Talked to an officer at the county fair....started off talking about cars then engines,,,then we started talking about radar. He said they use MPH Python Radar (which I knew) and he also said he has a switch that you can push to operate the Front radar or rear radar (kinda like a toggle switch) and then too told me about how his python can track from a mile away. Told me about instant on and he said the only way a radar detector can catch the radar is if there is a car half a mile ahead the the detector. I didn't let him know that I had a detector though. Then they said they dont use laser at all :P Kinda cool getting to talk to him...nice officer he was. Then he said .....the biggest thing was that when he uses moving radar he said that when shooting someone with instant on the officer has to be moving faster than the target ...otherwise it gets a weird reading.
