I have had a Bear Tracker for years...never use it. As a scanner, the sound quality isn't very good, and it is hard to discern what is being said. It works by picking up "repeater" signals, that many police vehicles emit when the mic is clicked on. (It involves switching between frequencies) If a police officer is not talking on his radio...there is nothing to detect.
Remember that this is not a radar detector.
