Only three states, Oregon, Iowa, and Nevada have issued state purchase orders specifying MPH two piece Ka radar guns with POP Mode.  MPH’s new Ranger EZ does not offer POP Mode. Your chances of encountering POP Mode are the same as you traveling to the moon on a bungee cord.


According to the Operator’s Manual, POP Mode may not be used to issue speeding tickets as it does not provide a tracking history of the target vehicle. It can only be used in the stationary mode. It assumes, officers know a radar detector is in operation in a group of oncoming vehicles. They don’t! Honestly, the POP feature was used to “spec” out  other competitors in the radar gun procurement process. It does serve a purpose on the front page of the local paper when police say they have a radar gun detectors can’t see.  This was true with older detectors, but not now! POP Mode transmits a short, 67 ms, (thousandths of a second) 33.8 GHz transmission. POP Mode is offered in K and Ka bands by the manufacturer.


Vehicles with detectors were located at a cone 1,000 feet from the POP radar gun. They drove toward the gun at 30 mph.  They were POPed as they approached. A speed was visible in the target window of the radar gun verifying a speed reading. Only twice in all of the runs of all the competitors did the detector not report POP mode nor report a Ka radar transmission. To reverify we had one Cobra and one Whistler detector run the course again.  This time all saw and reported the POP mode. On the first run with the Valentine One (serial number# 6185651003) it did not detect POP mode. The reason. We forgot to turn it on. We are not perfect! When operational, it detected POP each time.  Detector makers put POP Mode detection and reporting on their packaging. They must to be competitive with their competition.  Their packaging is correct!


Why should you worry about POP?  Radar detectors in
cars are legal in all states except Virginia, Washington, D.C. and U.S. Military Installations. In Canada, radar detectors are only legal in British Columbia, Alberta, and Saskatchewan. February 1995 saw U.S. DOT ban radar detectors in commercial vehicles, i.e. 18 wheelers in all states.  Increasingly, SafetyRadar© uses radar detectors to slow drivers down with radar drones in work zones, school zones, school busses, ambulances, and neighborhood associations. Radar drones transmit police K or Ka bands. Detectors now identify the band received. South Carolina just bought 300 drones.  If you receive a K or Ka band notification, it could be the cops or it could be a radar drone. You don’t know. Better slow down! The detector makers have figured out POP mode and use it to their marketing advantage.
