I'm thinking about hunting some coyotes at night with an electronic caller and my 22-250. My question is, how do you find the yotes at night to shoot them. I plan on taking my spotlight out with me (obviously), but how do you know when to turn it on and look for them? Do you periodically scan until you see them? Wait until you hear a sound? What is the best way to go about it?

Also, does anyone have suggestions for a cheap electronic caller?
