The Escort Redline 360c comes equipped with automated features that help fight against false alerts. The triple antenna design improves range and accuracy, putting the 360c at the top of the pack. The device is designed to plug and go with various driving modes, automated features, and built-in WiFi, allowing instant shared alerts and software updates. The Escort Live! app updates every Monday, ensuring that new red light cameras and speed traps are up to date. Modes like Highway, Auto, Auto No X, and Auto Lo K allow you to adjust the sensitivity, cutting down on false alerts. The new K-notch feature also helps filter out blind-spot monitoring (BSM) from newer vehicles, and auto lockouts help keep the device quieter and hands-free. Visually, the 360c is very intuitive. The Graphic Multi-Color OLED screen uses a bar graph to display the signal strength, and there are five brightness levels with full dark mode, which is “great for evening driving,” our lead tester noted. This device also offers laser jammer integration (although this was not yet released at the time of this writing).
Even though the false alert filtering works impeccably, the 360c manufacturer's website includes some language claiming it never alerts falsely, which is simply not true. “No radar detector is flawless, but this one is pretty close,” our tester said. The alerts are informative, but the MRCD alert flashes arrows in all directions, making it challenging to determine which direction the threat is coming from. Also, this device is one of the most expensive radar detectors available. Still, this unit is worth the investment if you're searching for a high-range, accurate device that doesn't require too much fiddling to keep quiet. If a mid-range model is more within your price range, the Uniden R7 is a great option that lets you know the direction of the threat.
The Uniden R8 is an upgraded version of a previous iteration with significant improvements, including Bluetooth. “It is highly customizable, making it an excellent option for enthusiasts who are specific about how they like their detectors set up,” our tester mentioned. When programmed properly for your driving location, the R8 offers you complete control over the sensitivity of your device, significantly improving false alert filtering. The new bubble lens improves its range and accuracy, and the alert response time is also very fast, ensuring little to no lag between when a signal is picked up and when you are alerted of its presence. The R8 can also detect newer Gatso speed cameras. The R8s predecessor has the mute and mark buttons on the side of the device, which can be difficult to reach while driving, but Uniden placed them on the face of the R8, which is a huge improvement. MRCD detection is another area where this detector has significantly improved.
Though Bluetooth will be helpful, Uniden had not yet released its app when we conducted our testing, so we can't comment on this yet. The previous R8 version showed serious issues with auto lockouts, which this version still struggles with, although not as badly. “You can drive past the same strip mall or grocery store for months while continuing to experience false alerts from the automatic doors,” our tester observed. To mitigate this issue, you can manually lock out stationary locations such as these. However, auto lockouts are a sought-after feature, so it's a little disappointing that this model struggles with it. Furthermore, the R8 is not completely RDD (radar detector detector) immune. Fortunately, this is not an issue in most of the US, as radar detectors are perfectly legal. For such a top-notch device, you'll also pay a higher price. Overall, the R8 is a great daily driver if you understand the radar threats in your area and enjoy adjusting the settings to optimize the device. However, for a few dollars less, you can enjoy the better-performing auto lockout feature of the Escort MAX 360c.
As a company, Uniden is known for making long-range radar detectors, and the Uniden R3 is no exception. This highly customizable device does a stellar job of picking up all the desired frequencies with plenty of time to allow the driver to slow down. Not only does it excel in the range department, but its accuracy is also an attribute to write home about — “as long as you understand the optimal settings for your primary driving routes,” our lead tester emphasized. Uniden gives its users fine-tuned control over band sensitivity to help with false alerts. The R3 is user-friendly, especially once you become familiar with the controls, from the setup to updates to setting adjustments. The GPS location lockouts are recorded by a simple double-tap of the mute button, located just below the screen, and remain recorded until you delete them. The audible alerts are easy to hear, and the screen is easy to read.
We found the GPS location lockouts easy to perform and plentiful, but the R3 does not have as much storage as other devices, including other Uniden models. It won't affect the daily performance, but it may inhibit the use of future memory-heavy firmware updates. It also does not pick up modulating frequencies like some more expensive models. As such, the MultaRadar detection is lacking. Blind-spot monitoring (BSM) filtering is another issue we have with otherwise stellar R3. “Driving next to modern cars equipped with blind-spot monitoring often triggers the K-band alert,” our tester noticed. Fine-tuning the K-band sensitivity helps slightly but doesn't prevent all BSM-related false alerts. Lastly, the R3 does not have directional arrows. Though it's not a dealbreaker, we genuinely appreciate knowing the direction of the threat. With this device, you can feel confident that you're getting the most critical features of an advanced radar detector with excellent range and comparable accuracy at a portion of the price.
The Uniden R7 is an advanced radar detector at a very fair mid-high price point. “This model balances being highly customizable with simple settings adjustments to allow for a quick learning curve,” our lead tester described. It is accurate with excellent range — we could detect a cop over 5 miles away through winding mountainous roads. The built-in GPS technology offers several options to keep false alarms down, blocking alarms caused by radars found on things like automatic doors and train tracks. The manual lockout feature will allow the user to permanently mute any non-threatening, stationary trigger. You can store uploaded information like red-light cameras on the device, with firmware updates confirming those locations. The sizeable multicolored OLED screen is automatically brightened or dimmed based on a built-in ambient light sensor, and clear, unique, and crisp audible alerts round out this excellent package.
While the manual GPS lockout feature is an absolute star, there is still somewhat of a learning curve. For instance, locking out a location requires double-clicking the mute button. “The first few times we tried using this feature, we just wound up muting the device rather than locking out the location,” laughed our tester. However, it is not an issue once you figure out the cadence of the double click. Compared to some of Uniden's other detectors, the R7 is quite sizable. With that in mind, it didn't bother us as it is easy to remove from the window mount when not in use, and if placed low on the dash, it does not impede the driver's vision. Our main complaint is that the blind-spot monitoring filter leaves much to be desired. Generally speaking, this triggers a K-band alert, so turning the K-sensitivity down a notch helps mitigate the problem. This is a high-end radar and an excellent option for anyone looking to keep those pesky speeding tickets off their driving record. But if you'd rather enjoy auto lockout capabilities for a hands-free experience, the Escort Redline 360c is the one we recommend first and foremost.
The R7's range is great no matter what kind of terrain you find yourself on.

How We Test Radar Detectors
We strive to test our radar detectors objectively, ensuring that we consider everyone who might benefit from one. To kick off this category, we researched the best contenders on the market to narrow down our lineup to the top models available today for hands-on testing. From there, we took the time to understand how each detector works before testing them. Once we had familiarized ourselves with the capabilities and controls of each, we installed the devices and went looking for speed traps, photo-enforced red light cameras, and other radar-wielding law enforcement. We tested their accuracy by deciphering real from false alerts, determined their range of use, examined all their features, and assessed how easy each unit is to operate. We present an objective, in-depth review through research, unbiased observations, and personal experience.
Our comprehensive testing of radar detectors breaks down into four metrics:
Features (30% of overall score weighting)
Accuracy (25% weighting)
Range (25% weighting)
Ease of Use (20% weighting)

How to Choose the Best Radar Detector
A radar detector might be extraneous or essential depending on where — and how — you drive. (If you're reading this review, our guess is the latter case.) As with many pieces of specialized gear, there are a surprising number of things to consider. While our in-depth buying advice article dives deeper into these considerations and analyzes our test results to break down the nitty-gritty differences between these products, asking yourself a few key questions first can be helpful.
Are Radar Detectors Legal?
Even though this technology has been around for more than half a century, that doesn't mean it's widely accepted. While most states have walked back from their prohibition, radar detectors are still not legal in a few places in the US and much of Canada, and they are still prohibited in most commercial vehicles. Rather than listing them here, we highly suggest looking into the laws as they apply to the places and vehicles you drive.
How Is Your Driving?
Although many of us are guilty of chronically speeding, it's certainly not true for everyone. If you keep it relative to the speed limit, buying a radar detector is probably not even on your personal radar. But since you're here, the above question comes down to a cost-benefit analysis: how much money can a radar detector potentially save you? Weigh the price of a new radar detector — which can vary between $100 and $800 — against the cost of a speeding ticket, which tends to run around $150 at a minimum. If you invest in this technology, it's worthwhile to pay close attention to our Accuracy and Range metrics. A long-range detector, in particular, will give you enough time to slow down before law enforcement picks up your speed.
How Much Do You Want to Learn About Radar Detection?
These products range from highly automated to highly customizable. Depending on your interest in radar detection and your technological fluency, you may land on one side or the other. Our Ease of Use metric ranks the radar detectors we tested based on key user-friendliness aspects. As a primer, our buying advice article does a great job of breaking down available features. On the other side of that coin, our Features metric ranks these products according to their capability. It's interesting to note that the more features a radar detector boasts, the more expensive it will be. Equally interesting is that some of the most highly-featured models we tested were also some of the easiest to use.

Life is fast-paced, and we know it can be difficult to avoid putting the pedal to the metal when you're on the road. However, we often regret our heavy feet when the dreaded blue and red flashing lights hit our rearview mirror. Are you curious about how to avoid your next speeding ticket but don't know where to start? The market is flooded with radar detectors, and the price range is astounding. It can be hard to know what is worth the money and what isn't, which is why we are here to help. Knowing your technological skill level, driving style, and location is vital to a successful pairing.
What's the Best Value?
The devices we tested range from not-too-pricey to serious investment status, so finding the perfect combination of price and performance can be challenging. Comparing our scores to the price is a great place to start.
For excellent performance and a budget-friendly price, check out the Uniden R3. Its range is at the top of the pack, and accuracy is also stellar, other than MRCD. The Uniden R7 offers high performance at a mid-range price. It has a long range, making it good for highway driving.
Finally, if you're looking for the whole shebang and don't mind spending the extra money, the Uniden R8 and Escort Redline 360c are excellent detectors. The R8 is an updated version of the R7 with a longer range, better MRCD detection, WiFi, and a very fast response time. It is also highly customizable, so you have control over its performance in various locations. The Redline 360c is super streamlined, and it's perfect for someone who doesn't want to mess with the settings much but still wants a high-end radar detector.
As a relatively affordable unit, the Uniden R3 offers an unbeatable combination of range and accuracy for the price.

Features
What is a device without cool features, right? While accuracy and range are what we need from a radar detector, its available features set it apart from the rest. During our feature testing, we focused on four things: frequencies detected, sensitivity adjustments/modes, technology integration, and bonus features. Law enforcement uses a few different types of radar devices when scouting for speeders. There are red-light cameras, handheld radar guns, laser guns, and stationary speed traps. While many of these radars emit different frequencies, some pose a higher threat than others. An advanced radar detector will offer detection of X-band, K-band, Ka-band, laser, and MultaRadar frequencies. Many of the devices in our test suite offer detection of all the frequencies mentioned above, but some less expensive options lack MultaRadar detection. This is not necessarily a deal-breaker, but you will most likely need to upgrade to a device that does in the future because MultaRadar devices are becoming increasingly popular.
We love options as much as the next person, but too many alerts can muddy the waters. Keeping all five band detections mentioned above at their highest sensitivity will have your radar detector talking like it's gossip time at the water cooler. If we learned anything from “The Boy Who Cried Wolf,” we know that false alerts can cause desensitization when real threats are present. This is where the sensitivity adjustments and driving modes give you a leg up in the game. The ability to change the sensitivity of a particular frequency is huge. The X-band, for example, is so seldomly used that most people turn this detection off.
What Do the Different Alerts Mean?
X-band: Operating between 8.0 and 12.0 GHz, the X-band is an older band used mostly by automatic doors. If you receive this alert, it is most likely not law enforcement. You may want to turn this band off if your radar allows you to.
K-band: Operating between 24.05 and 24.25 GHz, the K-band is a somewhat popular frequency used by police radar guns today. If you receive this alert, take a look around, though it very well may be a false alarm. If you can turn the K-band sensitivity down, we suggest doing so.
Ka-band: Operating between 33.4 and 36.0 GHz, the Ka-band is the most popular frequency used by police today. If you receive this alert, SLOW DOWN! We recommend leaving this alert on at all times, as it is widely used.
MultaRadar(MRCD/MRCT): A frequency-modulated radar or a radar that oscillates between multiple frequencies. Many red light cameras are MultaRadar. If you receive this alert, it is most likely from law enforcement.
Laser: This is often used by higher law enforcement. If you receive this kind of alert, take it seriously.
The Uniden R8 has highly customizable features, including a new feature called Auto Mode. Similar to low-speed muting, it varies the sensitivity based on your traveling speed. Auto Mode differs from low-speed muting in that you actually have control over the baseline speed in which it operates. Once you've manually chosen your desired speed, the device will automatically kick itself into highway mode, amplifying sensitivity. On the flip side, if you are traveling under the designated speed, your device will default to city mode, reducing sensitivity to reduce false alerts.
Various sensitivity modes help keep the R8 quiet.

The Redline 360c, on the other hand, is highly automated. You have less control over the features and settings, but the presets work very well. The patented AutoLearn offers an intelligent GPS-based technology that learns your routes and rejects false alerts. The built-in WiFi allows for instant shared alerts and software updates, and the Defender Database offers advanced alerts for red light cameras and speed camera locations. The Defender Database is accessed through the Escort App, which is quite intuitive.

The Uniden R7 allows its users to adjust each band's sensitivity between 30% and 100%. You may also turn the detection of any frequency off completely. Advanced radar detectors also come with various modes that have preset sensitivities based on where you are driving or your user level. Highway mode, for example, is more sensitive than City mode, as there are more false alert triggers in cities. A runner-up in the features department is the Uniden R3. Similar to the R7 and R8, the R3 has city, advanced, and highway modes, GPS, and low-speed muting. You can also change the detector sensitivity for various signals.

The Escort MAX 360c offers a Novice mode that omits all the extra information and tells the driver to slow down if a threat is close. This is great if you struggle with technology or don't want to take the time to learn what every alert means.
What is the difference between the Escort MAX 360 and MAX 360c?
The MAX 360 and MAX 360c offer the same features, filtering, and performance capabilities. The main difference is that the 360c has built-in WiFi for automatic updates, whereas the 360 uses Bluetooth for cloud integration. There are some other subtle differences, like the body and the buttons, but as for the price difference, you are paying for the built-in WiFi and automatic updates.
Moving on to technology integration features. In the world of radars, technology refers to GPS, WiFi, and Bluetooth integration. Without GPS in the device or Bluetooth connecting the detector to your smartphone GPS, there is no way to manually lockout locations, gather speed limits, or offer information that requires your location. If you drive the same route often, manual lockouts are vital as you wouldn't want to continue hearing the beep of the automatic doors at the grocery store you pass on your way to work every morning. The Escort MAX 360c and Redline 360c take the location lockouts up a notch by offering auto lockout capabilities and real-time communication between drivers. The Uniden R8 also offers auto lockouts, but they do not perform nearly as well as the Escort models.
The Escort MAX 360 offers Highway/City modes and Novice/Expert modes.

As far as bonus features go, the Uniden R7, Escort MAX 360c, and Escort MAX 360 offer a plethora. The R7 has different sounds and colors for each alert, all customizable. This feature may seem small, but you don't want to be distracted by your radar detector while trying to avoid getting a speeding ticket, so you certainly do not want to be questioning what the device is telling you. Both Escort models also offer speeding alerts. You can pop into the app on your smartphone and adjust the settings to alert you when going a specific amount over the speed limit.

Accuracy
A radar detector that stays silent in the presence of radar gun-wielding law enforcement is money wasted. That being said, “accuracy” refers mostly to the device's ability to decipher between real and false threats. Alerts caused by non-threatening radar are called false alerts, and many things can set them off. Blind-spot monitoring systems (BSM) in modern cars, automatic doors at the grocery store, or train tracks are all culprits. There is no such thing as a perfect radar detector, but some certainly offer more accurate alerts with fewer false alarms.
The Redline 360c and Uniden R8 are extremely accurate. The 360c is accurate right out of the box, with a simple, only slightly adjustable system, while the R8 is more customizable, giving you complete control over your detector's responsiveness. The BSM filtering and MRDC detections on the R8 have been significantly improved from its previous iterations, but the automatic lockouts still malfunction often. The auto lockouts on the 360c, on the other hand, work great.
The Uniden R8 can pick up and portray up to five different bands simultaneously.

The Uniden R7 is also accurate. It picks up the appropriate signals, displays the correct direction of the threat, and falls quiet when the threat is no longer present. The only false alarm it seems to struggle with is blind-spot monitoring on neighboring cars. The presence of this type of radar often triggers a false K-band alert. Because the R7 is so highly adjustable in its sensitivity settings, it is not too difficult to turn down your K-band sensitivity to help filter out some of these BSM alerts.
Unfortunately the Uniden R7 struggles with blind-spot monitoring in neighboring cars which sometimes triggers a false K-band alert.

The Escort MAX 360c, MAX 360c, and Uniden R7 are all pretty accurate right out of the box. They easily pick up X, K, Ka, laser, and MultaRadar. Every device false alerts to some degree, so adjusting the settings to your desired sensitivity is essential. That said, if you fully understand what every alert means and are not bothered by the beeps and boops, you may want to leave sensitivity on everything up to have complete visibility into what is happening around you. The MAX 360 and 360c are connected to the Escort community via the cloud. This allows users to confirm that alerts were true threats, mark spots the device did not initially see, and deny threats so drivers can learn from each other's driving experiences.
Another notable for accuracy is the Uniden R3. The R3 struggles a little with BSM filtering and false alerts a little more than the R7 and R8, but for the price, it's a great value.

Range
Radar devices emit radio waves that bounce off the vehicle in question and get sent back to the device to read its speed. The radar guns used by law enforcement emit massive waves, so it is relatively easy for a detector to identify these waves before you can spot the source. This is a critical attribute because you need to be warned of the law enforcement officer before they can see you.
The Redline 360c takes the cake for long-range detectors, outperforming the competition. The triple antenna design (dual front and single rear) improves the range significantly. While testing this metric, we compared select detectors side-by-side to see which ones went off first, and the 360c was often the first to go off, regardless of the signal type.

Uniden is known for its long-range radars, and they don't disappoint. The R8, R7, and R3 prove to have some of the longest ranges, time and time again. Whether on a long straight highway, in a busy city, or driving through winding mountain roads, these models consistently picked up radar frequencies before their competitors. The R8 rocks an upgraded platform with a new dual LNA design, offering a slightly longer range than the R7 and R3. The upgraded condenser lens also improves range. The Escort models trailed a little behind. The MAX 360 and 360c lose out to the Uniden models every time, but they still offer ample time to slow down.

Ease of Use
Radar detectors are a great tool because even the most careful of us have been caught off guard going a few miles over the speed limit. However, these devices can be tricky if you don't understand how they work. In this category, we paid attention to the initial setup, ongoing changes to device settings, and overall visual and audible clarity.
Sometimes, a highly customizable device can lead to confusion and difficult navigation, but the Uniden R8 does a great job of walking that line. The menu is easy to navigate, and the controls are intuitive. Its features are easy to sift through on the device itself without having to pair it with an app. That being said, Uniden is working on an app for the R8, and we are excited to see what they come up with. Uniden also moved the mute and mark buttons from the side of the device to the front, which is a huge upgrade from the R7.
The mute and mark buttons on the R8 are very easy to click while driving.

The Redline 360c has a different approach than the R8. It's the perfect plug-and-go device. It has plenty of customizable features, but the presets work wonders, and the automatic lockouts give you a very hands-free experience.
The initial setup for these devices can include getting comfortable with the controls, downloading smartphone apps, and physically installing the device in your vehicle. Downloading and pairing the Escort MAX devices is a breeze. The app is also very informative, so making changes to the settings is just as easy. We did, however, have trouble hearing the alerts as the sounds were lost when the cab was particularly noisy.

Once you get used to the controls on the Uniden R7 and R3, they are both straightforward to navigate. Both detectors are also very audibly clear and easy to understand. The R7 has a very large multicolored OLED screen that makes it very visible. Unfortunately, the mute button on the side of the R7 can be difficult to reach in a pinch, making muting and manual lockouts a little difficult.
