Police Radar
Information Center

A detailed description of police microwave and laser radar, also called lidar. Radars and lidars are not just point at target and click (transmit) devices. There are some basic setup limitations and operating procedures that must be observed. Too often procedures are not properly followed in order to save a little time or hide from motorists, resulting in speed errors. Additionally, far too many operators don't remember, or don't use, any of their radar training.

Inside a Sports Radar

Police radars and lidars are not just point (at target) and click (transmit) devices. There are some basic setup limitations and operating procedures that must be observed. Too often procedures are not properly followed in order to save a little time or hide from motorists, resulting in speed errors. Additionally, far too many operators don't remember, or don't use, what they were taught in radar training.
