you buy an expensive one
Very accurate, it measures speed and doesn't care if the vehicle is traveling up or down, toward or away from the radar gun.
idon't know about the speedometer reading but the speed the radar gun is the same as the relative movement of the vehicle not the speed at which the tires revolve
with a radar gun
i dont think it can because it take a reading like a photograph it doesnt carry on changing the speed. For example: when you take a picture it takes a snapshot of what it can see. The same is done by a radar gun. Hope this helps!! :)
This a section for FIREARMS.
No, not on the scene. But if you go to court the officer will have to present certification as to their training to operate it, and the fact that was"calibrated."
No, if you are moving 30 mph and another car is too, the radar would say the car is going 0 mph. depends on where you are... in some areas yes Thats the idea, radar guns are used to check a vehicles speed, if you mean can a radar gun be used from a moving vehicle then no, the gun must be stationary otherwise an inaccurate reading will result.
It measures the time it takes for the radar pulse to go from the radar gun to your vehicle and back. The pulse is fairly constant so the radar gun is getting updates and by comparing the updates to the time it can determine speed.
A radar gun only works when there's a free line-of-sight betweent he gun and its target vehicle.
A radar gun can detect the speed of vehicles of up to 1 mile, on an average. It depends on the radar gun's make and model, it may detect farther than 1 mile.
Not sure, but I would think it would be the same in all states. In Louisiana, if you get stopped for speeding, you have the legal right to request to see the radar reading. And to note the time on the gun that the reading was made. If you feel it is not correct, and that you were not going as fast as the officer claims you were, you also have the right to request to see the calibration record of the radar equipment. The radar equipment is supposed to be calibrated at least once a year, and if they cannot, or won't show you the calibration record when you request it, then you should have a pretty good case to fight the ticket in court.
Yes. The glass does not affect the radar.
