I have the Primos Power Crow to and love it. You can make all kinds of calls with it. Bite down on it and you can make a coyote howl and if you practice enough you can do turkey yelps,cutting,peac@ck screams and pileated woodpecker calls. When you bite down on it blow in it and let off a little pressure. Just play around with it and you will see what I mean. The coyote howl sounds pretty good when done right.
