Abstract
The present invention utilizes a sized coil spring placed in the end of game call tubes, or mouthpieces that go into such tubes. When air is blown into the tube or mouthpiece, the air passes over and through the coil spring, causing the spring to vibrate and make a whirlwind effect. The vibrating coil spring increases the volume of the sound and also stabilizes each tone created on the mouthpiece or tube. The higher tones, or notes, are more easily obtained and become easier to reach and hold with consistency. The coil spring also helps to increase back pressure, making it easier to blow into call with less air to make the call work. This invention can be used in all types of game calls, such as calls for elk, deer, moose, wolves, predators, geese, ducks, and even some turkey calls. The invention makes the desired sounds more realistic and user friendly.
