ABSTRACT:
The present invention provides a dual diaphragm-type game caller of a size and shape suitable for inserting into a user's mouth for support against the roof of the mouth so that free edges of two diaphragms retained together as a unit in a spaced-apart relationship can concurrently vibrate when impinged by pulmonary air exhausted by the user. The invention employs two diaphragms having a selected pattern of slits which allow the caller to produce a flutter or raspy sound effect which is sometimes desired by the wild turkey hunter. The present invention also provides a removable spacer of a size and shape suitable for insertion between the two diaphragms when the caller is not in use, such that the two diaphragms are kept completely separated, thereby preventing one from adhering to the other.
