Trying to estimate warning time in an actual mile or feet measurement is impossible since true warning time is influenced by many outside variables that have nothing to do with the radar detector itself.

Sensitivity refers to a radar detector’s ability to pick up police signals at the greatest distance. Selectivity refers to the detector’s ability to filter signals that are not true police signals, yet operate on the same frequencies as police radar.

Speed signs – or speed reading boxes – are radar-based. Radar detectors are not radar jammers. Jamming radar is a federal offense and is prohibited by federal law nationwide.

If a police car is not equipped with a radar or laser gun, a radar detector cannot possibly locate it. Also, if no signal is transmitted when you pass the police car, there won’t be any signals for your detector to receive.

This is a very short transmission signal that allows the user of a radar gun to capture a quick read of a vehicle’s speed prior to setting the gun to another band.

No, we do not. The sale and use of radar jammers has been banned by the Federal Communications Commission (FCC) since 1997. The fines for each violation can reach up to $11,000.

Putting tint of any kind on your windshield that contains metal film is essentially like putting a blanket over your radar detector. While radar microwave signals can still travel through fiberglass, plastic, and glass, they cannot penetrate metal.
