The ultimate full range duck calling machine. The short mouth piece allows deep low end quacks and soft hen cadences, while easily transitioning to young high pitched excited hens. Its versatility of multiple pitched hens is an innovation that double reed callers are going to love. The chatter is sharp, crisp, and has the control of a single reed. The most impressive aspect is its volume control. Whisper the softest quacks and cadences for timber hunting and no wind days and then as quick as a deep inhale you can lay into it to get volume and power. Hand tuned and tested.
