As far as I know there is only one company that make a POP radar gun. M.P.H., anyway, it turns the radar diode on and off in a short burst, .67 milliseconds. Two things. 1. It turns on and off so fast that most detectors can't pick it up. 2. I have read the manual and this is the funny thing, it says not to write tickets based on this reading but rather to put the Radar unit in a on mode to measure the speed over a distnace. POP only tells the user the speed of the fastest car in a general area and as of yet I have seen no tickets written on this information alone.
Maybe one of the officer on the forum can tell us more??? Not sure why they couldn't just write the ticket based on the POP.
KJ, I turn POP mode off in the Cincy area, no one in OHIO that I know off has POP, could be wrong though. The thing of it is, a detector has to “sweep” very fast to catch POP and therefore has less time to weed out false signals thus falsing more often. Just because your detector goes off, doesn’t mean that someone is using POP in the area. BTW. sweep is the rate at which a detector scans all the frequencies that radar units are transmitting. Kind of like a scanner for police and fire signals.
As for laser falsing, I see a lot of it around airport runways, not sure what the source is but very common. The frequency of a laser gun is in the Infared range, so there are some things that can set it off. I have seen old red neon lights set off laser alert. Also, if the unit is dropped a lot it would start falsing more often.
