When Wayne Carlton brought diaphragm calling to elk hunting, he had three things in mind: Reliable, realistic, and hands-free. This single-reed call is far and away the easiest diaphragm elk call to master, and an ideal resource for realistic hands-free calling.The Single Reed Red consistently produces realistic cow/calf and young bull sounds. It blows with the least amount of air and is a great beginner call. Featuring durable Infinity Latex, it absorbs significantly less moisture for long-lasting performance. If youre going to use diaphragms to call elk, use the ones designed by the man who revolutionized the art of calling elk.
