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.
with a radar gun
To measure the speed of a slapshot in hockey, a radar gun is commonly used. The radar gun emits a signal that bounces off the puck and calculates its speed based on the return signal. This provides an accurate measurement of the speed of the slapshot.
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.
If you put larger diameter tires on your car, the speedometer reading would be slower than the speed measured by a radar gun. This is because larger diameter tires cover more ground per revolution compared to smaller tires, so the speedometer would underreport the actual speed of the vehicle.
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.
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.
Only if he has his radar gun on. Radar detectors are not cop detectors.
