This cow talk call can stop a wounded bull elk giving you that 2nd and 3rd chance to shoot again. If you are hunting elk without the original cow talk call, you are handicapping yourself. This is a year around call for calling in bulls as well as cows. One end of the call can be tuned for calf sounds and the other for adult elk. This call fits in your pocket and is not necessary to use with a grunt tube. This is not a diaphragm call and is easy to adjust.
