1. Always use the wind to your advantage. Either set up with the wind in your face or set up with a cross wind. That way they can't smell you.
2. If you don't care about saving the fur , use your favorite deer gun to hunt them. The more shooting you do with it the more familar you become with it.
3. Actually find Randy Anderson's first video (Calling All Coyotes) and watch it a few times. It offers tons of coyote hunting tips and is also a good watch too.
4. Don't give up. If you go out calling and don't call anything in, don't worry about it. Keep trying. They might not be in the area or whatever. Persistance pays off.
There's alot more tips I can give , it's just that I can't think of them right now.
