ABSTRACT:
An improved call for use in calling waterfowl or game in which the call has a unique set of interchangeable chokes so that the volume of the call can be easily varied by the user. The precisely designed chokes provide the user the ability of changing the volume by replacing the choke so as to better fit the particular conditions of the environment without changing the reed size or thickness. The call also contains an opening in the side of the barrel which opening is normally closed by a plug which can be removed to allow the user to simulate different calls.
