Avoid Speeding Tickets with These Top Radar Detectors
What's the best radar detector? With dozens on the market, choosing one that lives up to its promises can be daunting. The Gear Team scrutinizes the details so you don't have to.
Radar speed-detection capabilities were first developed in 1935 by a Bobby in Britain who had his eyes set on your wallet. Some 30 years on, a fed-up comrade and engineer invented one of the earliest radar detection devices, known as the Fuzzbuster. Now, in 2023, law enforcement has stepped up its speed-detecting game—but so have the good folks who manufacture countermeasures.
Radar detectors can be useful to anyone, regardless of your inclination to speed. They can save you from costly speeding tickets and higher auto insurance rates by alerting you to the existence of different police radar and laser signals. Some of the latest devices frequently incorporate helpful sensors, such as GPS, which identify the locations of red-light cameras. Some can connect to mobile devices and notify you of traffic or accidents along your path.
Radar detectors utilize antennas to monitor and analyze signals from a distance. Naturally, this implies that some are superior to others and that various models may suit certain drivers. It can be difficult to choose the best radar detector, therefore the Gear Team has stepped up to handle the research for you.
Things to Consider
How they work: Whether your detector uses antennas, microprocessors, or some combination of both, the receivers in your detector tune into active radar signals. The X, K, and Ka bands are the three types of radar and laser most frequently used by law enforcement in the U.S. For many years, law enforcement relied heavily on the now less common X-band. K-band, its replacement, is more challenging to detect from a distance, in part due to its higher frequency. Ka-band is the hardest form of radar to detect at a distance because it has a narrower beam pattern and lower power output than both X and K bands.
Range: A radar detector that will alert you of an approaching checkpoint far enough in advance for you to slow down is necessary. The range of your radar detector effectively dictates how valuable it can be. While some devices can only detect radar 100 feet away, others are able to warn you well in advance. Interference can decrease the effective range of a detector due to things like weather and solid objects. Because of this, many manufacturers refrain from providing you with a detector's actual range and instead rely on generalizations like "long range."
False-alert filtering: Sometimes, radar detectors will mistakenly detect radar signals from other devices. There are a number of variables that can trigger false alerts, from sensors on another vehicle and radar-controlled garage door openers to various radio signals. Most radar detectors feature a mute button so you can manually turn off false alarms. Some of the latest software is used to filter out frequent false signals by learning where they commonly occur.
So what's the best radar detector you can buy? Without a complete and thorough test—which is forthcoming—it's really impossible to say. However, we can bring you a selection of top brands and personal favorites, hand-picked by the editors of Hearst Autos.
