The Cobra XRS 9930 model is particularly advanced because it can pick up on any radar signals that are currently in use. This means that the latest models of police speed detectors can be tracked by the device, including the electronic boxes that are sometimes put on the highway to help drivers monitor their speeds. 360 degree protection from all types of laser guns is also a part of the product features, which means that you will be notified when a police officer is behind you, miles in front of you, or on either side of you on the highway.
