After many years of driving without one I finally broke down and bought a radar detector. An Escort 8500 to be exact. I noticed that in the city, even when a cop is sitting there with his radar always on, I don't get an alarm until I'm well within visual range. For POP I'd expect this but even in Constant-On mode I've never seen a range more than 100 yards or so. This doesn't make sense. This is a good detector. Is it just me or does every detector suffer such short ranges in the city?
