Congrats on getting your new scanner, and welcome to Radio Reference!
One thing to understand is the Pro-2018 is a basic scanner, and one of the things that it does NOT do is trunking - a form of radio communication that is becoming more and more popular everyday. Visit
this section for an introduction to trunking. Since you specifically mentioned Michigan State Police, they're using a digital trunked radio system - something that only a handful of scanners will listen to. The scanners that will do
digital trunked start at $400 (new) but can sometimes be found a little cheaper in the used market.
Furthermore, the scanner will not allow you to program in any frequency higher than 512MHz, so if you see something you want to listen to that's higher than that, you're out of luck.
If you have questions about specific systems or localities near you, you might find it easier to post a message in the Michigan section here on Radio Reference. If you have questions about programming the scanner itself, and it can't be answered by the owners manual, let us know...we should be able to provide some assistance.
Good luck!
