I recently learned that I am lacking certain sounds in my calls. I have no way to reproduce coyote vocalizations. I was hoping you guys could help me out with some ideas. What would be some good mouth calls to get? I looked at Bass Pro and Cabelas but, I can't tell one from the next. I would like to buy as few calls as possible{ofcourse}. What would be a good call that can make a bunch of sounds? Or a good comination of calls would be helpful. Thanks in advance for the help.
