Best Cordless Radar Detector Buyers’ Guide 

Function of a radar detector

Knowing the police radar signals is an essential undertaking for most drivers, especially when you are on a highway and having an emergency and need to speed to reach your destination within the shortest time possible.

The radar detectors help you listen for the broadcasts on the bands that are possibly police radar signals. In the process, they will let you know the strength of the signal and the band that the police are receiving.

The information is vital as it helps you determine the location of the police radar or surveillance from where you are; that is, it helps you know your distance from the police surveillance, and this can help you lower the speed when you were over-speeding.

Once you have known the distance of the police radar, you will have enough time to hit the brakes. Thus, it gives you an alert to keep you from falling on the wrong side of the law.

How radar detector works

The radar detectors work on the same concept as that of the radio bands that can vary in frequency and shape. The radar detectors are used for speed detection.

Initially, the police shoot a beam across the section of the road that they want to monitor. The beams are a police broadcast at various bands that can be X, K, or super-wide ka. The bands can get associated with those of the AM or FM radio bands as their wave-shape or frequency can also vary. 

When the radar band hits an object that is moving, it will come back to the source gun with a different frequency. Depended on the difference of the frequency, you can effectively determine the speed that the object is moving. This is vital for the traffic police who monitor the speed limits on the roads.

The below video shows how escort solo S2 cordless radar detector can be used to detect the presence and distance of the police’s radar

Factors to Consider When Buying a radar detector

Getting the battery operated radar detectors can be a tedious process. You have to browse through long lists of products that may appear similar but have very unique features and performance scores.

 Besides, manufacturers are actively releasing new models of radar detectors that contain the latest technologies. However, we have prepared this simple guide to help you overcome these challenges and successfully get the best budget radar detector. The following are a few things that you should consider when thinking about buying a radar detector. 

Performance 

The purpose of using a cordless radar detector is to avoid being caught and pulled over for over speeding. A good cordless radar detector should, at the minimum, effectively detect mobile and static police surveillance points. But more than this, the best cordless radar detector should not be easily identifiable by the police. Using a radar detector is unlawful in some states. 

Most modern-day detectors are effective in identifying and alerting you about police radars by a range of more than 2 miles. Additionally, they can pick up signals that come in from any direction. This detection range is good enough for anyone who is driving through a busy city street or on a highway. 

Radenso XP, Whistler CR93, Cobra RAD450, and Escort Passport 9500iX have a 2+ mile and 360-degree detection range. They can effectively pick up radiation from any direction within their range. 

The ability to choose different band frequencies is an important feature that you can use to assess the performance of a radar detector. Radars work by detecting the frequencies that are emitted by police speed guns. There are three main bands of frequencies that police radars use: K, X, and Ka. within these major bands are smaller frequency levels that police radars use for detecting and measuring the speed of your car. 

A good radar has an option for operating at very low and high frequencies. However, manufacturers are careful enough to ensure that the detectors do not end up picking all manner of frequencies.

However, having a cordless radar detector that can operate across the three bands can be beneficial. The best detectors, such as Whistler CR93, Uniden DFR8, and Escort Solo 3 can effectively and accurately detect low and high frequencies across the three bands. 

Moreover, excellent radar detectors can operate in the stealth mode to avoid detection by the police. The Whistler CR93 can escape detection by the police within a range of 14 miles. It is very easy to activate stealth mode and successfully avoid detection.

Ease of Use 

One of the things that determine the level of user experience of a cordless radar detector is the quality of the voice control feature. Although it is nowadays an industry standard for cordless radar detectors to have voice control, the quality of the voice commands that they give varies a lot. You need a radar detector that gives you audible alerts about the possible location of speed guns while driving. All the six types of radar detectors that we have reviewed have high-quality voice control features. 

Similarly, the six cordless radar detectors that we have reviewed have OLED display functionality. The OLED functionality is simpler and clearer than the LCD system. When driving on a busy street or highway, you will find it easy to read important information on the OLED screen of your radar detector.  

Ease of Installation 

The ease of mounting and ability to withstand vibration is another important factor that you need to consider when buying a cordless radar detector. Most detectors that we have covered in this review can be easily mounted either on the windshield or dashboard of your automobile. The Radenso XP comes with very clear mounting instructions. Besides, you only need to get it out of the box, mount it on your windshield, and start using it immediately.

It is common for some radar detectors to get loose after some time. This is as a result of the constant vibration that they have to endure when mounted on the dashboard or windshield. Although you can easily purchase additional mounts from the aftermarket, you would not want to keep on remounting your radar detector after a few weeks. Therefore, go for a product that has very strong mounts and can withstand constant vibration that comes with driving.

GPS Functionality 

Cordless radar detectors that have a GPS-enabled filtering functionality are better than those which do not have this feature. The GPS functionality helps you to optimize the way your radar detector works according to your behavior. If activated, this feature detects and records false sources of alarms, thus preventing a repletion of false alarms from many other sources of frequency. 

Frequently Asked Questions on Radar Detectors

What is the difference between the Ka and K band on a radar detector?

Indeed, most people cannot effectively differentiate the Ka and K band in the radar detectors. For instance, in this article, I have reviewed certain models such as Escort Solo 4 radar detectors that provide warning of all the radar bands, including the instant-on K band and the super-wide Ka-band. It has been a challenge for most people to distinguish when to use the Ka-band or K band. However, the meaning and when to use the two should not be a worry anymore after reading this article.

In the radar detector unit, the frequency covering between 18GHz and 27GHz is called the K band. On the police radar, the k band operates between 24.125 GHz and 24.15GHz. This implies that if the radar detector you are using has a k band coverage, you will get alerts when the k band radar is getting utilized by the police, allowing you to react right in time.

On the other hand, the Ka-band refers to the frequencies between 26.5GHZ and 40 GHz. Thus, if you activate your radar detector model and observe the Ka warning getting displayed in your OLED, you should know that a radar gun using that frequency range is used by the police.

How far radar band signal can a Radar Detector Sense?

This is another common question that you might ask yourself before you buy a radar detector. Most of the units I have reviewed in this article can detect between 2-3 miles while other units can detect up to 4 miles.

The vehicles’ speed is often measured at around 1000 feet away, which is a representation of about 1/5-mile distance. In such a huge distance, the laser beam is over 3 feet when it notices or picks your vehicle up.

Moreover, if an X-band radar is activated, it can detect objects or signals 2 to 4 miles away. The X-band radar can reach this range due to its low frequency and high output, making it sense objects at greater distances.

Can a Radar Detector Picks Up a Speed Camera?

This is another common question that most users or the individuals aspiring to own a radar detector always ask.  The radar detectors cannot detect fixed speed cameras. The fixed cameras on the road sides don’t transmit frequencies captured or detected by the radar detectors. Instead, you should have a GPS to help you locate or detect the fixed cameras’ locations.

It is noteworthy to purchase a radar detector model with a GPS to determine the fixed camera locations. The GPS systems are always built-in the radar unit. The radar detectors with no GPS cannot detect the location of the installed cameras by the roadside.

Where should you Place a Radar Detector?

Even though this is also a common question with the individuals buying the radar detectors, it is important to note that the radar detectors come with the instruction manuals where the manufacturers have recommended where to mount your radar detector.

However, you should ensure that your unit is mounted centrally in your windshield. The practice is recommendable since the central position is a compromise between the high and low mounting positions. The central position also provides an unobstructed front and rear detection coverage.

Even though you can decide on the central area where you want to mount your radar detector, you should always have in mind that regardless of the mount’s place, do not obstruct your driving view.

Conclusion 

Over-speeding can be costly both when you get pulled over or it can result in an accident that can lead to death or damage. However, sometimes you find yourself over-speeding not because you want to defy the law but you can be caught up with an emergency that only you will understand the need for the hurry. 

In such an instance, it would be better if you have a device in your car that can help you identify the installed or mobile surveillance to keep you out of trouble. Choosing the best cordless radar detector can help you get accurate alerts to ensure you are not found on the wrong side of the law. The best model that will serve you right and within your budget is Escort Solo S4 Radar Detector. The unit is not only efficient, but is also characterized by high performance.

With my selection of the top models available in the market today and the buyers guide to help make purchase decisions, I hope you benefit from this article.
