Was talking to a local city LEO today about the radar guns they use. He told me that they don't use Laser but they use Ka radar guns. I ask him if they were using Pop Radar and he had no idea what I was talking about. Then he went on to tell me that their radar guns work like this. He said that as soon as he points and turns it on he gets an instant speed reading. He saids it has two buttons: one that turns it on and keeps it on constantly and the other button turns it on and off to get a instant speed reading of oncoming target. Could this be a radar gun that has the POP radar or is this just the way Ka radar guns work and POP radar works dfferently? Anyone know the answer?
