Abstract: An adjustable game call device is provided. The bell has an inlet end and an outlet end to define a channel for the continuous passage of a column of air therethrough, the bell having an expanding cross-sectional area along at least a portion of the channel. The adjustable game call device has an adjustable caller assembly that includes a barrier member disposed within the bell and an adjustment member attached to the barrier member. The barrier member is movable in an axial direction within the bell by actuating the adjustment member to vary a distance of the barrier member from the bell inlet between two predetermined positions. Varying the distance of the barrier member from the bell inlet modifies the column of air traveling through the channel to change a characteristic of an animal sound created when the adjustable game call device is in use.
