I've read alot of comments about the X50 and other detectors not picking up laser unless it's scatter or a direct hit within a narrow range. Well, here's what happened to me Saturday:
Traveling WB on 820 through Saginaw at 70 MPH, I'm in the center lane starting to overtake a SWB maintenance van blocking the left lane. As we both top an overpass, I see a police Camaro in the center median just past the crest. Now, keep in mind at 70 this all happens very fast. As we approach, I see the LEO turn around at the back of the car and raise his laser gun, pointing it at oncoming traffic. By the time his arm is level and the gun is pointing down range, I am at a 45 degree angle with him and have slowed so that I am using the van as a shield. In the instant before the van completely blocks him from me, I can plainly see that he is in fact pointing the gun at oncoming traffic behind me. Laser alert goes off on the X50 as I pass him, 90 degrees to me.
So, what happened and how did I pickup laser? At such an off angle I should not have picked it up. It may be possible that when he raised the gun, he triggered it and the beam sort of swept up and scattered as he aimed it at oncoming traffic, allowing me to pick it up. I don't remember seeing that happen, but it all happened so fast it's quite possible I didn't see it.
