The Haydels Game Calls Black Hole is a high-volume double-reed duck call crafted from durable black polycarbonate. Originally created as a 25th Anniversary edition, it features a specialized Black Hole exhaust port designed to produce extra-deep, raspy mallard tones. The double-reed system provides a non-stick and user-friendly experience, making it difficult to over-blow even in cold or wet conditions. This open call excels in timber or small marshes, offering stable performance for low-end feeding chatter and subtle quacks. It is an ideal choice for both beginners and experienced timber hunters. Safety Note Waterfowl calls can attract other hunters to your location; always maintain situational awareness and inspect the double-reed set and internal O-ring regularly to ensure components remain secure.
