I'm not exactly sure how much just a hunting license costs. I get a combo license and it costs $40.
As far a calls go, it's really a personal preference. Electronic calls have come a long way the last few years and you can get a good one for around $150. The pros of an electronic are you can set it away from you so that the coyote keys in on it rather than on you. Me, I like hand calls. They are pretty cheap and with some practice are easy to use. I learned on a closed reed mouth call. They are generally a little easier to learn to use. With that said, I use mostly open reed calls now because I like the way they sound and they can be manipulated on how high or low you want the pitch of the call to be. Either way be careful. Calling coyotes can become an addiction.
