The Haydel's Game Calls MP90 Magnum Whistle is a versatile, high-volume multi-species tool crafted from high-impact black plastic. As part of the Magnum series, it is engineered with a larger design to provide increased volume and projection, making it highly effective for cutting through wind in open-water environments. This whistle is uniquely capable of reproducing the distinct vocalizations of Mallard drakes, Pintails, Widgeon, and Green-winged Teal. With its simple operation and beginner-friendly difficulty level, it serves as an excellent confidence call to reassure wary ducks and is a perfect way to involve younger hunters in the field. Safety Note Due to its high-decibel Magnum design, avoid blowing this whistle at full volume in enclosed spaces like boat blinds. Regularly rinse the unit with warm water to remove saliva and debris, ensuring a clean airway for accurate pitch.
