I especially like thpse calls on big windy days. I like them for long distance shock gobbling.
That is one awesome gift. You can do the same thing/make an instant wingbone call in a pinch with a ball point pen barrel if you take the pen apart.

I have seen some made of wood that looks like a ball point pen..
The guy that made mine has a few short videos where you can see and hear the hens talking back at him.. He is super with those calls..
