Best Cordless Radar Detector

As we all know, having to get a speeding ticket is something that has never been fun, and taking steps to make sure that we do not get one is a wise move on our part. And as such, having a good radar detector on the dashboard has become really common among many motorists.

By making use of these little electronic devices that will help detect police radar guns, one can do well to avoid unnecessary fines that may otherwise occur, while one still stays safe. The radar detector is just a small electronic device that scans its surroundings, looking for radio frequencies that are emitted by police speed radars and other hazard devices.

Once this device detects any of the above, it will alert you visually or with a sound or even both.

In this article, we will be giving you a review of the best cordless radar detectors that are available on the market, as this will help you make the right decision when it comes to safe driving.

What is a battery powered or a cordless radar detector?

The battery powered radar detectors come with all the mod-cons of a regular plug-in device, but they do not come with those distracting, annoying cables. All what you need to do is to attach it to your car’s dashboard or its windshield, switch it on and you begin your drive.

These devices are a great accompaniment for the drivers who use multiple cars, since they are very small, easy to transport, and they are also simple to configure. Some models available on the market have a very long battery lifespan, and what this means is that you get more driving time, and you would be required to spend less time pulling over to recharge or switching batteries.

Different Wavelengths and Bands


So that you can get the best results, your radar detector must be sensitive to three main radar frequencies. The X-band radar is the lowest in terms if frequency, but it is high in output, with the radar waves that fall between 7.0 and 11 Gigahertz.

What this means is that it is easy for you to detect at longer distances. Although, the X-band is the oldest type of wavelength that is used in police speed guns and it isn’t widely used again.

Any device that is other than the police radars can produce or emit X-band signals; and most of these devices could be garage door openers, weathering monitoring equipment, blind spot monitoring systems, microwave towers, and many other modern radar technology.


This was adopted by the police service just a few decades ago, K-band is a higher power alternative to the original standard, which is the X-band. The K-band has quite a shorter wavelength, with a frequency of 18 – 27 Gigahertz, and it is in the microwave range of frequencies.

Because of the K-band’s shorter wavelength, the original K-band was been sectioned into three other wavelengths, Ka-band, K-band, and Ku-band.


The Ka-band; this one which was introduced in the year 1983, is what is called the new kid on the block. It has frequencies that are found in the microwave segment of the electromagnetic spectrum. The ka-band is a bit more complex than its contemporaries – the X and K, and it also exists within the frequencies of 26.5 – 40 Gigahertz, so wavelengths over one centimeter to just 7.5 millimeters.

The much older police radar guns that operate on either X or K-bands do so only at the frequencies of 1 or 2. Ka runs on as many as five frequencies. When getting a radar detector, it is prudent that you get the one that can detect as many wavelengths, and that has laser detection.

  1. Cobra ESD 7570 – The Best Affordable Radar Detector

The Cobra ESD 7570 will not break your bank, but it comes with some serious punch. It is a sleek-looking product and it is also compact it can be mounted to your windshield using suction cups, and it also comes with an easy-to-read display that shows you data clearly even in bright sunlight.

This model’s display is broken up into color-coded sections for the numerous bands that are used by law enforcement so that you can immediately be notified of what it is you are up against.

The city/highway mode is one handy feature. When you are in a densely populated area, store alarms and other signals can sometimes set off a radar detector. Turning on city mode helps to reduce these false alarms. When you are on the highway, especially when you are out in the rural areas, signals almost invariably come from law enforcement; a cactus certainly will not set off a detector. Highway mode takes that into account.

This model’s 360-degree detection that is called the LaserEye helps to detect signals regardless of where they are coming from. The ESD 7570 will alert you if the signal is coming from behind your car. It also comes with safety alerts when it detects the presence of an emergency vehicle, like an ambulance, or when it senses that you are approaching a railroad crossing, among other hazards.



  1. Valentine One V1 – The Best Mid-Range Radar Detector

This model’s interface and display look like they are from the 90s and that is because they are, but the device is one of the best radar detectors on the market. It comes with two rear antennas, an impressive range, and laser detection, this model helps to keep your driving record as clean as a whistle.

The device’s greatest feature is perhaps its directional notifications of upcoming radar signals. While many radar detectors on the market only alert the driver of radar signals in the local area, Valentine One’s model tells the driver of the exact direction the radar signal is coming from. Making use of a front and rear radar antenna, drivers can see just where a speed reading is coming from and what kind of band it is using.

If the arrow on the top of the device activates and the Ka category lights up, a police speed trap lies ahead of you. You will know you have passed it once the arrow pointing down lights up. The Valentine One makers held a patent on arrow indicators until the year 2011, and the Escort Max 360 features a similar system.

Even a radar detector as impressive and as helpful as the Valentine One comes with a few downsides. While this drawback is not totally damning of the product completely, it does tend to overachieve when it comes to searching for radar signals, even when it comes to non-police radars, they have a tendency to set off the device. But such a drawback on an otherwise great model should not make you turn away from making this your go-to radar detector.

In fact, many people would rather have a radar that overcompensates at its job than one that fails to alert you even the most obvious speed traps.

This device also comes with the ability to turn off the X or K band detectors, though, you should proceed with caution as some police still make use of the lesser-utilized K band from time to time. With reliable, straightforward alerts and its unique arrow display system, the Valentine One Radar Locator is at the top of its class.



  1. Escort IX – The Best Mid-Range Radar Detector

Although the name of this model suggests that it is an old car equipped with an even newer and stronger car’s all-wheel drive system, the Escort IX is one radar detector that is tailor-made for long-range detection. It is well suited to remote areas like the Nevada desert or the Great Plains, since it detects speed traps from far away.

When this device goes off, you know that there is a law enforcement officer in the area. The IX’s early warning gives you enough time for you to slow down to a more allowed speed, and its easy to read display tells you just how much speed you need to cut down on.

The IX’s multiple sensors detect X-band, K-band, and Super Wide Ka-band, even if the officer is using some highly alert technology. It is also smart, this device. Its Intelligent AutoLearn technology relies on GPS and frequency data to reject false alarms and also learn their location so that it does not go off the next time you drive past them.

It also comes with an inbuilt IVT filter, and this feature helps to reduce false alarms caused by in-vehicle technology like the adaptive cruise control and collision avoidance systems. This certainly was not a problem a few years ago, but it has become a real issue since cars get more and more technologically advanced.

Users of this model can synch it with the Escort Live application so they can receive crowd-sourced real-time alerts of speed traps, red light cameras, and other traffic-related threats. The app is compatible with Android and Apple devices, and it is free.

In Conclusion

There are no two people that drive the same way, so, when you are trying to get a radar detector, make sure that you get one that is adjustable to your driving style. We hope that with this guide, you have been able to get sufficient guide toward your ideal cordless radar detector.
