  • 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.


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.  


  • 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.

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.
