It's actually very simple in theory.Just like your eyes detect variations in the way light hits other objects the radar detects variations in microwave (and other types) of radiation.The trick is in figuring out exactly what this means through signal processing.
Only if he has his radar gun on. Radar detectors are not cop detectors.
Radar detectors are legal. Radar scramblers however are NOT legal.
A cobra detector is a radar detector. Radar detectors work the same way a radio receiver does. The radar detector looks for frequencies that a radar gun uses.
The best radar detectors on the market are made by Beltronics. Beltronics is a leading manufacturer of the Vector, Professional, and Express radar and laser detectors.
Laser detectors detect laser beams used by law enforcement to measure speed, while radar detectors detect radio waves used by police radar guns. Laser detectors are more precise but have a shorter range compared to radar detectors. It's recommended to have both types of detectors for comprehensive coverage.
Radar detectors are legal to use for all non-commercial vehicles in 49 states. Washington, DC and Virginia are the only two states that radar detectors are banned in the United States. Radar detectors used in commercial vehicles are illegal.

Radar detectors are legal to use in Nevada, but as you stated they are illegal to sell.
Yes, but not as well as we wish they would work! Don't depend 100% on a radar detector. There are a number of related questions and answers on WikiAnswers on radar and speed control. A link is provided.
Cobra radar detectors are devices used to detect if the police are monitoring your car or checking your speed limit using a radar gun. This is used by motorist so they can fix their speed before getting pulled over.
Valentine radar detectors are the most popular for their sounds.
Radar detectors are legal for passenger vehicles in North Carolina. However, they are prohibited for use in commercial vehicles. It is important to note that while radar detectors are legal, the use of radar jammers is illegal in North Carolina and throughout the United States. Radar detectors are devices that can detect radar signals emitted by police radar guns, while radar jammers are devices designed to interfere with or block radar signals.
