Radar guns feature both a radio transmitter and receiver. A radar gun uses radio waves to detect and monitor moving objects.
Do radar guns need calibrated?
Radar guns need frequent calibration with tuning forks to ensure that they provide correct readings. Manufacturers of these devices recommend that users calibrate their machines prior to each use. However, most police departments don't require this, which means that the readings may not be as accurate as believed.
