![]() AntennasĪ radar detector’s antennas are like its “ears.” They allow the detector to search for radar and lasers in many different directions. Given that, many companies avoid telling you a detector’s range and lean on non-specific terms like “long range.” That said, we’ve tested the radar detectors on this to get a sense of their relative ranges and accuracy. Some detectors only track 100 feet away, where others can sense many miles away.Īt the same time, it’s important to keep in mind that a detector’s effective range varies at any given moment, based on dense objects that could cause interference and even weather. That means your radar detector’s range effectively determines how useful it can be. If you’re looking to avoid a ticket, you need a radar detector that will notify you of an upcoming checkpoint far enough in advance for you to slow down if you’re speeding. Unlike radar that can usually be detected in advance, police point lasers at a specific vehicle, so drivers don’t get advance warning. Police laser guns emit short bursts of infrared light that reflect off a vehicle and return to the device. Ka band has a narrower beam pattern and lower power output than both X and K band, making it the most difficult type of radar to detect at long distances. Its successor, K band, operates on a higher frequency and has lower power output, making it harder to more difficult to detect at long distance. X band is the oldest form of radar used by law enforcement and is now uncommon. In the US, law enforcement typically uses one of three radar and laser types–the X-, K-, and Ka-bands. Using one feels like using an AM/FM radio: The receiver in the detector tunes into active radar signals, just like a radio tunes in to active radio station frequencies. Radar detectors allow you to find radar and laser signals used by law enforcement to measure vehicle speed. What to Consider When Buying a Radar Detector How Radar Detectors Work Highway patrol and police frequently use radar-detector detectors to sniff them out, so using a detector in a state where it’s illegal may actually increase your chances of getting pulled over. The details of the laws vary from state to state, including the penalties for breaking them, but we would strongly recommend turning your detector off and putting it away while driving through states where they are banned. They’re also banned in most Canadian provinces, including Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland. In the US, drivers are not legally allowed to use radar detectors in Virginia and Washington DC. A Word of Warningīefore explaining how to pick a good radar detector, I think it’s important to point out that radar detectors are not universally legal in North America. I’ve also tested enough detectors over the years to get a sense of what makes them good or bad based on their controls and feature sets. As editor of Car Audio & Electronics magazine, I coordinated an annual radar detector test and have kept my eyes and hands on the products ever since, keeping tabs on new technology and features. Show more The Expert: I’ve spent my entire journalism career testing car electronics and have owned several radar detectors going back to the mid-90s. How to Pick The Right Motor Oil for Your Car Best Radar Detectors.More guides for gearheads: The Popular Mechanics Auto Awards Picking the best radar detector can be tricky, so we’ve scouted them out for you. Unsurprisingly, that means that some are better than others, and different models may work well for different drivers. Radar detectors rely on antennas and a microprocessor to track and analyze signals accurately from far enough away that you can actually use the information it provides. ![]() Some also sync with smartphone apps that can alert you to traffic or an accident on your route. ![]() That said, they also frequently feature other useful sensors, such as GPS, which marks the locations of nearby red-light cameras. Yes, they can help you avoid a speeding ticket-and a potential spike in your car insurance premiums-by revealing the presence of various types of police radar and laser signals. You don’t have to be a speed demon to reap the benefits of a radar detector. ![]()
