We’re not kidding when we say this is the mother of all duck whistles. Slayer Calls partnered with one of the top whistle engineers in the country to learn what makes whistles work and how to make them insanely loud. The collaboration led to Whistler’s Mother, a 4-in-1 duck whistle that blows other whistles out of the water. Whistler’s Mother fixes the two biggest issues with duck whistles that we’ve found in our decades of waterfowling: They’re too quiet, and they’re too complicated. Slayer’s duck whistle is designed to maximize volume without losing its realistic duck sounds. There’s no need to worry that the teals can’t hear you 50 yards away — this mother can bring in the high-flying birds. There’s no need to break out an owner’s manual to figure out which magic combination of words, air and hand placement will unlock the different vocalizations. The Whistler’s Mother has a right and a left hole which each produce two duck sounds by simply blowing the whistle. Beginners can easily pick up this whistle and blow to achieve calls that can help them kill more ducks.
