Best Radar Detector

Radar detectors have been available for approximately 40 years and during that time what made one-unit superior to the other has changed. In previous years, the most sensitive device that could alert you from the most significant distance was the most highly valued. However, recent improvements in technology have changed how consumers judge these devices.

What Is A Radar Detector?

A radar detector is a small electronic device that is used by drivers to detect whether or not their speed is being checked by law enforcement. These checks performed by law enforcement could be done from their own vehicles, through the use of radar guns or laser radar guns, or through the use of cameras.

Cameras are frequently employed to establish whether or not a motorist has stopped lawfully at a red traffic light, and modern radar detectors can detect these camera sensors and warn drivers. Radar detectors can detect a range of different bands and signals that use different wavelengths to communicate.

Most of the time, a radar detector is a tool to warn drivers so that they can slow down the speed they are driving and avoid getting a speeding ticket, but newer radar detectors have other capabilities beyond that and can even have custom settings.

Some radar detectors are sensitive enough to detect signals from everyday items such as automatic doors, and many are compatible with mobile devices and include GPS navigation capabilities.

Modern radar detectors can contain an impressive amount of computing power and can scan 360 degrees to find and alert drivers to threats. Some radar detectors scan in real time and share that information with other detectors as part of an online community database.

Buyer’s Guide


There is a lot to consider when purchasing a radar detector, but by considering what specifics are most important, you can vastly narrow down your options to one that suits you best.


All radar detectors will come with a user manual to help guide you through the initial set up and explain all of the features that may require customization. By working through the manual you’ll be in a better position to fully utilize the radar detectors’ features an implement them effectively in your vehicle as you commute.

User Experience

Many devices will connect to your mobile device via Bluetooth without much set up required. There are also a number of features that many radar detectors allow users to customize to their liking. How easy the customization is will vary from brand to brand, but many users find modern radar detectors to be very user-friendly.


Your budget for a radar detector will determine how many features and other capabilities that the device is capable of performing. There are a wide variety of devices available at different price points, and each one will have various features and accessories included.

Once you’ve established your budget for a radar detector, you’ll be able to narrow down your options and decide which features are most important. Pricier devices frequently have GPS features that update regularly and provide real-time data.

Even less expensive radar detectors can be very useful and accurate but will often come with fewer features and less complicated scanning capabilities. The displays will vary regardless of pricing, and other accessories fluctuate based on the brand of device.

Terms to Know

While shopping for the best radar detector for your needs, there may be some recurring terms that appear when the item's features are discussed. Here are the most commonly used ones that you'll want to know:

  • K-Band: This is a typical frequency used by radar guns which are handheld. Handheld radar guns typically operate in the range of 24.05 to 24.25GHz
  • Ka-Band: Law enforcement officers most commonly use this frequency which is in the range of 33.4 to 36.0GHz. Be advised that although this is the most frequently used range, officers have been known to use others as well.
  • X-Band: This band ranges from 10.5 to 10.55 and will catch all radar bands for things such as traffic sensors, law enforcement, automatic doors, and other sensors that are close enough.
  • DSP: Digital Signal Processing involves the use of a microchip that is designed to not only recognize different radar bands, but also prioritize them.
