to its high-pitched and resonant nature, avoid blowing the call at maximum volume in enclosed hunting blinds to protect your hearing; rinse the unit regularly with lukewarm water to prevent debris from affecting the single-reed vibration.
