  • No more speeding tickets
  • You know when to slow down and when to speed up
  • Your attention is not divided between the road and your speedometer
  • 360-degree protection
  • No need to rubberneck to pinpoint approaching surveillance spots

Choosing A High-Quality Cordless Radar Detector

Mounting Style/Location

Even if you buy the best cordless radar detector or something standard for safekeeping and accurate results — you need to mount it in the right place. Car owners can mount their cordless radar detectors on the dashboard or put it on the inside of the windscreen. The chosen device may have suction cups or a mounting harness. If there is no harness, do not worry, there are a lot of options available in the aftermarket.

If you need a cordless radar detector for a motorcycle, you need to remember that there is no covering, unlike a car, so your detector has to be a snug fit. Depending on your chosen device, you can install it to the handlebar, brake or clutch area, fork tube, side mirrors, or the fairing area.

Speed Receptiveness

The higher the sensitivity of the radar, the safer you will be. So the best cordless radar detector on the market will allow you to adjust the sensitivity as per your discretion. For open highways, it is best to operate on high sensitivity and detect all upcoming signals. But when driving on a busy city street, the sensitivity should be set low, as your device will pick up on all unnecessary signals, i.e., automatic doors, car alarms, and other radar detectors.

Detection Range

A good cordless radar detector should be able to detect all signals that come forth from police radar guns and other surveillance equipment from a distance. You should have ample time to reduce your speed. Learn more about the different signal bands further on in this article.

Display

One common feature among the best cordless radar detector units is their good display — everything is crystal clear at a glance. A driver needs to pay attention to the road and not the screen, which is why it is best to choose a cordless radar detector with a decent-sized display.

Updated Database

Choose a radar detector that comes with a considerable arsenal of pre-loaded maps that pinpoint the exact location of fixed and mobile surveillance spots. You should have the option to record if you come across a surveillance point that was not detected by the radar.

Your device should allow you to upload new maps and surveillance points seamlessly — should you decide to move elsewhere.  

Features

  • Voice Alerts (Safety Feature)
    Whether you drive at high speeds or stay within the speed limit, you need to keep your eyes on the road at all times.This is why the best cordless radar detector should have voice alerts — every time there is a threat ahead, the device will let you know.
  • Indicators (Light or Sound/Volume Button) 
    Having a volume button on your cordless radar detector is an added plus — turn it up on noisy streets and bring it down when you want to drive in peace.
  • City/Highway Mode
    Having the ability to shift between city and highway mode is needed for accurate findings. When using the highway mode, the sensitivity is cranked, and all sorts of signals are picked up by the device. When on the city mode, though, the device has low sensitivity.
  • VG-2 Alert & VG-2 Non Detection
    You wouldn’t want law enforcement agencies to know that you have a cordless radar detector, even if it is legal in your state to own one.The best cordless radar detector on the market will have VG-2 non-detection, which limits law enforcement officers from detecting your device.VG-2 is an RDD technology that detects changes in frequencies from a particular band. You can go for a detector that features a stealth mode – which recognizes a frequency change and turns off – or a sensor that has invisibility protection or VG-2 non-detection.
  • Laser Detection
    It would be good to choose a detector that also picks up on police laser radar guns. Many of the top models have the laser-detection option.
  • False Alerts Filtering 
    Imagine continually getting false alerts — not only is it annoying, but it can be dangerous too.The problem is that your device detects a variety of signals, many of which aren’t important such as signals from automatic doors, car alarms, and other radar detectors.The best cordless radar detector devices allow you to shift between modes and sensitivities. The display also shows the band of the received signal, which helps you deduce if you should be concerned.If the chosen cordless radar detector has a built-in GPS, deciding between real and false alerts becomes easy.

Price & Warranty

Everyone wants something that performs well while making sure that it doesn’t burn a hole in your pocket. The price of cordless radar detector units varies significantly, ranging from $100 to over $1500. When opting for a cheap cordless radar detector, make sure that you receive good value for money.

You do not want to end up with a device that has a lousy battery or gives out false alarms. Warranties vary from manufacturer to manufacturer. Ideally, you should receive coverage for a year. But the longer the warranty period, the better!

Bands Used By Cordless Radar Detectors

When in the market to buy a cordless radar detector, you need to choose a system that can operate on low as well as high sensitivity. It should alert you of all threats in advance.

The capabilities depend on the frequency and band your device can detect, and a cordless radar detector should be able to pick up three common frequencies — X-band, K-band, and the Ka-band.

  • X-Band
    This is the most widely used band and operates at the lowest rate. Its radar waves fall between 10.5 to 10.55 Gigahertz.It can be detected from a distance of 2 to 4 miles and is the oldest type of signal emitted by police radar guns. However, many police radar guns do not use X-Band anymore due to unnecessary false alerts.
  • K-Band
    Law enforcement agencies started using radar guns that relied on the K-Band frequencies a decade or so ago. The frequency can be picked up from quarter to two miles away and functions at a wavelength of 24.05 to 24.25 Gigahertz — it falls under the microwave range of frequencies.
  • Ka-Band
    The latest and most advanced of the three is the Ka-Band. It operates at a frequency between 26.5 to 40 Gigahertz, which equals wavelengths of one centimeter to 7.5 mm. The best part is that as opposed to its predecessors that operate on a single frequency or two, the Ka-band supports up to five frequencies. This is the most familiar and reliable band, which is why law enforcement officials rely on radar guns that feature the Ka-Band. There are two sub-variants of the Ka-band — the Ka Wide-Band and the Ka Super Wide-Band. So when picking out the best cordless radar detector, you should pick a unit that supports these frequencies as well as laser detection to make the right move every time!
  • Ku-Band 
    Though the band is not commonly used in the US, it is widely used in European countries and operates on a wavelength of 12 to 18 Gigahertz.

Setting Up & Using A Cordless Radar Detector

Setting Up A Cordless Radar Detector

Hopefully, after thorough research and going through our guide, you have gotten your hands on one of the best rated cordless radar detectors.

Now is the time to mount it to your car, the good news is that you do not require an expert to do so — installing a cordless radar detector is a seamless process since there are no annoying wires. Your device either mounts with the provided mounting gear or by using suction cups on the base.

  • Mount To The Windshield 
    With a cordless radar detector mounted high on your windshield, the results are excellent, especially when you drive on inclined roads.If your windshield has a metallic tint, the results can often be not accurate. But if you have a ceramic tint, the performance of the radar won’t be affected. Many US states have laws in place that do not allow for cordless radar detectors to be mounted on windshields.
  • Mounting It On The Dashboard
    The second option is to place your detector on the dash, which is a very convenient place for installing portable cordless radar detectors. Here is a video to help you with where to install your radar detector.
Using A Radar Detector

Once mounted, switch on your device and start driving around. Initially, you will come across many false alarms due to signals emitted by automatic doors, ambulances, and other radar detectors. You have the option to adjust the frequency manually or choose between the Highway or the City mode for better readings.

The good news is that many of the best cordless radar detector units are scalable, they learn with time. The device will self-tag false alerts and ignore them the next time. They will also mark fixed speed cameras and red lights on your routes; so you can adjust your speed accordingly.

Understand Alerts

With time you will understand how your device operates, and you will be able to distinguish between real and false alerts. For instance, if the device encounters a Ka-band signal between 26.5 to 40 Gigahertz, it is probably coming from a radar gun. Similarly, if the device shows a V/L sign, there is a LIDAR gun at a close distance.

Choosing The Right Display Mode

For easy readability, many cordless radar detector units allow you to choose between different display modes. The best cordless radar detector will allow you to choose between — bright, dim, and a dark mode.
