Coyote/Bear mouth calls?

[tides56]

I have tried my luck at coyote's numerous times with some cheap electronic call. I know upgrading to a better one won't all the sudden make them come running. Do you prefer mouth or electronic? Can you please recommend some? Thanks hope all is well!

Gutpile and I both have Foxpros, he calls in lots of yotes with, but I never have. I've called all of mine in by mouth. A lot of them using bearmanricks calls. He is a sponser of this site. Look in the coyote hunting section.

I have used the Primos coyote/bear buster with success. It is a fawn in distress call. It works well for mule deer does also.
