Best Radar Detectors in 2021

A radar detector is a compact electronic device that detects and informs the user about the presence of radars emitting radio waves or laser beams on the road. Basically, it’s a passive receiver that does not muffle signals.

Using radar and laser detectors is allowed in the U.S. The reason for this is that the device helps drivers to stay mindful on the road and control their speeds. Even considering the fact that laws vary from state to state, private vehicles are allowed to have radar detectors almost everywhere.

If you don’t have time to read the whole article, the best radar detector in our opinion is the Escort Max 360. It will make your driving peaceful and save you from any ticket threats by providing full 360-degree protection. This high-quality device features front and rear-facing antennas and knows exactly how to detect the threat in the most accurate way. 

How to Choose a Radar Detector

Here are a few main points to pay attention to when choosing a radar detector:

  • Construction type. Plus, you can choose from monoblocks, block structures, and combined detectors. The first option is the most popular, due to its ergonomics. The controls, hardware, and display are all in one housing. Block constructions include 2 modules – one contains sensors and another one contains parts. Combined models are equipped with additional features, e.g. a video recorder.
  • Complete set. Basic sets typically include the device itself, mount, charging cord, and USB cord to update the software through your computer. Some radar detectors also have a special connector to recharge your smartphone or DVR (dash cam).
  • Sound notifications. Not all models have volume control and a mute function. Notifications can also be male/female voice, short/long phrases.
  • Frequency range. All modern devices support all necessary frequencies, from 10475 MHz to 36000 MHz.
  • Operating angle (in degrees): all directions (360), oncoming, passing through.
  • Installation method. You can find models with sticky mounts, Velcro, and rubber mats. The first option is the most reliable. There are also built-in and non-built in radars.
  • Basic functions. Simple affordable models have a common set of indicators without a display. Middle-class radars are equipped with a display that provides more detailed information, including a distance to the radar. Premium devices have built-in GPS modules, better cope with interference, and are able to accurately determine radars at a considerable distance. Moreover, they display useful information, e.g. real speed, various modes, etc. 
  • Regional linking. Radar detectors designed by famous brands typically have a relevant geo-base, which is very useful.

Best Radar Detectors on the Market

The Max 360 – Best Escort Detector

For those of you who are used to rapid responses and a great number of features, the Escort MAX 360 will be as impressive as functional. Not only it features the Dual Antenna System but also detects X, K, Ka radar frequencies, and laser signals at 360-degree coverage. The device uses 360 Directional Alert Arrows to quickly and accurately indicate where the signals come from. It also comes with a convenient OLED display to provide as much useful information as possible.

There’s virtually nothing this smart device can’t do! Its GPS intelligence, along with IVT filtering, and AutoSensitivity, allows you to mark known speed traps on your route, plus, the detector learns from your route and varying sensitivity with vehicle speed to automatically block false alarms in the future (AutoLearn Technology).

The new Escort Max 360 will cost you $499.95. You can also get a bundle that includes the main device + the Escort Radar M1 Dash Cam at $699.90. You can also sell your old Escort radar detector (Trade-In Program) and get credits towards a new device.

How can you set up the Escort Max 360?

You can set up your Escort Max 360 in 2 ways – through the device itself or through your phone. 

  1. Press and hold the Brightness button (BRT) on the left and the Sensitivity button (SEN) in the middle to access the main menu. You can press the BRT button again to access different menu options, including Pilot Mode, Arrow Mode, Display Color, etc. If you need to adjust a certain parameter, you press “+” or “-” (Volume controls) near the MRK button. For instance, you have 4 different color options to choose from. Once you’re done, you should press the Power button to make your choice.
  2. Alternatively you can also make adjustments through your smartphone if you download the ESCORT Live App for Android/iPhone, which is more convenient and looks better. After you pair it to the detector, go to the Settings page and check all the different options you can choose from. 

There are many functions you can “play” with. There are different brightness modes, e.g. the Auto mode that will automatically make the screen brighter or darker during the day or at night. You can choose the Dark mode to keep your radar’s display totally black, and it will alert you through sound alarms. In this case, your phone’s display will be your “eyes,” which is really handy. You can also choose the best Sensitivity mode (“Highway”) to get the best performance, i.e. the best sensitivity on all radar bands. In its turn, the Auto mode will help you handle some of the false alerts when driving around the city. AutoNoX is almost the same as Auto mode but it also additionally disables X band radars (which can only be needed if you live in New Jersey, Ohio, or Oregon). Moreover, you can also choose how the radar will display information about multiple alerts on the screen. 

There are many other important and interesting features of the radar to check – you can read about them all in the Owner’s Manual here.

Radar Detector FAQ

Are radar detectors still effective?

Absolutely! High-quality radar detectors, which detect both red-light cameras, speed cameras, and lasers, are complex devices that are easy to use. These radar detectors are designed to save you from radar and laser guns in a truly wide range. A radar detector designed by professionals can detect a signal sent by a police radar even before it bounces off the object (in front of the vehicle) and returns to the radar. Yes, a good radar detector is a really useful thing and a must-have that will save you from speed tickets and allow you to focus on the road.

Are radar detectors worth it in 2020?

Definitely. Radar detectors have no analogues to date, but new features appear quite often. New advanced devices include a well-developed base of fixed cameras, many also come with lifetime upgrades and unique features for the best performance. Additionally, most radars have adjustable sensitivity and software algorithms for elimination of false alarms. If you live in a big city and often drive on highways or unfamiliar routes, then you definitely need a radar detector. In addition, you can use it through convenient mobile apps with excellent functionality. They will facilitate the setup and use of the device.

Which radar detector has the longest range?

Undoubtedly, Escort Max 360.

Can a cop tell if you have a radar detector?

Yes. And it’s not that the device itself can be detected by a police radar. But because most drivers will start braking when a cop turns on the radar, they give themselves away. Meaning that the headlights dip down or brake lights come on, indicating your awareness. But if you’re not living in Washington D.C. or Virginia, you have nothing to worry about.

What should I look for when buying a radar detector?

Aim for a well-known brand (Escort, Valentin, Uniden, Whistler, Beltronics, Cobra, etc. Check the detection range and if the device provides full 360-degree protection (dual antennas, long range, X, K, Ku, Ka, and Super Wideband Ka detection, etc.). Make sure your chosen model has every function you need, depending on your driving routes, style, and other conditions. Voice alerts, adjustable modes, sufficient sensitivity, frequency range, convenient installation method, and ease of use. Last but not least, check if there’s a USB cord included and the software can be updated through your PC.

How can I hide my radar detector?

The most expensive way is getting a stealthy radar detector that features a radar detector detecting technology (the one that can hide from RDD-equipped radar guns). These detectors are designed mainly by Escort, Uniden, and Beltronics brands. Secondly, you can simply mount your radar detector right above the rear view window to make it less visible. But the main thing to remember, is to stay calm and do not slam on those brakes once you get an alert.

What does “Ka” mean on a radar detector?

This is the latest type of radar band frequency on the market used by police these days. Ka bands operate on radio waves between 33.4 GHz and 36.0 GHz. It is considered to be the most promising range due to the even shorter period of time and higher energy potential, allowing these devices to have a detection range of up to 1.5 km with high accuracy in a very short time. This range has the widest bandwidth (1300 MHz), so it was called SuperWide (super wide) and the complete absence of household and other obstacles that interfere with the speed determination of the targeted object.

Where should a radar detector be mounted?

The best place is on your rear view window. Mounting on the windshield is illegal in some states.

Does Window Tint affect radar detectors?

Yes. It’s like you cover your radar detector with a blanket. The thing is that some tinted windshields use metal, polymer, or ceramic films, coatings, etc. which are not good for radar microwave signals. Plastic and fiberglass can be OK at times, but metal is a different story. This can negatively affect the ability of your radar detector to detect a laser gun.

Do truckers use radar detectors?

No. Commercial truck drivers can never use a radar detector as it breaks the FMCSA (Federal Motor Carrier Safety Administration) law.
