passthrough24- I just purchased a Primos DVD with a Howler call. The movie is called "The Truth II- Callin' All Coyotes"... about 3hrs long.
The narrator/hunter/instructor is Randy Anderson. His comments and how to's are very good.
I always used a cottontail distress call and a fawn distress call. Never knew how to howl, etc. This DVD will not only show you some great shots on coyotes, but you'll learn how to call with some different mouth calls.
Hope this helps you.
