I'm pretty new to the Coyote Calling world. I do not have any custom calls.
I haven't killed dozens of yotes, either. How ever I have had allot of encouters, and interactions with them. Using calls I've bought from Bi-Mart,Wal-mart, Sportsmans warehouse, & Cabala's.
I think most of it is learning how, and when to use the sounds. Primo's Catnip is one of my favorites, as well as there Lil' dog howler. Other than that I use my turkey diaphragms. Keep mixing it up. Depending on what stand I'm on, and what I used the last time I was there.
