The Uniden BearTracker 885 Hybrid CB Radio/Digital Scanner can keep you up-to-date with current public safety activity in select locations by scanning for police, fire, ambulance and/or DOT radio traffic. The included GPS allows the BearTracker 885 to automatically select nearby channels from its nationwide database without you having to lift a finger. BearTracker Warning System alerts you whenever there is nearby public safety radio traffic by checking the low-power signal produced by the radio in the public safety vehicle.
