Tree 44s has pretty much nailed it. What he gave you is good advice. Don't expect great results right away (unless you happen to be in a really coyote rich environment that is not called much) and remember the basics of wind, movement and marksmanship. They are sly, smart critters with a good memory. They will rarely make the same mistake twice. Read as much as you can about coyote hunting and always be ready for the unexpected because that is when they'll come. Good luck and keep at it.
