Best Radar Detectors of 2023: Crash Course

• The Escort MAX 360 MKII, Uniden R8, and Cobra RAD 700i are among the best radar detectors in 2023.
• Some of the best radar detectors are more affordable than you might think.
• Where you live and how you drive will determine which radar detector is right for you.

The best radar detectors offer long-range detection, solid False Alert Filtering, and a seamless user experience while helping you avoid a speeding ticket. Radar detectors can sometimes be a “you get what you pay for” type of purchase. However, try not to confuse that with a “go big or go home” approach, as there are still good options that won’t break the bank.

Below, you will find helpful information on the best radar detectors today, including the advantages and drawbacks of each unit, along with a quick overview of its features.

All the radar detectors here will alert you to X, K, and Ka radar bands, laser guns (or lidar), and MultaRadar CD and CT, written as MRCD and MRCT for short. MultaRadar is often associated with traffic light cameras and other photo enforcement devices.

We own every radar detector listed below and will share our experiences with each. Near the end, we include a brief section on picking the best radar detector for your needs and budget.

Best Radar Detectors: 2023 List

In the table below, you’ll find our list of the best radar detectors of 2023.

Uniden R8 Review Scores

Uniden R8 Pros & Cons

Uniden R8: Our Experience

The Uniden R8 makes our best radar detectors list because of its long detection range and features that increase situational awareness, like directional alert arrows and the All Threat display. Meanwhile, the Auto sensitivity mode is practical for everyday driving.

Detection Range

This is where all Uniden radar detectors shine, and the R8 is the best in Uniden’s family. If you frequently drive on interstates like I-70, I-80, I-5, or any other road with miles and miles of concrete ahead of you, the R8 is your best friend. On long stretches of road, our R8 has given us at least a mile’s notice, if not more, when a patrol vehicle is ahead.

Twice a year, we drive to Minneapolis from Detroit for a business trip, which gives us time to evaluate products like radar detectors. Our route takes us west across Michigan on I-94, through Chicago, and then up through Wisconsin on I-90 on the way to Minnesota. It’s on these open expanses of road that we appreciate the Uniden R8’s long detection range.

On these longer trips, we run our Uniden R8 in Highway mode, in which the detection of all major radar bands (X, K, Ka, and Laser) goes to full sensitivly. In essence, the R8 can “hear a pin drop” when it comes to detecting police radar on the open road.

All Threat & Auto Sensitivity Mode

With the All Threat feature turned on via the settings menu, the R8 will simultaneously detect up to four radar bands, showing each of them visually on the OLED display. The strongest signal is designated as the priority and will appear front and center, like in the photo above.

Up to three other signals can appear on the left side of the screen in what resembles a little digital chart. This digital chart shows the individual radar band, its signal strength, and direction. The advantage here is how the Uniden R8 alerts you to multiple police radar sources in the same area at the same time.

Although we use the Highway sensitivity mode for longer trips, in and around the Detroit metro, we opt for Auto sensitivity. It’s a speed-dependent mode, automatically switching back and forth between City and Highway modes at a pre-set speed (you can set that speed in five mph increments between 10 and 60 mph in the settings menu).

Cobra RAD 700i: Best Budget Option

The Cobra RAD 700i hits that sweet spot between performance and price, making it an excellent choice if you want to purchase your first radar detector or upgrade from an older unit. As the latest in Cobra’s RAD family of radar detectors, the 700i easily outpaces the older 480i and 380.

Perhaps more importantly, the RAD 700i gives other higher-priced radar detectors on this list, like the Uniden R4 and Radenso DS1, a run for the money.

Cobra RAD 700i Pros & Cons

Cobra RAD 700i: Our Experience & Escort Comparison

Under Cedar Electronics are two popular manufacturers of radar detectors: Cobra Electronics and Escort Radar. And under each of those is a “family” of radar detectors: RAD (Cobra) and MAX (Escort). Cobra is the more budget-focused brand, while Escort is the premium nameplate.

Cobra’s RAD family doesn’t have the same performance muscle, robust material construction, or detailed feature set as Escort’s MAX family, but the price point is much more affordable.

As Cobra and Escort are under Cedar Electronics, they share some similar features, like compatibility with the Drive Smarter app outlined above, but otherwise, there is a clear divide between the two product lines. The Cobra RAD 700i, however, closes that gap in some key areas, offering a near Escort level of performance for a fraction of the cost.

For example, the RAD 700i borrows certain technical aspects from Escort’s MAX family, like digital signal processing for better false alert filtering (DSP for short).

False Alert Filtering

While the RAD 700i does not have the same level of DSP integration as the MAX 360 MKII, our top pick, it still punches above what its $250 retail price would suggest. In our experience, the RAD 700i has better false alert filtering than the Uniden R4 and Radenso DS1, both of which are on this best radar detectors list, and both of which are more expensive than the RAD 700i.

Through metro Detroit and across the Ohio Turnpike en route to Sandusky on two occasions in the summer of 2023, the RAD 700i didn’t flinch when passing common false alert sources like digital road signage. Much to our continued surprise, the RAD 700i stays quiet when driving past most shopping plazas (automatic doors can trigger a false alert for most radar detectors).

Additional false alert filtering comes from Cobra’s proprietary IVT Filter, or “in-vehicle technology” filter. The IVT Filter decreases the number of false alerts caused by collision avoidance and adaptive cruise control systems of other vehicles, which are radar-based.

Uniden R4: Best For Smaller Towns

Just as the R8 on this list was the successor to the R7, the Uniden R4 is the follow-up to the trusty Uniden R3. As such, the newer R4 has advantages over the R3 when it comes to detection range, false alert filtering, and available features. In so many words, the Uniden R4 takes everything good about the Uniden R3 and turns it up a notch.

For quick trips around the suburbs of Detroit or any smaller towns in Michigan, we usually reach for our R4.

Uniden R4 Pros & Cons

Uniden R4: Why We Like It For Smaller Towns

While the Uniden R4’s older brother, the R8, is our preferred choice for highway driving, the R4 is our top pick for driving around the suburbs of Detroit or any smaller community. In these areas, we can live without some of the features offered by more expensive radar detectors.

Directional Arrows & Smartphone Apps

The Drive Smarter app for Escort and Cobra radar detectors is great in metro Detroit, where there are apt to be more users in the area generating real-time alerts. By contrast, when we drive in less populated places, there are, by nature, fewer users on the app. It’s not that the app is worthless in smaller towns, but its value isn’t the same as being in a big city.

It’s similar with directional alert arrows. Indeed, they have their benefits, but it’s a feature reserved for more expensive radar detectors. In a larger metropolitan area, they are helpful in heavy traffic when you can only see so far ahead or behind you. However, if you live in a smaller community, chances are you know where the local police sit most of the time (bank parking lot, near the grain elevator, high school baseball field, and so on).

If that’s the case where you live, you really only need a notification that the officer is sitting there and not necessarily if they are ahead of you or behind you. That said, even though the Uniden R4 doesn’t have directional arrows, it may not matter in a small town.

The Right Balance

If your primary driving takes place in a smaller town, consider the Uniden R4. While you won’t have directional alert arrows like the R8 or a smartphone app like Escort and Cobra offer, you will have the right balance of performance for the price. In other words, with the R4, you won’t be “overbuying” when it comes to having the best radar detector for where you live.

And for those longer trips on the highways outside of town, the R4 can easily handle the job. The Auto sensitivity mode will make it convenient, adjusting between City and Highway modes automatically based on your speed.

Radenso DS1: Easiest To Use

The Radenso DS1 is a straightforward radar detector with a multi-color OLED display, auto lockout capability, red light and speed camera alerts, and long-range Ka band detection.

We like how the DS1 prioritizes a simple and streamlined user experience without totally sacrificing performance and reliability. In terms of performance, our biggest critique of the Radenso DS1 is an unexpectedly high number of K band false alarms.

Radenso DS1 Pros & Cons

Radenso DS1: Our Experience

Like the Uniden R4 above, the DS1 is an excellent “grab and go” radar detector because of its simplicity. It’s another solid choice if you live in a smaller community, but its feature set can handle larger areas, like where we live in Detroit.

In either environment, the DS1 needs minimal setup in order to be effective. While you can experiment later with different segmentation filters, display colors, and alert tones, we like how the DS1 is ready to go right out of the box.

Auto Sensitivity & Threat Display

In Detroit, on roads like M10, I-696, I-94, and Telegraph Road, traffic tends to fluctuate. One moment you are poking along, and the next, you are back up to highway speeds. For these occasions, we like the DS1’s Auto Sensitivity feature. When our speed exceeds 50 mph, Highway mode kicks in automatically, and for anything under 50 mph, the DS1 defaults to City.

The DS1 can simultaneously show up to three radar bands, prioritizing laser and MRCD, followed by Ka, K, and X. Prioritized threats appear front and center, with the other alerts showing in a smaller font (with an accompanying bogey tone) on the left portion of the OLED display.

False Alert Filtering

Ease of use is one of the strongest selling points of the Radenso DS1, but the false alert filtering could stand to improve. On this list of best radar detectors, the DS1 struggles the most with false alert filtering.

To be fair, any radar detector, even top-of-the-line ones, will have the occasional false alert; no radar detector is immune. However, when false alerts interrupt your driving and interject themselves into a conversation with your passenger, that’s a different story.

Driving past a CVS or Kroger tends to whip our DS1 into a frenzy of K band false alerts. On the interstate, nearly every road construction zone or digital sign will cause the DS1 to false.

This experience with the DS1 is discouraging, given its retail price and how well it delivers in other key areas like Ka detection range, ease of use, and even additional customization options via the settings menu.

Escort MAXcam 360c: Best Combo Unit

The MAXcam 360c is an enhanced version of the Escort MAX 360c radar detector with a 1440p dash camera. As a two-in-one, tech-packed unit, it’s the most expensive on this list, but some may find the dual functionality has its advantages.

The little “c” in the name stands for connected, meaning the MAXcam 360c can connect to Wi-Fi to receive the latest firmware updates (versus a hardwired connection via your laptop). If you run the Drive Smarter app with the MAXcam 360c, you can pair the two via Bluetooth or a Wi-Fi hotspot.

Escort MAXcam 360c Pros & Cons

Escort MAXcam 360c: Our Experience

If you want to consolidate your radar detectors and dash cams into one portable unit, the Escort MAXcam 360c is the best choice on the market.

The Cobra Road Scout is similar, offering a radar detector and a dash camera, but our feelings are still mixed at best with the Road Scout. Based on our experience, the MAXcam is a better option.

Escort MAXcam 360c Radar Detector

The radar detector portion includes Escort hallmarks like front and rear antennas, directional arrows, and AutoLearn Intelligence, which automatically locks out false fixed-location alerts.

Like the MAX 360 MKII, our top pick on this list, the MAXcam also includes the Blackfin DSP for exceptional false alert filtering, plus two additional and convenient sensitivity modes in Auto No X and Auto Lo K.

We drive in Auto Lo K most of the time, which minimizes the instances of K band falses. The Escort Redline 360c is still the best for range detection, thanks to its triple antenna (two front, one rear) design, but the MAXcam 360c can hold its own. We have no complaints about the MAXcam’s range detection or false alert filtering capabilities.
