6 Best Radar Detectors for 2021 Reviews & Buying Guide

While speed limits have been put in place to ensure our safety, it might not be possible to follow them in all circumstances.

But when you do break the law, you have to do it right and ensure you don’t get into trouble. You can be detected by a speed trap and end up with a ticket from the law enforcer.

To prevent this from happening, your best bet is to use a radar detector. A radar detector picks up speed traps well in advance and alerts you. So that you can adjust your speed and get past the speed trap without any trouble.

The key to choosing the right radar detector lies in understanding your needs and driving preferences.

For instance, if you want to use the same detector for different cars, you have to go with a cordless detector. Then there is the question of choosing the right mode based on whether you are driving in the city or highway or urban areas.

The following passage answers all these questions and helps you understand the primary things you need to check while buying the perfect radar detector.

Radar Detector Types: There are three types of radar detectors – corded, cordless, and remote-mount.

The corded detectors provide the best range and are mounted on the windshield via suction cups. The cordless ones can be used for multiple cars and can be installed easily. The remote-mount detectors are permanently installed on your cars.

Depending on whether you want to use the detector for single or multiple cars, you can buy the right one.

Detection Mode: There are two detection modes – Highway and City mode.

Highway mode provides the default level of sensitivity while City mode has decreased sensitivity. When driving through urban areas, it is better to switch to city mode. This will reduce false alarms from similar source signals of radar guns such as automatic door openers.

360-Degree Detection: Some radar detectors come with only one laser sensor. Using this, you can only detect radar guns in front of you. But the ones that come with two laser sensors can detect radar guns to the sides and behind you.

We highly recommend you go with the 360-degree detection radar detectors.

While these are the primary things you need to check, there are other certain features you should be aware of before finalizing the best radar detector. You will find the complete list of these features in the “Buying Guide” section of the article.

But to keep things simple, we have done the work for you. We have prepared a list of the Best Radar Detectors 2021 by considering all the features. Do check it out.

Factors to check while buying the Best Radar Detector

This section throws light on more features you need to check while looking for radar detectors. Not every feature may be useful to you. So, understand your needs so that you don’t end up purchasing an expensive radar detector.

Below are the different features you need to look for in a radar detector,

In-Built GPS

With the in-built GPS feature, you don’t just get to know your position and how fast you are driving. But, you can program them to remember areas with frequent speed traps, red lights, and speed cameras, and alert you.

In this way, you have an ample amount of time to adjust your speed before entering the speed trap-prone area.

Besides, the radar detectors can automatically switch between city and highway modes depending on your speed. You do not have to check the mode manually. You can also program it to alert you when you cross a set speed limit for your own safety.

Instant-On Protection

A radar detector can not protect you from an instant-on radar. An instant-on radar will measure your speed instantly as soon as it is pointed at your card. It is near-impossible for any radar detector to give an alert within this timespan.

But, some radar detectors with high K-band sensitivity will detect when the radar is pointed at the car ahead of you. It will send out an alert and will give you enough time to lower your car speed.

Voice and Visual Alerts

Having a radar detector that sends voice alerts will improve your safety. You do not have to take your eyes off the road. But, if you have passengers sleeping in your car, the voice alert will disturb them. In that case, a visual alert would be the best option.

We recommend you get a radar detector that has both options. You can then choose what kind of alerts you want to receive depending on the situation.

Shielding against RDD (Radar Detector Detection)

In some states, it is illegal to use any kind of radar detectors. But that does not prevent people from using it. If you still prefer to use it, you have to opt for a radar detector that can shield against detection.

The radar detectors will shield itself either by becoming invisible or shutting down completely when it senses an RDD device. Before shutting down, the detector will send out an alert so that you can adjust your speed.

There are three RDDs (Radar Detector Detections) to find if you have installed a radar detector or not.

VG-2: One of the oldest RDD techniques that work by detecting oscillations only on a single frequency band. You will find a lot of detectors in the market that can shield against this technique.

Spectre:  Newer technology that can detect oscillations on several frequencies and pickup more emissions from a detector. Even though it is difficult to shield against this technique, you can still find models that will become invisible in the presence of Spectre devices.

VG-2 and Spectre: Ideally, you would want a radar detector that shields you against both VG-2 and spectre. Both techniques are used to pick up radar detectors. So, buy a radar that offers shielding against both RDDs.

Display Type

If you are using a detector that shows visual alerts, then the display type becomes important. With the detectors, you get three main display types such as OLED, LED, and ultra-bright.

We recommend you go with the OLED display as the alerts are visible clearly. But, if you are living in a state where using radar detectors is illegal, it is best to go with an LED for discretion.

Smartphone Compatibility

As with all other electronic devices, you can also connect your radar detectors to your smartphone. Brands offer iOS and Android apps that allow you to connect your radar detector and smartphone together.

You get two main advantages when you connect them together. First, the radar detector will send alerts through your smartphone. This allows your detector to be more discreet.

The second is that you find speed trap locations on your route. The other users will mark the locations when they come across a speed trap. So, you can find the most recent speed locations.

Conclusion

If you want a radar detector that is capable of detecting all speed traps and comes at an affordable price, then Uniden R3 long-range radar detector would be the perfect fit for you.

If you reside in a state where the use of radar detectors is illegal, then the Cobra XRS9370 radar detector is the best option for you. It provides shielding against both VG-2 and Spectre technique. Besides, it has 360-degree detection and comes with a dedicated Pop mode for faster detection.
