Our Overview Course of for Radar Detectors
Automoblog is a member of the Radar Detector and Countermeasures Discussion board to make sure reality and accountability when protecting radar detectors. The Discussion board has members with years of expertise testing and validating radar detectors. These members can present further context and perception when you’ve got extra in-depth questions on a particular radar detector.
Whether or not we obtain a radar detector from a producer to evaluate or buy it with our personal cash, we contemplate 4 details. Hit the “present extra” arrow to see these factors. Our main driving areas with any new radar detector embrace the Detroit metro and the Ohio Turnpike.
Escort MAX 4 Overview: Fast Abstract
The MAX 4 is the entry-level unit in Escort’s MAX household of radar detectors, occupying the area as soon as held by the MAX 3. Though the MAX 3 remains to be out there (and for a decreased worth on Escort’s web site), the MAX 4 outpaces its older stablemate and punches above what its $400 retail worth would point out when it comes to vary and false alert filtering.
Noteworthy Options
Key options of the Escort MAX 4 embrace two Low Noise Amplifiers (LNAs), a dual-core processor, an IVT filter, and a multi-color OLED show.
The MAX 4 is appropriate with the Driver Smarter app, which sends user-generated police radar alerts to your telephone for superior warnings (extra on the app beneath, together with its compatibility with Mapbox, Apple CarPlay, and Android Auto).
The Escort MAX 4 has a single, front-facing antenna, which differs from different higher-tier radar detectors that make the most of a dual-antenna design. Directional arrows, which illuminate on the show, are among the many main advantages of a dual-antenna radar detector. Radar detectors with directional arrows (aka directional alert arrows) present extra situational consciousness as you’ll be able to verify whether or not the radar supply is forward of or behind you.
Against this, radar detectors with a single, front-facing antenna, just like the Escort MAX 4, can nonetheless detect police radar however can not decipher which course it’s coming from.
Reasonably priced, Not Low-cost
Based mostly on our expertise, the Escort MAX 4 is an efficient choice if you’re trying to buy your first radar detector or if you wish to improve from one thing older however don’t need to spend an excessive amount of.
Its affordability is a far cry from low cost, because the MAX 4 provides a dose of the newest tech to be purposeful and sensible to your every day drive with out having to dip too far into your checking account.
What We Will Cowl
Our focus right here is to undergo the Escort MAX 4 that will help you determine if it’s the correct radar detector for you. We’ll look “beneath the hood” of the unit, spotlight the principle options, and stroll via the settings menu. Alongside the way in which, we are going to share our expertise utilizing the MAX 4 round Detroit and on an prolonged highway journey to Cincinnati.
We’ll start with a fast however complete overview of Escort radar detectors, which offers you an concept of how they design their merchandise, together with the MAX 4.
Escort Radar Detectors: Focus On The “Falses”
As a model and producer of radar detectors, Escort has made its title on its potential to filter out “the noise” of your every day drive. Whereas no radar detector, together with an Escort detector, is proof against false alerts, Escort makes a substantial and concentrated effort to maintain false alerts to a minimal.
Radar-Based mostly Security Techniques
Among the many challenges for radar detector producers at the moment is the sheer variety of radar frequencies in any given space. Computerized doorways are nonetheless a thorn within the aspect, and when you’ve got owned a radar detector prior to now 20 years, you’ll be able to attest to that.
Along with the native purchasing plaza, radar detector producers should cope with an growing variety of late-model autos on the highway at the moment with security programs that leverage radar sensing. These programs can embrace however are usually not restricted to, collision avoidance programs, blind-spot displays, and hands-free programs like Ford BlueCruise and GM’s Tremendous Cruise.
Including to that problem is how, in contrast to a set of stationary automated doorways, all of those late-model autos with their radar-inspired security programs are transferring about. The speculation is that with out correct filtering (aka false alert filtering), a radar detector would continually alert as you drive in visitors. If that have been the case, how lengthy wouldn’t it be earlier than you’re taking the detector down out of your windshield, and would you ever be inclined to buy one other one?
Alert, Not Annoy
When designing its MAX household of radar detectors, Escort labored beneath the mindset that buyers should be alerted, not aggravated, by a radar detector.
Escort’s engineering and improvement groups recall their very own tales of how, lengthy earlier than working for Escort, they bought a radar detector on a whim, solely to “throw it again within the field” as a result of the false alerts and fixed beeping have been insupportable.
As we transfer up in Escort’s MAX household, the extent of false alert filtering turns into extra pronounced. For instance, the MAX 360 MKII and MAX 360c MKII use the Blackfin DSP (digital sign processing) chip from Analog Units, which makes them two of the quietest radar detectors at the moment. The Blackfin is a key characteristic in different high-end Escort choices, just like the MAXcam 360c and Redline 360c.
Basically, the upper you go in Escort’s product lineup, the larger the diploma of false alert filtering.
Escort MAX 4 In-Depth: What It Provides
The MAX 4 comes with a 12V energy wire, a suction cup windshield mount (referred to as an “EZ Magazine Mount”), a carrying case, and a fast begin information (you’ll be able to obtain the entire proprietor’s handbook from Escort’s web site).
The 12V energy wire has a USB port on the bottom, so you’ll be able to nonetheless cost your telephone. It’s a pleasant characteristic in case your automobile doesn’t have a wi-fi charging pad.
Low Noise Amplifiers (LNAs) & Twin-Core Processor
The MAX 4 has two Low Noise Amplifiers (LNAs) and a dual-core processor, complementary options concerning vary detection and false alert filtering.
As defined in this peer-reviewed journal article from Science Direct, the LNA will enhance the acquired sign (radar within the case of the Escort MAX 4) to a ample degree above the noise flooring so it may be used for added processing (dealt with by the dual-core processor on this occasion).
Sign-to-Noise Ratio
A technique to think about the LNAs of the Escort MAX 4 is to think about we’re recording an interview in a room with plenty of further background noise. There may be an occasion taking place with a lot of individuals, or we may very well be exterior with ambient noise of wind or vehicles passing by.
As soon as we now have that audio recording, we are going to need to apply some post-production, say with a program like Adobe Audition. Ideally, we need to reduce the background noise to attract extra consideration to the individual we interviewed. This is a primary means to think about signal-to-noise ratio, whereas the audio of the individual is extra vital than the background noise.
Solely Enhance What Is Fascinating
Taking {that a} step additional, if we “enhance” the audio degree of the individual we now have simply interviewed in post-production, the entire background noise is concurrently boosted.
To eradicate or scale back that undesirable background noise and amplify simply the audio of the individual we’re interviewing, we would want to use noise discount filters via a program like Adobe Audition. Finally, the background noise can be lower (or strongly decreased), permitting the interview audio to return via extra cleanly.
It’s the same idea right here with the Escort MAX 4. When the MAX 4 detects a radar sign, the LNAs amplify it above the background noise so it’s intelligible sufficient for the dual-core processor to research. The twin-core processor determines if that radar supply is fake or authentic, and if it’s the latter, relays that data to the show display to provide you with a warning.
In case you have the MAX 4 set to “Spec” within the settings menu, you will notice the radar band kind, sign energy, and numeric frequency.
Vary Detection & False Alert Filtering
LNAs are a characteristic in different inexpensive however high-performing radar detectors, like the Uniden R4, arguably the MAX 4’s greatest competitor.
Just like the age-old Ford and Chevy debate, radar detector lovers may have a lot to debate when evaluating the deserves of the Uniden R4 and Escort MAX 4. Whereas our official place is that they’re each nice radar detectors, one factor is for positive: the MAX 4, with its twin LNAs and dual-core processor, has higher detection vary and false alert filtering than the MAX 3.
Our analysis of the MAX 4 consisted of a late afternoon drive down I-75 from Detroit to Cincinnati. A number of areas alongside the way in which, principally highway development zones in and round Dayton, Ohio, triggered some short-term and fleeting false Okay band alerts. In any other case, via Cincinnati and round Detroit, and for many of the drive down I-75 and again residence, the MAX 4 was quiet within the Auto Lo Okay sensitivity mode.
Coming again residence from Cincinnati, the Michigan State Police have been patrolling closely simply previous Toledo, notably the stretch of I-75 between Monroe and Flat Rock, Michigan. On two events, the Drive Smarter app (coated additional beneath) offered us with user-generated warnings so far as 4,000 ft away (roughly 0.75 miles). The MAX 4 would alert shortly thereafter, normally from a couple of half mile out.
The longest detection vary we noticed was 0.9 miles on Jefferson Avenue, heading into Detroit from Grosse Pointe. Stopped on the intersection of Walker Avenue and Jefferson Avenue, the MAX 4 alerted to a 34.7 GHz Ka band. We continued to comply with the sign till we handed a Detroit Police automotive that had stopped one other automobile in entrance of the Meijer Rivertown Market.
The screenshots beneath from Google Maps present our approximate location on the intersection of Jefferson Avenue and Walker Avenue and the placement of the Meijer Rivertown Market, the place the Detroit Police stopped a motorist.
Band Detection: Ka, lidar, Mesta Fusion
The MAX 4 will provide you with a warning to X, Okay, and Ka radar bands and laser (lidar) weapons. Likewise, the unit detects MultaRadar CD and CT, typically written as MRCD and MRCT for brief. MultaRadar is normally related to visitors mild cameras and different photograph enforcement gadgets.
In contrast to a typical radar gun with steady wave radar that transmits on a set frequency, MultaRadar adjustments frequency, making it tougher to catch, particularly for older radar detectors (that is identified as frequency-modulated radar). To make use of a board sport analogy, MultaRadar is all the time “rolling the cube” and touchdown on a special quantity, whereas the steady wave radar cube will land on the identical numbers.
Newer radar detectors, just like the Escort MAX 4, can provide you with a warning to MultaRadar. The default settings for MRCD and MRCT are off, however each will be switched on within the settings menu beneath the “Band Allows” tab or by way of your telephone when linked to the Driver Smarter app.
Likewise, the MAX 4 additionally detects Mesta Fusion, a long-range, multi-lane, and multi-target enforcement technique equipped by French know-how firm IDEMIA. Mesta Fusion towers, which mix a Doppler radar and high-resolution digicam, have been deployed in Edmonton, Alberta, Canada, after metropolis officers acquired an indication from IDEMIA in 2017.
The Radar Detector and Countermeasures Discussion board maintains a database of photograph radar programs, together with member-supplied pictures of what these programs appear to be.
Sensitivity Modes
The Escort MAX 4 provides 4 sensitivity modes: Freeway, Auto, Auto No X, and Auto Lo Okay, the latter being our desire right here in Detroit. Here’s a fast overview of every mode.
Freeway
Freeway means most sensitivity throughout the board, with all radar bands (X, Okay, and Ka) at their fullest sensitivity. Okay band is price noting right here as a result of its sensitivity is at its most, which is totally different from a mode like Auto Lo Okay.
We use Freeway right here in Michigan, however solely because the title suggests: on the open highway, as band sensitivity ramps up in accordance along with your pace. On an open expanse of interstate, you need probably the most response time if/when police radar is current, which Freeway mode permits.
One smaller Downriver group south of Detroit makes use of Okay band, so Freeway mode will be useful after we journey to Toledo, Ohio, on that a part of I-75. Freeway mode’s further Okay band sensitivity can alert to these patrol autos higher than different sensitivity modes.
Auto
Auto is handy because it reduces X and Okay band sensitivity based on your pace.
As a speed-dependent mode with robust “set it and neglect vibes,” Auto sensitivity is just like the well-known burgers your favourite joint is thought for. They’re staples on the menu as a result of you’ll be able to by no means go mistaken ordering them. Auto sensitivity for the MAX 4, or any Escort radar detector, is identical. When unsure, go for Auto!
Auto No X
Auto No X is speed-dependant just like the Auto sensitivity mode, however it shuts down X band detection. Since X bands are normally false, Auto No X retains the MAX 4 from alerting to them.
Auto Lo Okay
Auto Lo Okay is our private favourite. Like the usual Auto sensitivity mode, it’s nonetheless speed-dependent, though it differs in that Okay band sensitivity is saved to a minimal always. In consequence, Auto Lo Okay is arguably the quietest of all of the sensitivity modes on the MAX 4.
Segmentation Choices
Beneath the “Band Allows” tab within the settings menu or via the Driver Smarter app, you’ll be able to experiment with 4 totally different Okay Slim and 10 Ka Slim segmentation choices or “customized sweeps” to dial within the MAX 4’s response time.
Flip both Okay or Ka Band detection off to activate the segmentation choices (executed both via the settings menu or the Drive Smarter app). This allows the “selectors,” which additionally, you will see within the settings menu or the Driver Smarter app.
Though it appears counterintuitive, turning off Ka band detection doesn’t imply you might be leaving your self uncovered to the commonest type of police radar. It merely means now you can work with the segmentation filters.
After we deactivate the Ka bands, Escort’s manufacturing unit default Ka Slim settings take over, permitting our MAX 4 to scan from 33.700 to 35.600 GHz. That aligns with legislation enforcement radar weapons, not simply right here in Michigan, however all correctly and legally tuned U.S.-spec police radar weapons.
Out of the ten out there Ka Slim settings, the MAX 4 may have 2, 5, and eight turned on by default. It breaks down like this:
- KA Slim 2: 33.700 to 33.900 GHz
- KA Slim 5: 34.600 to 34.800 GHz
- KA Slim 8: 35.400 to 36.600 GHz
The thought behind band segmentation is to think about wanting via a row of home windows. It takes much less time to look via three home windows than 10, and the thought right here is analogous with band segmentation. A radar detector working in a slender segmentation versus a wider setting will alert faster as a result of it’s not scanning or “watching” your entire out there frequency vary.
AutoLearn Expertise (Auto Lockouts)
AutoLearn analyzes fixed-location radar over time to find out whether or not such alerts are authentic or false. Ought to the MAX 4 encounter the precise frequency in the identical location roughly 3 times—and that frequency is deemed false—it routinely locks it out and flashes a “Saved” message. The MAX 4 makes use of Escort’s TrueLock GPS Filter to lock out and retailer fixed-location false alerts in its reminiscence financial institution.
Escort’s AutoLearn characteristic has turn out to be synonymous with its MAX household of radar detectors, and it may be a handy device whereas driving. It’s price noting, nonetheless, that some fixed-location radar sources, like automated doorways, could have some variance. For instance, seasonal temperature adjustments can have an effect on the frequency these radar sources transmit and should impression the AutoLearn characteristic.
Faucet the Mute button on the 12V energy wire to manually lock out a false alert. When encountering a beforehand locked-out location, it’ll show in grey however not audibly alert.
Mark Areas
The MRK button on prime of the unit will flag a location after which notify you the subsequent time you might be about to cross it. In contrast to the lockouts (handbook or automated), the Mark Location characteristic is meant for areas with authentic threats.
When marking a location for the primary time with the Escort MAX 4, you’ll be able to specify what it’s, from pink mild and pace cameras to hurry traps. You even have an “different” choice to mark a location for an additional purpose.
IVT & Okay Notch Filters
Escort’s proprietary IVT Filter, or “in-vehicle know-how” filter, is constructed into the MAX 4. The IVT Filter decreases the variety of false alerts brought on by collision avoidance and adaptive cruise management programs of different autos, that are radar-based.
The Okay Notch filter will be activated within the settings menu for a similar purpose, lowering false alerts brought on by sure vehicles and their radar-based collision avoidance programs (between the frequency ranges of 24.190 and 24.210 GHz). We now have the Okay Notch filter on right here in Detroit.
Drive Smarter App
Escort has significantly improved the Drive Smarter app for the MAX household of radar detectors (Drive Smarter is the alternative for Escort Stay).
When linked to Drive Smarter, your telephone will obtain real-time risk notifications in your space, be it a radar supply, pink mild digicam, pace digicam, or police patrol, as reported by different Escort homeowners utilizing the app (i.e., shared alerts).
Likewise, you’ll be able to challenge an alert for others by way of the app in case you discover one thing like a pace entice or stationary patrol automotive or encounter a pace entice, visitors jam, highway development zone, or different highway hazard.
Along with sending and receiving alerts, Drive Smarter helps you to regulate a bunch of settings for the MAX 4 out of your telephone, together with show colours and brightness, sensitivity modes, and extra.
Connectivity & Crashing Points
Up to now, we skilled Bluetooth connection and crashing points between the app, the detector, and our Motorolla telephone with an Android-based working system. Nevertheless, Escort has continued to refine its efficiency, particularly for Android working programs.
Buyer Service
Whereas engaged on this Escort MAX 4 evaluate, we chatted with customer support reps over e-mail from Cedar Electronics (you’ll be able to contact a assist rep via the Drive Smarter app). The reps we exchanged e-mails with about our points have been skilled and courteous in every occasion.
As of early 2024, the entire connection and crashing points we had with Drive Smarter have been resolved, together with minor glitches like how the pace restrict in a given space may show as 74 mph on the app when it’s truly 75 mph.
Even with these fixes and enhancements, Escort reps inform us they’re persevering with to refine the general efficiency of the Drive Smarter app for his or her clients.
Apple CarPlay, Android Auto & Mapbox
The revised Drive Smarter app is appropriate with Apple CarPlay and Android Auto and has Mapbox built-in.
In your automobile’s touchscreen, you will notice the entire regular Apple CarPlay or Android Auto options alongside any real-time risk notifications from Drive Smarter. Equally, Escort has added Mapbox performance, which means Drive Smarter successfully doubles as a navigation app.
Whereas Drive Smarter is non-compulsory and never vital for the MAX 4 to detect police radar, operating it may improve situational consciousness. When paired with the MAX 4, we discovered that Drive Smarter, on some events, will notify us of police radar sources earlier than the detector points an alert. This superior discover is useful, particularly in a busy space with heavy visitors.
In case your automobile has a wi-fi charging pad, use that to assist save your telephone battery whereas operating Drive Smarter.
Is The Escort MAX 4 Price The Cash?
The Escort MAX 4 is among the finest radar detectors within the $400 worth vary. It’s an inexpensive choice that gives good vary detection and glorious false alert filtering by combining a pair of Low Noise Amplifiers with a dual-core processor. The Drive Smarter app offers an added layer of safety and will increase the general performance of the Escort MAX 4.
For the reason that MAX 4 was launched in late April 2024, it was not included in our earlier roundup of the finest radar detectors of 2024, which was revealed earlier this yr. Nevertheless, that record offers a couple of different choices throughout all totally different worth factors and producers if you’re not offered on the MAX 4.
When you determine to buy a MAX 4, regulate Escort’s web site for the newest firmware updates. Likewise, in case you get a brand new MAX 4 and have questions, be part of us on the discussion board, and we are able to level you in the correct course.

Radar Detectors FAQ
Are Radar Detectors Authorized?
Utilizing a radar detector in a privately owned passenger automobile is authorized within the U.S., excluding Virginia and Washington D.C. Radar detectors are unlawful in business autos. See this information to radar detector legal guidelines for all 50 U.S. states when you’ve got further questions.
How Do Radar Detectors Work?
Whereas proprietary know-how can differ between every radar detector producer, consider a typical radar detector when it comes to receiving and deciphering.
Each radar detector has a “horn” or antenna (generally multiple) and an inner microprocessor. The antenna picks up or receives the police radar gun, and the microprocessor deciphers it, finally exhibiting on the show display vital data like sign energy and band kind.
Radar detector producers construct on that primary precept with their very own {hardware} and software program to realize elevated detection vary with fewer false alerts.
Will My Radar Detector Alert to Laser Weapons?
Sure, all radar detectors will alert to police laser weapons, which means your radar detector can be a laser detector by default.
Some radar detectors are appropriate with an adjunct referred to as laser shifters, however these are totally different from laser jammers, that are unlawful in some states. Police laser weapons use a know-how referred to as lidar, which stands for mild detection and ranging.
What Is The Finest Radar Detector For Me?
The most effective radar detector for you’ll rely upon the place and the way you drive and the way a lot you need to spend.
When you love having the newest and best devices, you may benefit from the encompasses a high-end unit will present. Against this, in case you solely want a mild reminder of police radar within the space, you could find one thing extra primary however nonetheless of fine high quality.
Standard radar detector producers at the moment embrace Cobra, Escort, Radenso, Uniden, Valentine, and Whistler. Some high-performance radar detectors, just like the Escort Redline 360c, are appropriate with a smartphone app that shares user-generated alerts.
I Noticed a Police Automobile, Why Didn’t My Radar Detector Alert?
Typically, a patrol automotive may have its radar gun off, which means there may be nothing for the radar detector to alert to. Visitors officers additionally use an enforcement technique referred to as “Immediate-On” radar, the place they solely use their radar gun at sure instances (assume just like the storied picture of the officer on the motorbike hiding behind the billboard).
If this occurs, visitors officers will solely goal one automobile at a time. Most high-quality radar detectors will alert to Immediate-On radar with loads of superior discover, though it’s nonetheless attainable to get a ticket by way of Immediate-On if you’re not cautious.
