The RS Pro-91 is one of my older, but reliable, police scanners. It is capable of trunking and can store 150 channels. Overall, this is one tough scanner; even though I have dropped it many times, gotten it soaking wet, and left it in my car with the outside temperature being over 100 degrees Fahrenheit, it has always worked perfectly (except it sometimes says "low battery" when the batter is not actually low). The Pro-91 is, ". . . designed to track Motorola Type I and Type II (such as Smartnet and Privacy Plus) and hybrid analog trunking systems, which are extensively used in many 800 MHz communication systems" (Pro-91 Manual). It has 5 storage banks that hold 30 frequencies each. It also has a backlight that stays on for about 15 seconds at a time. I think when I got this a few years ago, it cost $150.

The book shown at the end is the 10th edition of Northwest Frequency Directory (NWFD) edited by Dan Rollman and published by Scannerstuff LLC. This book has frequencies for all over the United States, not just the northwest. Not only does it have public safety channels and talkgroups for police, fire, and medical; it also has business frequencies, airplane frequencies, federal government frequencies, amateur radio frequencies, radio codes, terms, maps, background information, and more. I highly recommend it for people who want to be or are radio monitors. For more info on this book, go to http://scannerstuff.com/
