Effectiveness of Radar Detectors

A Radar Detector is an effective and proven way to protect you from a speeding ticket. There are 3 main frequency areas that police radar works in, generically known as X band (11 GHz), K band (24 GHz) and Ka band (32- 36 GHz). All a radar detector does is listening to those frequencies and beep, chirp and flash when it receives a signal. The more sensitive it is, the earlier it will warn you. About the effectiveness of radar detectors, Yes they are really effective. Radar and laser detectors are sophisticated receivers designed to detect the presence of radar and laser energy at great range.

Radar detectors, like the flashlight example, can receive the signal well before the transmitted signal can bounce off its object and return to the transmitter. (One exception to this is if the officer is using a method called "instant on." In this case, the officer waits until a vehicle is within its range, and then turns on the transmitter. Under this scenario, a good detector will warn you ahead of time since it is sensitive enough to detect this burst of signal when the officer targets the vehicles in front of you).
