    Default What an officer had to say...

    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.

    I never heard of that one, The moving radars know wich speed the cruiser is travelling and it calculates the speed gap between the two, to give a reading. No matter how fast the LEO is travelling , he is supposed to get a good reading.

    Maybe that officer needs a training refresher course of some kind. My buddy is a State Trooper and they use the exact same setup as the officer that you spoke with, and I have rode with him while he was off duty and have clocked people myself going in the opposite direction that was traveling at a higher speed than the cruiser and have received accurate readings everytime I blasted an oncoming car. One chick in a Ford Focus was doing 51 in the 30 zone we were traveling. The funny thing is he knew it before i even flipped the switch; his exact words were this ***** here is flying.

    With some older models of radar guns, the operator had to tell the unit whether the patrol car was going faster or slower than the vehicle being targeted. With newer units, this is done automatically now.

    When clocking a vehicle going in the opposite direction, the relative speed between the patrol car and the suspect's vehicle is first calculated. To get the absolute speed of the vehicle, the patrol car's speed is subtracted from this number.

    When clocking a vehicle going in the same direction, again the relative speed between the patrol car and the suspect's vehicle is calculated again. Depending on which is traveling faster, the relative speed will need to be subtracted (officer going faster) or added (suspect going faster) to the patrol car's speed to get the speed of the suspect's vehicle. If an older unit is in the wrong mode, the relative speed will be added instead of subtracted or vice versa. If the officer is going faster, the suspect's speed will be higher than it should. :cry: If the suspect is going faster, the suspect's speed will be lower than it should be.

    He was a youger guy and said how he still has a little trouble though with radar especially if you are far away from a target vehicle.
    He said state troopers could do it all day long and could look at cars and tell pretty well how fast they were going.

    Yeah, if it's a turkck or SUV. For an average mid-sized car it's more like 1500 ft. For a 'Vette (non metallic paint) or TA (Ram Air hood and non metallic paint) it's a little over 500 ft. Target range can vary a lot among vehicles.

    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.
    That depends on how good your radar detector is and the terrain. On a straight road with slight hills, it could be more like 2 miles if you have a top-of-the-line BEL, Escort, or V1. If you have a Cobra or Uniden, it will be more like a half-mile, if that much.

    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.
    Maybe his radar has a defect. Or possibly he was referring to the use of same-lane mode. With some radars when same lane mode is used, you have to select whether the patrol car is moving faster or slower than the target.

    If there is a mix of like 5-6 cars..several in front and back..and they are about ~ 1/2 mile away, and the officer uses his radar, can he 'choose' a vehicle to target...or can the radar 'pick out' somehow the fastest of the bunch...its confusing to me
    i know with laser you can select a car like that..but i thought with radar you kind of just select a car that's kind of by itself to target when further away

    The newer radars will pick up the fastest car of the bunch but they cant pinpoint a specific car. So it all goes to the LEOs choice, they often choose the fastest looking car of the bunch.

    I got pulled over once. I was with 6 cars, we were all speeding on interstate 30 in arlington,tx.
    When i asked the officer why he chose me out of the bunch he said
    "your car was the best looking one "
    there ya go.
