First off, welcome to Radioreference, you made a very wise choice to join this group. To familurize yourself with scanning in general & as which brand & model would work best for you, check the WIKI section on scanner types & other topics that may assist you in making an informed decision. Also check the RR database for Michigan to find out the types of communications frequencies & systems in use. I'm sure you will be getting additional replies as time progresses. Good luck & again, welcome, always feel free to ask any questions you may have.
