Best Undetectable Radar Detector 2022

An undetectable radar detector is an important part of car ownership that you should consider since it can protect you from radars and lasers used by the police. Because police can detect a radar detector in your car (although it’s only illegal in a few states), having one puts you one step ahead of law enforcement. Despite the increasing number of options available, it is imperative that you choose the detector carefully. We created this guide so you can find the best undetectable radar detector 2022 on the market.


Stealth radar detectors are undetectable radar detectors, which means they can be windshield-mounted radar detectors that cannot be detected by other radar detectors, such as police radar detectors. The stealth feature usually comes as the Vg-2 or Spectre signal detection.

Best Undetectable Radar Detector 2022:

1. Radenso XP Radar Detector with False Alert Filtering

Radenso XP Radar Detector

Radenso XP is the best undetectable radar detector in 2022. It offers some relief from the false alarms that plague radar detectors today. It has GPS, which is the only way to deal with commercial radar-controlled automatic door openers. Satellite technology allows users to add a door opener’s frequency and coordinates to its database by simply pressing a button. Next time you approach, the detector knows to be quiet. Radar signals near locked-out locations are treated as threats, so the detector goes off when a new signal is spotted.

When an escort passes a door-opener a few times, it will lock it out automatically. This is referred to as AutoLearn. The patent on this feature belongs to Escort, and other manufacturers, including Radenso, require a button press.

In addition, the XP comes with features to deal with a much bigger nuisance, the Blind Spot Monitor (BSM) radar. Radar spots adjacent lanes, alerting the driver when a lane change may be dangerous.

Detectors have become ineffective due to BSM, which is so common. BSM radar looks like police radar to a detector. It takes sophisticated software to distinguish the two. Without it, false alarms are almost constant.

2. Uniden R3 EXTREME LONG RANGE Laser/Radar Detector

Uniden R3 EXTREME LONG RANGE Laser Radar Detector

Uniden’s R3 Extreme Long Range Radar has an extremely high sensitivity. It also has a simple user interface that makes it easy for you to master its controls. In addition, its compact size makes it ideal for quick viewing and easy installation on the windshield.

The best feature of this radar is its ability to detect other radars from afar and its alert prompts are almost always early, which can be 40 meters ahead, giving you plenty of time to slow down. Also, it can work even when the source point is curved, mountainous, or near a river. Additionally, it can work off-axis.

The false alerts are rare with this Uniden R3 and the more you use it, the more accurate the alerts become by memorizing the database.

GPS is one of the most important features of the R3. It allows features such as location locking and user marks. These features are especially useful for local drivers. You can mark known speed traps so that you are reminded of them regardless of whether or not law enforcement is actively using radar.

3. Escort Redline EX Laser Radar Detector

Escort Redline EX Laser Radar Detector

The Escort Redline Ex is currently hailed as the best undetectable radar detector 2022 on the market. Here are two reasons why.

One, this is as close as we can get to a completely undetectable radar detector. Two, the Redline Ex has one of the longest tested ranges of radar detectors currently available.

The Redline Ex (as well as its predecessor, the Redline) stands out from the Escort roster with its proven claims of undetectability. Escort’s TotalShield RF technology is a patented feature on the Redline Ex. The device is therefore undetectable by old RDDs such as the VG-2 and Spectre, including the Elite.

Most radar detectors can’t go invisible against powerful RDDs like the Spectre, but this one can.

Just to clarify, all states in the US except Virginia and Washington DC allow the use of radar detectors. Many mid-range devices have cloaking against the once-standard VG-2.

In addition to detecting the most common signals such as Ka, X, as well as international bands such as Gatso, Strelka, and Multaradar CD/CT, it can also detect laser signals in any direction.

Performance is comparable to the older Redline model, but the Ex edges it out in two areas: false-alarm filtering and protection against red-light cameras and speed traps.

4. Uniden R7 EXTREME LONG RANGE Laser/Radar Detector

Uniden R7 Extreme Long range laser radar detector

The Uniden R7 Radar Detector is a multidirectional laser detector that simplifies your driving experience. With a new processor that is almost 50% faster than previous models, the R7 may be the best undetectable radar detector 2022 on the market.

The device combines all the best features available in top-rated undetectable radar detectors with high-end multi-directional technology.

Uniden’s R7 Radar Detector is made for every vehicle owner who does not want to face speeding issues along the way. The device provides real-time threat alerts from four different directions using advanced features.

5: Cobra RAD 480i Laser Radar Detector 

Cobra RAD 480i Laser Radar Detector

Laser detection from both front and rear, different sensitivity modes, and real-time alerts via the iRadar app: these are just some of the features that make the Cobra RAD 480i portable radar and laser detector a near-steal. Even though it offers a good array of features for the price, our overall opinion is mixed after three weeks of driving the 480i through Michigan, Ohio, and Indiana. It’s not a lousy radar detector. It’s more about whether the RAD 480i is the best choice given all the other options. 

Cobra RAD 480i is equipped with a 12V power cord, suction cup windshield mount, hook-and-loop fastener for dashboard mounting, and a quick reference guide.

With the Cobra RAD 480i, you will be alerted to radars operating in the X, K, and Ka bands as well as lasers (LiDAR guns). Using Cobra’s proprietary LaserEye technology (located on the top left of the unit), the RAD 480i can detect signals from both the front and the rear. The best placement for it is on the front windshield (approximately) in the center of your vehicle. It should be as low as possible without obstructing the view, either front or back. The LaserEye should have a clear view out of your rear window to ensure maximum coverage.

RAD 480i is also VG-2 capable, meaning it can identify the infamous “radar detector.” Radar detectors emit a low-level signal that VG-2 can detect. In contrast, the RAD 480i does not emit this signal, making it invisible to radar detector detectors (which may explain why the default factory setting for VG-2 is off).

Item Weight: 12.8 ounces

Special Features: Laser Eye, IRadar App

Other display features: Wireless


  •  Digital signal processer that helps to provide an accurate alert

Q: How much should I spend on a radar detector?

Ans: As with many high-tech electronics, the more costly the device, the better it likely will be; according to Newcomb, the sweet spot for radar detectors is between $200 to $450. “Typically, you’ll get better features, better technology, and better components” the more you spend, he says.

Q: Where should a radar detector be placed in a car?

Ans: The radar detector should be mounted as high up as possible in a vehicle to have a good radar detection range. Radar detectors are typically mounted on the vehicle’s front windshield near or around the center of the rearview mirror.

Q: Is a radar detector a waste of money?

Ans: As long as there is a surface to reflect it, the laser point is so small that any surface can hit it. Therefore, please don’t waste your money on detectors since they are not as useful as they once were, and when you get caught, you’ll have to pay a ticket and the cost of the detector.

Q: Do magnets affect radar detectors?

Ans: Magnets should not affect the radar detector. Nor should metal be nearby. As long as the detector itself has a clear forward FOV (some detect rearwards, too), then it’ll work fine.

Q: Can you mount a radar detector upside down?

Ans: You can mount it upside down just fine. You won’t have any problems. Make sure that your RD has a clear line of sight to the road and that no metal supports, braces, or metallic paint are in the way.
