No more need to flutter your tongue. Change your tones and sounds by using the slide tuner or side vents. A great call for whistling waterfowl like pintail, teal and wigeon.
Maybe if you start out with this call it will work fine for you, but having used the original Wing Setter for many years I was disappointed. Thought I would give it a try as I tend to bite the ends off the original, I use them a lot. But just can't get the volume or same good sounds. Probably just an old dog that can't learn new tricks. I will stick with the original. They are deadly on Green Wings and Widgeon.
