oh, now that is a good question.. I have killed Three coyotes with my Boom Box and they were totally a woops.... I called and then drove around the block and ended up shooting one on the other side of the block I was previously calling, he was heading toward where I was but takeing his time.. so would it work????

You will get a lot of comments saying try it and it will tell you if it will work.. For 200 dollars you can pick up a good caller.. and its worth picking one up if you are planning to get into it hott and heavy..
Other wise get a couple videos teaching calling methods ans watch them practice them and you will soon be killing with the best of them. picking up these videos is cheaper than a new caller with the same effects.
