How to Hardwire a Radar Detector the Easy Way

Radar detectors are used by drivers to avoid being tracked down for over speeding. It uses a Superheterodyne technology-driven receiver in detecting electromagnetic emissions from radar guns.

The same device raises an alarm to notify the driver each time a transmission is detected. For whatever purpose there is, learning how to hardwire a radar detector might come in handy someday. 

However, false alarms are inevitable due to a large number of devices, such as automatic door openers—which are often found in malls or supermarkets, speed signs, and adaptive automotive cruise control that operate in the same parts of the electromagnetic spectrum as that of radar guns.

Why Learn How to Hardwire a Radar Detector?

It is a must that a radar detector is hardwired to a car. Usually, it is plugged-in for power or is powered up by a cigarette lighter's plug—experienced drivers will understand.

Such are easy ways to power the detector. However, the long dangling cable down the windshield is quite distractive to the driver and can even block the way of the stereo.

Sometimes, car owners take down their radar detectors when parked for less visibility. One alternative that can be done is hardwiring the radar detector. Simply put, this is the process of creating a plug dedicated to only the radar detector, instead of sharing with the lighter outlet.

Instead of taking up the cigarette lighter outlet, there is a better and more doable option. You can try to power up the detector through a car’s fuse box by running a hidden power cable along the vehicle's trim. This also gives it a more professional and cleaner installation.

When you mount the detector near the headliner, not only it does look better, but it also gives better detection of the radar.  This way it is also less visible to potential thieves or police—it can be left in your car because it has now a lower risk of being seen.

Hardwiring radar detectors can be a hassle to some car owners. You can opt to hire a pro to do it for you. It won’t take much of your time and money.

But if you are down for it, we have a step by step guide on how to hardwire a radar detector on your own. It is also the preferred method to power up the radar.

Things you will need:

  • Hardwire cable
  • Add-a-circuit fuse tap kit
  • T-tap (this is optional)

Hardwire Cable

There are different types of cable that can be used. For this one, you will need a hardwire cable or direct cable—it is a straight and long cable which connects a source of power to the radar detector. What most people usually use is the traditional or regular hardwire cable.

There are some which add in an additional mute remote button and alert LED. Others would add Bluetooth to pair the detector with a phone and other things you can do with it.

Add-a-circuit Fuse Tap

Within your car, you’ll find lots of fuses for the different car parts: Air Condition, power seats, stereo, airbags, etc.—which is why the fuse box can be placed in various locations in different cars.

You will be adding the radar detector, so it is also tapping into the fuse box like all the other electronics. An add-a-circuit is needed to tap it in the fuse box.

The add-a-circuit allows you to place new electronics to an existing fuse box. Manufacturers utilize different fuse sizes so you’ll have to choose the right one for your car. After figuring out the fuse size, an add-a-circuit kit is to be picked up.

You are able to get the kits of the most known fuse sizes from Micro2 add-a-circuit kit, Low-profile mini add-a-circuit kit, Mini-add-a-circuit kit, and ATO add-a-circuit kit. All these include the add-a-circuit kit and some extra fuses needed for the new devices you’re adding.

Hardwiring 101:

Plug in the Add-A-Circuit.

Find a fuse box that turns off and on with the car’s ignition—mostly, a couple of circuits are powered all the time while the others are tied down to the ignition. Utilize something that also switches off when you turn off the car so that the radar detector doesn’t drain.

When you start up your car, the detector turns back on. Note that you’ll also have to poke around since it varies with every car.

Check your car’s manual

Check your car’s manual to see what each fuse is for. After finding out which fuse you will use, pull the existing fuse out using a fuse puller or pliers. Once you pulled it, put the fuse in the add-a-circuit that has slots for two fuses.

Connecting the Add-A-Circuit.

There are two main ways to add your hardwire cable after installing the add-a-circuit to your fuse box; The first one is by connecting the blue switch to the add-a-circuit end.

That is also when stripping the hardwire cable's power wire end can be done, in case it isn't stripped yet. You can then place it into the blue connector.

Pro tip: To make a nice solid connection, you can use a crimper or a T-tap on the blue connector.  

Connecting your Ground Wire.

Power and ground make up your hardwire cable. You get power from the add-a-circuit, and you’ll have to connect the ground somewhere else.

Ground wires can be found from some existing electronics and just tap into it, or connect it to a part of your car’s chassis that is metal. 

Running the Wires.

After the hardwire cable is connected to the ground and add-a-circuit, simply plug in everything and run the wires. From your fuse box, you may run the wires and then up your A-pillar.

From there, drag the wire across the headliner, and then into your radar detector. You may also just try to push the wires behind the body panels, although you will need to remove the panels to get a clean installation. 

Again, if the installation is a hassle for you, you can always ask a professional to do these steps. Once these steps are done, you are good to go with your newly hardwired radar detector.

Scanning for the Best Radar Detector Brands

Scanning for the Best Radar Detector Brands

Time is as valuable as bitcoin or gold, especially during our modern times where almost everybody works more than 40 hours per week just to make ends meet.

Spending time for trial proceedings in a traffic or small claims court takes away considerable hours from this valuable time, and speeding seems to be one of the top violations being heard. One innovative way of getting around speeding violations—and a date with the traffic court officer—is to employ radar detectors from the best radar detector brands.

Radar detectors are small portable devices that use radio transmitters to detect frequencies that are often associated with radar guns and alert the driver of the approximate location of the said speed gun.

On the right side of the law, speed gun utilizes radar technology to bounce off radio frequencies onto oncoming vehicles and approximate their current speed and location. These have been proven to be accurate and effective in catching drivers that are speeding along a stretch of highway or City Street.

Both speed guns and radar detectors have evolved over time but radar detector brands seem to be always abreast with the technology than law enforcement agencies, allowing chronic speed devils to remain uncaught. Even when police officers on the traffic beat are given LIDAR-based speed guns, radar detector brands seem to have found a way to protect their devices and detect these additional transmissions.

Filtering Radar detector brands

Modern technology is constantly evolving after every minute and every hour, and it is no surprise that there are a lot of radar detector brands competing in this niche market. But how do you know which radar detector brand is best?

Below are some features that are present in most radar detector brands but only a few models would have them in a single unit. These features should ideally be present in a radar detector model but do take note that some features would only be exclusive to a certain brand.

  • Double Antenna Design – experiments have shown that radar detectors that have two antennas are more effective as they can filter the frequencies better. However, front-facing double antennas are much better at this task than having one antenna upfront and a second one on the rear. Detecting radar coming from the back doesn't have much use since you've already passed it and most likely have avoided it.
  • Dual Signal Processing – this feature helps extend the range farther and the microchip compares the signals coming from a radar gun to those that often release the same frequencies but are not, in fact, radar guns. Examples of these include automated speed reminders and electronic billboards.
  • Stealth Technology – models with stealth technology would shut themselves off once they detect a radar gun within the general vicinity to avoid detection. This is nifty, and some models would have an auto-on capability for continuous detection once the danger has passed.
  • Shield Technology – compared to stealth, some radar detector brands would have the capability to make themselves virtually invisible to detection. Some areas do forbid radar detectors, and it is a definite advantage if the detectors can throw off transmissions that aim to unmask these devices.
  • OLED Display – these displays are much better than their LED cousins as they are more responsive. Additionally, the light that OLED emits does not have glare that can hurt the eyes of the driver, which can lead to an untoward accident.
  • Driving Modes – this is one of the newer features that detectors have begun to have. Driving modes allow the driver to select the sensitivity of the receivers. There are usually three modes: city, highway and auto; all three allow the detection system to calibrate with the built-in GPS and become more efficient in detecting false alerts.
  • Alarms and Notifications – you may have a radar detector that is very effective in getting you past speed guns, but their notification and sound alerts would alert authorities or at least some form of inconvenience with your passengers. A few radar detector brands have slowly migrated to a quieter notification system that lets you drive without being jolted by a sudden alarm from your device.
  • GPS Lock-on – built-in GPS systems calculate the general location of the vehicle and factor in their current speed at any time. Some models can even store the location of common false alerts and prevent the radar detection system from going off while near these areas.
  • Speed Gun and Red Light Mapping – a recent feature that is an offshoot of having GPS built-in with the radar detector. This allows the device to record where speed guns are often detected and warns the driver if they are approaching an area that would usually have a speed gun, even if there aren't any, which is a nice precaution. Some models can sync with the traffic light system, much like how TNVS companies do it and alert you if you are approaching a red light or an accident that is causing a slow-down in the traffic flow.

Benefits of Having a Radar Detector

Generally, having a radar detector is against the law in most locations as it does circumvent speeding laws and can help criminals get away with their illegal activity. However, it does have some benefits for ordinary, law-abiding citizens.

  • Avoid Tickets and Fines – detecting the presence of radar guns and making the vehicle invisible from detection lets one drive at the speed that they like while avoiding expensive fines and tickets that will go towards the permanent record of the driver.
  • Speed Control – OLED screens often would have the vehicles current speed displayed and it, of course, visually tells the drive that they need to slow down. Constant alarms and notifications would also tell the driver that the area they are in is a speed gun hotspot so driving at a slower pace should be observed.
  • Avoid Trial and Prison – owning and operating a radar detector is a violation of certain laws and if a driver is caught with one, they can be charged with a felony case that would often involve prison time and the revocation of their driving license.

The best radar detector brands would have models that would consistently have features like GPS lock-ons, speed gun mapping and silent notifications which give a huge advantage in terms of slowing down and going below the speed limit. Other features like dual antennas and dual processing systems are slowly becoming a norm, and they are effective when it comes to radar detection.

Nonetheless, exercise caution when operating a radar detector and choose one that would have both shield and stealth technology to avoid a felony charge.

How to Use a Radar Detector

How to Use a Radar Detector

If you like adventure and love to drive really fast, chances are you already know what a radar detector is. But if you don't know by any chance, the radar detector is a device that allows you to detect if your car or motorbike speed is monitored by police using a radar or laser gun while driving. This allows you to respond in time. But buying and owning a radar detector is not enough, you must also know how to use a radar detector properly.

Using radar detector can allow you to reduce car speed in time to avoid ticketing. This is a commonly used device by motorists who love to speed or race with others. The radar detector works by detecting various wavelength signals from the long distance that are used by speed detectors, mostly Doppler-based radar devices.

Enough with the basics; let's move on to the most important question—how to use a radar detector?

If you want to avoid a speeding ticket, you must have a radar detector. Most people buy it once they already got a ticket, but it is better to act proactively, right? However, a radar detector is not a simple device. You must have a clear idea how to use it before you run into trouble with the law enforcement once again.

How to Use a Radar Detector

First, you need to understand what it does. It is a device that only tells you about the signals it detects. It is you who need to translate the information and respond accordingly. Simply put, you also need to pay attention to what your radar detector is telling you.

Mounting a Radar Detector

What do you need to do after buying your first radar detector? You need to mount it in your vehicle, so where to mount it?

Even though radar detectors come with detailed manuals that also tells you where to mount the detector, the most common place most people use to mount the detector is at the center of the windshield.

That is the first mistake that car owners commonly do. The windshield is simply too high to detect laser guns used by police. While it can detect radar guns, it will fail to detect a laser gun. Police use laser guns to target the front license plate, which makes the laser rays too low for the radar detector.

Mounting radar detector in the middle of the windscreen is also bad for your view as it obstructs your vision. It also adds risk to your safety as you have to take eyes off the road to check it when it gets activated.

And above all, the chances are, if you left it in your car, you would not find it when you get back as it will be too exposed to thieves. Not only that, but police can also see that you are using a radar detector. Simply put, it is not a good idea to expose to the world that you are using a radar detector.

So what it the best practice? The best practice is to mount it low, use a Velcro to place it on the dash or use windshield mounting brackets to mount them low on the windshield. This will allow your detector to also pick laser guns along with radar guns.

Also, make sure that the radar detector is easily accessible from your driving seat. You must easily reach the mode and volume controls while driving, as stretching while driving can take your eyes off the road.

Understanding the Signals and Alerts

It is a useless device if you can't understand what it is telling you. To make it work best for you, you must have a clear understanding of signals, alerts, and correct modes.

Weak signal is often ignored by the drivers which is a common mistake and often result in a speeding ticket. Detectors alert by showing you signal strength and band, so what are these?

  • X band: This is the traditional and older radar band used by police in most of the US states. This is also one of the bands with the most number of false alerts, but nevertheless, you must respond properly when your radar detector detects this band.
  • K band: Almost one-third of the current radar guns used by the police use this band, so if your detector alerts you against this band, it is better to decrease your car speed.
  • Ka-band: If your radar detector shows this band, it is better to respond immediately as this is the most common band used in radar detectors by police.
  • Laser: Laser guns are becoming more and more common with police. Sometimes, your radar detector can misread reflection of bright sunlight as a laser, but false alerts are very rare.

Next, you need to look into the signal strength that is displayed in the form of a graph, or row of lights. The higher the graph or more the row of lights, the higher the signal strength, and closer the police detector is.

Next step is to understand modes because if you are not using the correct mode, you will be interrupted by false alerts.

If you are driving in a city, use the city mode. The city mode reduces the sensitivity of the detector as there are a lot of wavelengths and signals flowing around in a city. This will allow you to drive with a relaxed mind.

When you are driving outside the city, use Highway mode. By doing this, you can increase the sensitivity of radar detector to cover the longer range. This mode is also maximum performance mode.

In the modern radar detectors that come with a smart GPS feature, you can also have an auto mode, which switches between the highway mode and city mode based on your vehicle's GPS location.


We are sure you now have a clear idea on how to use a radar detector. By keeping these simple tips in mind, you can avoid police tickets easily using a radar detector. Indeed, it is a valuable device that can save you money, time, and a great deal of hassle, but still the best way to avoid the trouble is to drive safely and stay within the speed limit.

Radar Detector Basics: How Far Does a Radar Detector Work?

Radar Detector Basics

A radar detector can be an extremely useful tool for maintaining the speed limit while driving, but unless you know the radar detector basics, it is difficult to understand how a radar detector works.One of the prime questions that you need to understand before buying a radar detector that how far does a radar detector work.

How the radar detector works

Radar detector catches the signal of the speed radars use the traffic police so that they can control the speed limit of the cars running on the road as well as can find and fine the drivers disobeying the restriction on speed limit. On the other hand, sometimes a driver may overlook the speed limit because of ignorance or unawareness. In these situations, radar detector can help them to escape from traffic penalty in terms of fine and harassment of ticketing. However the efficiency of a radar detector depends on its range and some other features.

The range of radar detector

The range is the functionality limit of the detector. This denotes that signal range a detector can sense and read. Powerful radar detectors can detect the signal of police far before, actually before you can see the police car. Before you purchase a radar detector, you need to verify the range it offers. Radar detector models with 360-degree laser detection are accounted as more reliable, but these models are costlier than basic models. These detectors come with double sensors, out of which one covers the front and the second sensor covers the rear side of the vehicle you are driving.

Ability to reset in city mode/highway mode

The level of alertness about speed limit largely differs when you drive in city rather than your driving speed on highway. In fact you can drive with more speed and better level of relaxation in highway because highway speed limit is different and level of speed surveillance is  not that strut on highway. The radar detector can be set in either city mode or in highway according to your driving style and driving route.

Types of detectors

If your prime concern is “how far does a radar detector work”, you need to understand about different types of detectors, which offer different types of functionality.Commonly, three types of detectors are available in market. These are corded variety, cordless variety, and remote mount variety.

  • Corded models are installed on windshield and they are known for their most efficient detection range and capacity
  • Cordless variety can be mounted in the car as per your use. These portable options and does not require any special installation
  • Remote-mount detectors are everlastingly fixed to your vehicle, offering a tidy, uncluttered installation that's almost untraceable by thieves

Depending on your preference and driving habit you need to find the suitable detector for you so that you can enjoy optimum functionality.

Voice alert feature also works

This is one of the best improvisations that have been added in radar detectors to make them more functional for their user. With this feature on, the typical feature enabled radar detector conveys his signal detection message to the driver. As a result the drive can immediately check his/her car’s speed limit. There is no need to read the blue display on the detector’s screen. This advanced feature helps a driver to drive steadily while driving and it saves confusion and distraction while driving. The radar detection machines available with this feature will help you to drive in worry-free manner.

VG-2 and Spectre protection

VG-2 and Spectre protection are latest shielding a technology that allows drivers to be aware of the latest RDD technology where police uses radar detector detectors. This is a tricky situation and often keeps drivers at fix because they get caught for using the detector. Some of these gadgets use stealth protection feature that helps you to shut down the detectors immediately. Some expensive models provide invisible option. With this invisible feature, the radar detector works full-fledged without being invisible.

Instant-On Protection

It is a feature incorporated in almost all latest models of radar detectors but hardly has it given you complete freedom on speed management. If the speed measuring gun is aimed at you, it instantly reads the signal and will notify you. But this feature gets on when the detector gets the signal and mostly it gets too late to respond. Presently, a High K-band sensitivity feature is being used to offer the drivers instant on protection.

Radar with GPS

Latestdevelopment in GPS technology hasallowed radar detectors with better level of functionality than ever before. GPS works a global satellite network that initiate communicates with different devices to help in ground-based routing applications. GPS devices in cars cancorrespond with satellites while it is moving. These devices calculatelocation, speed, and direction down. GPS radar detectors can analyze where they are and how speedy they're going at any time by instantly communicating with the existing GPS network. This is a potential advantage over basic radar detectors because these devices can tell a driver when a radar is around you, but they cannotmeasure the speed off your vehicle actually.

Smartphone compatibility

Now some advanced radar detectors can work with smart phone compatibility. It is best done by apps, which are available both for androids and IOS devices.Detectors work in combination with your Smartphone, to provide you alerts provided by other app users for enforcement locations in your neighborhood. Some apps also allow drivers to emphasize enforcement areas they encounter, so that all users can be alert as well.

Some radar detectors work by transmitting alerts directly to the configured Smartphone via Bluetooth link, allowing the detectors to get the alerts on mobile screen in case these models are not built with display.

These are some of the ways a radar detector work. However, according to experts’ opinion, it is always wise to go for popular models only so that you can be sure about their productivity. Also it will solve your quandary about “how far does a radar detector work”.


What Does Ka Mean on a Radar Detector?

What Does Ka Mean on a Radar Detector

As radar technology keeps evolving, so do radar detectors. Keeping up with all those specifications on the package may truly test your patience. But there are some specifications that are more important than others, like the Ka band. So, what does Ka mean on a radar detector?

You need to know the answer to "What does Ka mean on a radar detector?" before you shop for a new radar. Equipped with the answer, you'll be able to find the best radar detector for your needs.

One of the devices police use to measure a vehicle's speed are police radar guns. Some of these use frequencies that fall within those of the Ka band.

To answer, "What does Ka mean on a radar detector?” we have to look at the different bands used by radar detectors first.

The Scientific Answer to "What does Ka mean on a radar detector?"

The Ka bandwidth (pronounced kay-ay) is a microwave band in the 26.5 to 40 gigahertz (GHz) range. It has wavelengths between slightly over one centimeter down to 7.5 millimeters. In addition to its use for vehicle speed detection, it's also used for satellite-based communication, as well as for cosmic microwave background experiments.

Police commonly use devices like the doppler radar or LIDAR to figure out the speed of a car. Radar detectors can detect signals across multiple wavelength bands.

What Does Ka Mean on a Radar Detector Compared to Other Bands?

The first band the police force used was the X band (10.500 - 10.550 GHz). During the 1970s and 1980s, it was cheaper to build police radar guns using this frequency than any other. Over time, K band (24.050 - 24.250 GHz) hardware became more affordable, and the police adopted it as well.

It wasn't until the 1990s though that police radar gun makers started using the Ka band hardware as well. Today, police forces across the US use radar guns that rely on all three bands.

This may seem a bit strange. Why don't they just use one single band for radar guns? Wouldn't that keep things easier?

What Advantages does Ka on a Radar Detector Bring?

As the frequency of the band for radar detection increases, the size of the hardware decreases. X band radar guns were big. They took up quite a bit of space and weren't the easiest to handle. K band guns were smaller, easier to take out and use. Ka band guns are the smallest to date.

Some of them don't even look like guns at all. Even better, they can be mounted in the police car, often in the light bars. This isn't only more convenient, but also safer for police officers.

But "older" laser frequencies have their advantages too. The usual X band radar gun has a beam width of around 65 degrees, compared to the 35 of the Ka band. In some cases, this can be useful, as the police officer can pick up the speed of the car even if he or she doesn't point the gun directly at it.

But not always. When two or more cars are driving side by side on a busy road, the greater width of the beam may pick up two or more vehicles. When this happens, the police officer may not know for sure which car was the fastest. Even if he or she saw which drove fastest, the gun may not provide enough evidence for a speeding ticket.

But if the police officer used a Ka band radar gun, the narrowed width of the bean would have allowed for finer targeting. Ka band hardware also comes with a better resolution across lanes, which further improves accuracy.

What Does Ka Mean on a Radar Detector for Police Departments?

For police departments, the Ka band also came with a major benefit. When it was first introduced, none of the radar detection systems cars could pick it up. That has changed now, with most of the devices on the market able to detect Ka band radar guns. Even entry-level devices without built-in GPS can now pick up the Ka band.

What Disadvantages Does Ka Mean on a Radar Detector Bring?

Ka band radar hardware is a newer technology, and so more expensive. That's the main reason why police departments across the country continue to use X band and K band radar gun detectors. Since most departments aim to have all their cars -- or as many of them as possible -- equipped with a radar detection system, it's easy to understand why older X and K band hardware is still in use.

What's more, this radar technology is still relevant and useful today, despite its larger size, greater detection width, and lower resolution. Many police officers are used to the old technology. Newer devices may require further usage training.

Another thing you should know about the Ka band is that it has a bigger susceptibility to rain fade and possibly other meteorological conditions. In other words, it doesn't do that well in cloudy weather conditions.

As you can see, the Ka band isn't without its limitations. Indeed, no radar gun is perfect. But police radar gun technology has advanced enough to make the detection of speeding drivers an easy job, at least most of the time.

The Conclusion to What Does Ka Mean on a Radar Detector?

When looking at the radar bands we've talked about so far, the K gun is the most widely used. The X band is still used in some parts of the country but is being slowly replaced. Ka radar gun technology is the fastest selling at the moment, and in a matter of years, it will probably supplant K band guns.

We hope we've answered, "What does Ka mean on a radar detector?". Not all the police radar guns in use rely on the Ka band, but enough of them do. So, make sure your detector supports it. Otherwise, that ticket they're keeping for you may finally be yours.

  • Instant-on ready
  • Anti-falsing circuitry
  • Efficient alert system
  • Audible options
  • Radar and laser protection
  • Speed monitoring capabilities
  • Clear and visible indicator signs


  • The stability clip can wear out


Each of these three products has a capable design that can identify relevant signals from large distances. The displays are also solid and provide similar features, more or less.

If you buy a radar detector, it should be a product capable of weeding the false signals out of the results with great efficiency. The Elenest system’s speed sensing auto mute function is capable of that to a degree, but not at the same level as the other two designs.

That is the main reason why the Elenest High Performance V15s Laser Detector doesn’t stack up against the two Cobras.

The competition had to be decided between the Cobra ESD7570 9-Band Performance Radar/Laser Detector and the Cobra Electronics RAD250 Rad 250. The winner is the Cobra ESD7570 9-Band detector, for the simple fact that it was able to match the efficiency and feature-rich design of the RAD250.

Both variants have the anti-falsing circuitry to reduce the number of false alarms. In addition to that, the ESD7570 has a number of other relevant features like the DIM button or easy operation controls, making it the winner of this radar detector comparison.

How to Conduct a Radar Detector Test

How to Conduct a Radar Detector Test

Before you set up your newly bought radar detector in your car and start driving around with it, you might want to conduct a small radar detector test. This way, you get to familiarize yourself with the device and try out all the features it provides. After all, the best way to get the most out of any piece of tech equipment is to first learn how to use it properly.

Why spend time reading dull instruction manuals when you can drive off with a few of your buddies and have a fun time performing a radar detector test?

In addition to getting to know the device, there are other benefits to conducting a radar detector test. If you still haven’t finalized your purchase, you can use this opportunity to compare a few models and decide which one’s the best. You also get to see how forests, curves, mountains, and different types of terrain affect the performance of your radar detector.

Finally, you’ll learn a lot about radar technology and begin to fully understand every bit of information the device sends your way.

You’ve probably watched a few videos and read some reviews before you went and bought a radar detector. People who created them have all conducted a radar detector test of their own and shared their findings so that others could benefit from them, too. You can give back to the community by sharing your test results with other folks who are interested in getting a radar detector.

Post a video to YouTube, publish a review on your blog, or find a dedicated message board and write there.

Most people use radar detectors to receive early warnings about speed monitoring devices ahead of them and have enough time to adjust their speed accordingly. With this in mind, we’ll explain how you can conduct a radar detector test that focuses on its ability to receive long range signals.

What You Need

To test the performance of your radar detector, you will create an obstacle course of sorts. This being a radar detector test, you’ll need to bring your detector. If you want to test multiple devices at once, bring them all along and try them out one at a time.

Don’t run two radar detectors simultaneously, as they will probably interfere with each other’s signals, and the results you get will be highly inaccurate.

To conduct the test, you’ll also need a radar gun. If you know someone who has one, ask them to lend it to you for a few hours or invite them to join you. Otherwise, you will have to get your own radar gun. There’s no need to spend a lot of money on it, as there are many inexpensive models available to buy from online retailers.

Because most of them are battery-powered, bring a USB cable or a standalone power supply to charge the gun in case the battery runs out.

For testing purposes, you’ll need at least two cars: one to serve as the radar and the other one equipped with a radar detector. If you’re going to be making a video, you’re going to need a camera. To ensure that the quality of the footage you capture is good, opt for a standalone model over the one on your phone. You will need your phone to measure the distance between the detector and the radar.

This can be done using the manufacturer’s official app; if there isn’t any, find a similar one in your app store.

Choosing the Location

The right choice of the location where you’ll conduct your radar detector test will ensure that the results you get are spot-on. For starters, keep in mind that different obstacles such as hills, curves, and trees will limit the detection range of your device. What’s more, the detector might not receive any signal at all in certain spots, so take that into account while writing down the results.

Make sure that the course you pick has a safe spot for you to park your radar gun-equipped car without it being in the way of other cars you’ll use for this test. To prevent the detector from sending you false alerts, choose a location that’s removed from heavy traffic, as well as other radar sources. For the results to be accurate, you will want to ensure that the weather is stable during the test.

Check the forecast ahead of your little adventure and avoid doing this in the rain, as it can limit the detector’s range.

Setting up the Equipment

Before you conduct the radar detector test, you need to prepare your equipment for the task. The radar gun should be pointed at the course so that it can detect all cars approaching it. You will also have to make sure that there’s nothing standing in front of it, as it will inevitably block the signal. Don’t move the radar gun or the antenna once you’ve set them up, as any change in their position will alter their ability to receive incoming signals.

The same thing applies to detectors: if you’re going to be conducting a radar detector test on several different models, they all need to be mounted in exactly the same spot on your windshield. You should clean your windshield of all items that could potentially interfere with the device’s signal. Finally, double-check the settings of the detector to make sure that each model you test has the exact same settings.

After you’ve finished setting up all the equipment properly, it’s go time!

You’re Ready to Go!

Turn the radar detector on and wait about a minute for all the features to load. Start driving from a point that’s as far removed from the radar gun as possible and note down all the results as they start coming in. Do at least two or three passes and compare the results you get each time. Whenever the detector sends you an alert, use the app to measure the distance between your car and the radar.

Learning new things can be very exciting, so don’t forget to enjoy this experience as much as you can. Also, remember that sharing is caring, so make the results of your radar detector test available to fellow enthusiasts.

Best Car Radar Detector

Best Car Radar Detector

More and more drivers today are relying on radar detectors to send them timely warnings about traffic monitoring devices along their route. These detectors are able to receive long range signals and alert drivers immediately, giving them more than enough time to adjust their speed and avoid getting a ticket.

There are many affordable consumer-friendly radar detectors out there, providing useful features drivers can benefit from greatly while on the road. It’s not enough for the detector to just be able to send alerts about radars and traffic cameras.

Recent models are equipped to detect more sophisticated monitoring devices like the red laser-based cameras used in some states. Some of them even have a built-in mechanism that recognizes false threats based on the signals received from a network of GPS satellites.

Syncing the device to your computer or your smartphone is easier than ever, too. Most manufacturers have released proprietary apps that allow you to plan your route in advance.

Users are also given access to framework and database updates; some of them are free, while some are only available to subscribers. In addition to this, some companies have crowd-sourced their data to provide real-time alerts based on the feedback submitted by their users.

With so many different models available right now, finding the best car radar detector can be difficult. To help you make an informed choice, we’ll take a closer look at three of the most popular models on the market.

Escort Max 360 Radar Detector

The Escort Max 360 Radar Detector utilizes two antennas – one in the front and another one in the back. This allows for 360-degree detection, which is something most other models on the market can’t compete with.

The main OLED display warns you about the monitoring devices ahead of you, while the four arrow-shaped LED lights on the side of the detector show you the direction from which the signal is coming. The device is GPS-ready and works on all four radar bands that are in use today.

You can choose between five different levels of filtering and select how much information you want the detector to show you. If you go for the Expert mode, you’ll receive warnings of up to four incoming threats at the same time.

In addition to the multicolor display, you can also opt to receive voice alerts. Free framework updates are available on Escort’s website, but you will have to subscribe in order to receive database updates.

You will also receive crowd-sourced real-time alerts once you connect the device to your phone. This is made possible thanks to the free EscortLive app.

When the two devices are synced, the app also shows real-time speed limit information as well as your driving speed at any given time.


  • Two antennas provide 360-degree detection
  • Directional LED lights on the side of the device show you where the radar is
  • Ability to see up to four alerts at the same time
  • Receives signals from GPS satellites to prevent false alerts
  • Fully customizable filtering
  • Multi-color OLED display for better overview and easier navigation
  • Real-time access to crowd-sourced alerts
  • The EscortLive app measures your current speed relative to the speed limit
  • Comes with a high-quality travel case


  • Considerably larger than other radar detectors
  • Not immune to the radar detector-detector (RDD) technology
  • Database updates available only to subscribers

Whistler Pro-78SE High-Performance Radar Detector

The Whistler Pro-78SE High-Performance Radar Detector is by far one of the most affordable models out there. This means that the manufacturers had to cut costs wherever they could.

For starters, the OLED display is the old dot-matrix OLED display which shows alerts in blue letters. On the bright side, you are given the option to adjust the brightness of the screen, as well as to turn on the voice alerts.

While it operates on all four radar bands, this detector isn’t GPS ready, which could potentially result in false alerts. To minimize their frequency, you can turn on the City mode.

The device will then filter out the signal interference caused by burglar alarms and automatic door openers. There’s no option to sync this detector to your phone, either. Instead of that, you get the INTELLICORD cable that allows you to remote control the main features of the device.


  • Compact-sized and easy to mount on your windshield
  • Works on all four radar bands
  • Three preset working modes including City mode and Highway mode
  • Customizable screen brightness
  • INTELLICORD cable allows remote control of the device


  • Not GPS-ready
  • High frequency of false threats
  • Detectable by RDD-based devices

Beltronics Pro 200 Radar/Laser Detector

The Beltronics Pro 200 Radar/Laser Detector is another model that doesn’t have built-in support for GPS signal. Luckily, false alerts are eliminated thanks to the use of traffic sensor rejection (TSR) technology.

This model is highly responsive: it takes only 500 milliseconds to warn you about a detected threat. It works on all four radar bands and has laser sensors for more accurate results.

The blue OLED display also shows a progress bar that goes up as you’re approaching the radar. You can maximize display visibility by adjusting the brightness to fit the lighting conditions.

Furthermore, if you find the voice alerts to be too loud, you can lower the volume instead of turning them off completely.


  • Fast response times
  • TSR technology utilized to eliminate false threats
  • Supports all four major radar bands
  • Built-in laser sensors for better results
  • Display brightness levels are fully customizable
  • Progress bar shows how strong the radar signal is
  • Voice alert volume control


  • Not GPS-ready
  • Isn’t immune to radar detector-detector devices
  • High rate of false alarms


All three radar detectors highlighted here have their fair share of qualities and shortcomings. Although they still remain very popular, which may have something to do with how affordable they are, the Whistler Pro-78SE and the Beltronics Pro 200 are largely outdated by today’s standards.

Still, they are excellent for beginners and those unwilling to invest in pricier models.

The Escort Max 360 offers several advanced features that the other two radar detectors simply cannot match. It provides real-time alerts for up to four radars at the same time and shows you the direction from which the signal is coming.

What’s more, the addition of the rear antenna results in an extremely wide detection range, making this the best car radar detector out there.

What is a Radar Detector?

What is a Radar Detector?

In today’s modern society the police force has several different options available to them when trying to catch people who are not following the law to an exact amount. The tool most widely used for this is the radar gun. The detector is used to catch drivers that are going over the posted speed limit on the road in which they are traveling.

The legality of this (or maybe the constitutionality of it) is a slippery topic, and it can certainly be called into question, but it does not change the fact that these devices are being used in mass numbers across the United States.

Whether it is a cop car sneakily parked behind large tree branches so he can catch unsuspecting drivers, speed cameras posted throughout our interstates, and even aircraft enforced speed limits. You can be sure that somebody out there is looking to catch drivers speeding to bolster their precincts bottom line.

But it’s not all bad for us as drivers; we do have a device that’s sole purpose is expressly meant to counter balance the over the top measures our police force uses to catch us speeding. This lovely device is called the “Radar Detector.”

Radar detectors have been in use since the 1970’s, and they do exactly what the name for them suggest they would do: detect radar guns. But to understand why they work, which ones work best, and how to utilize them to their fullest potential; you first need to know how these radar guns’ work.

Police Radar Guns

The radar guns used by the police are handheld Doppler radar units that measure the speed of objects that they are being pointed at (these can also be mounted on objects such as vehicles or poles on the side of the road).

They work by sending out a narrow radio transmission (for accuracy), and once that transfer hits its intended target, it sends back the transmission and utilizes the Doppler effect to determine what speed the vehicle is traveling at.

Due to the limitations that come with small radar units, the police force has strayed away from using radar guns and switched to the use of LIDAR guns, beginning in the early 2000’s. This is the reason you may have heard complaints from radar detector owners of not getting sufficient warning before having their speed detected.

Subsequently, the radar detector industry has been forced to come up with more innovative ways to be more efficient in this state of electronic warfare between our civilians and the government.

Counter measures

Out of necessity radar detector manufacturers have begun to develop more sophisticated devices to counter act the new technologies that are being introduced by the police force. For instance, they have implemented 360-degree measurements to be able to detect traps coming from all directions.

Recent technology has allowed today’s radar detectors to be able to operate without being detected by the police (this is an absolute must if you are in a state that deems radar detectors illegal). This technology is called VG-2 protection.

VG-2: How it Works and How it is Counteracted

VG-2 is the system that police use to determine who is utilizing radar detecting technology in their vehicles. It works by measuring the fluctuation in frequencies of radio waves to determine whether or not a radar detector is currently in use.

Often this technology is referred to as radar detector detectors (we will stick to calling it VG-2 for the sake of simplicity).

The way companies like Cobra and Escort utilize a technology that can determine when the VG-2 system is being used. When detecting police radar detector detectors, your radar detector will turn itself off (you should now be able to see why it's easier to use the term VG-2).

This is called stealth VG-2, and its purpose is to give you the warning and then shut down so that it cannot be registered as being in use.

There are also some units that provide “invisible detection” these are costlier than stealth protectors but they are shielded RDD (radar detector detectors), so they continue operating without the threat of being discovered, providing more consistent protection and giving you more confidence while driving.

Radars with GPS (Global Positioning System)

Today, many devices are beginning to come equipped with GPS. This is a powerful tool for helping the driver to avoid speeding tickets.

The GPS capability allows the unit to remember areas that you have been in the past where radar detection was being used, it can also alert you when you when the vehicles ahead of you have drastically reduced in speed (often indicating speed traps) so you can react accordingly.

Another great way GPS is utilized in these units is to send an audible warning when you are going much faster than the speed limit or the vehicles around you. This is perfect for drivers who don’t always recognize just how fast they are going (looking at you muscle car owners).

GPS also can adjust sensitivity relative to the speed you are traveling so that it won’t detect radars when it is unnecessary.

Smart Phone Capabilities

The newest addition to radar detectors is the ability to be paired with your smart phone. This is maybe the single best addition because it allows users to network with each other, giving real time updates of where there are speed traps.

Remember those days when we would communicate with other drivers by flashing our lights when there was an upcoming speed trap? It works just like that, except now you can alert more people.

Wrap – Up

Radar detectors have almost become a necessity for today’s driver. Speed traps are becoming increasingly more widespread, and with the advent of drones, the police force doesn’t even have to man these traps anymore.

It may seem to some that if you follow the laws, then you will be okay, but maybe that isn’t the right way to think of it. The more technology improves, the more the government uses it for the purpose of controlling the civilian population.

Radar detectors are one of the only ways we can take back some of our privacy. If the police want to catch us speeding, let’s make them work for it.
