I was driving in East Idaho yesterday along US-26 when out of nowhere an Idaho State Police showed up driving along the other lane. My Passport 8500 x50 didn't alert me until he was only like 200 feet from me (there were no lights on top of his car, so I couldn't tell it was an office until I saw the decal on the side of the car). Im pretty sure he used instant-on. He got me going 81 in a 65 but wrote it for 79 to avoid excessive speeding.
Thinking about selling my passport. Even though I should have been a little more careful, I just dont see the use for having a detector anymore!
