Sorry, the kind of detector you have is irrelevant when they pulse you. A radar / laser detector can't detect one that isn't on!
That is why you are supposed to have a rabbit that is a good distance in front of you so that they get pulsed and you detect it and have time to slow down. The kind of detector you have is relevant because crappy detectors have crappy range and they won't alert to quick trigger pulls of the radar gun.
