I am one of the lucky few that bought my passport off EBay and have it actually work, that was before I found this site. Today, I had my first experience with Ka and Laser...from the same cop. I left home and picked up a weak Ka where I never had a false before slowed down and around 2000 ft over a hill, there he was. Normally, people travel 40 here and the limit is 25. Anyway, on my way back I was going 25, but didnt pick up any Ka. I stayed at 25 just in case and then got my first LASER alert. My passport is mounted about an inch below the rear-view mirror and it still picked up the Laser at inside of 1000 ft, probably around 600 ft. I wonder if he was aiming at the windshield, because I find it hard to believe that I would get an alert at such a close distance aiming at the headlights or license. I wonder if my car being silver reflected the laser and added to the detection range (Jim, do you know if this happens?). The cop was parked perpendicular to the road and shooting outside his window. Even though it didnt offer me any warning had I been going 40, I think this is a pretty good case of a passport being very capable at alerting to LASER.
