so i picked up a passport to run for fun, and i have to say i'm quite impressed with the range of this thing. Got it for 149 bucks refurb from escort and its the not the x50. Ran into about 5 cops tonight and they all run 35.5 or 35.4 around my house. I picked up one on a straight road heavy populated with buildings about 2 miles from when i hit the od, but he was traveling 50 mph at me also. Then there was two 35.5 by my house and picked it up well before i seen them and they were hidden in between buildings. But just didn't think I'd see this kind of performance.
