Doesnt detect cops
Radar detection is not an absolute...there are several factors to consider:
-Most radar guns have an adjustable "gain"...which means that if an officer is only checking speeds to vehicles close by, he or she has the option of turning down the power. This means that your detector may not pick up the radar until you are right on top of it, if at all.
-Many police agencies are using laser or LIDAR technology for speed detection. Even if your detector is able to detect laser, the detector will not "see" it unless the police officer aims directly at your detector. The laser beam is very precise, and is only the size of a penny on the target vehicle when the officer is 1000+ yards away. Since the officer is usually targeting your license plate (it is the most reflective, and therefore the best target), the detector on your dashboard may miss it.
-Many radar guns, whether handheld or vehicle based, have an instant on feature. If you are in a "radar detector friendly state", the officers in your area probably use this option so they don't give away their location to those with detectors.
If in doubt, you may want to check your detector in the same vehicle with someone who has a known working one. If their detector goes off, and yours does not, yours is likely defective.
