As you can see, the most critical factor when choosing a radar detector is the type of safety alerts it provides. You need a detector that efficiently notices and alerts you about all signals, live police locations, and road hazards. Also, it’s crucial that the detector has different modes to choose from based on the road and situation

1. Cobra ESD 7570 – Best Overall


The Cobra ESD 7570 is probably the best budget option when looking for a quality radar detector. It’s effective and keeps drivers alert and safe. This Cobra detector features an ultraBright display, compact design, and digital signal strength meter.

Simply put, the Cobra 7570 provides the most effective way to get through urban areas that often have many types of radar and live police locations. This Cobra device is FCC compliant and one of the easiest ways to avoid speeding tickets and certain road hazards.

Many people said that the best place to use the detector was on a highway. It appears to pick up on many signals that aren’t significant even after it eliminates false alarms. To resolve this issue, you can turn the volume down, and turn off the XK bands. This will lower the possibility of picking up on unimportant signals around town.Pros

  • Small and doesn’t take up much space

For this reason, make sure tothoroughly learn what mode is the best for you and use the detector accordingly.

2. Whistler CR75 – Runner-up, Best Value


Whistler is one of the best brands when it comes to high-performance radar detectors. It features 360-degree coverage and protection. It’s especially effective thanks to its alert priority feature that eliminates any false alarms and prioritizes the most important signals detected. The Whistler CR75 easily detects and provides only relevant alerts on the X, K, KA, and laser signal.
The CR75 features protection blankets that detect all signals from the rear, sides, and front. Plus, it not only eliminates detection, but this radar detector-detector also features different modes to help you adjust to various situations. For example, its quiet mode, silent mode, and silence alerts are ideal for when you’re traveling at night and have people sleeping in your car.
Another impressive thing about the CR75 is the VG-2 detection and blinking LED light. These specifications and features eliminate threats, provide visual notifications and eliminate false-positive alerts. The device works as a digital compass, being one of the best pieces of electronics you can have in your car. Plus, the security factor is huge since detectors help you to drive more safely.

Some customers didn’t like its startup time. The device takes a minute or two to start up, which some people find to be way too long. However, this is a matter of preference and doesn’t affect the quality of its performance in general.Pros

The Cobra RAD 350 radar detector is one of the best devices with “instant on” protection. Its IVT (In-Vehicle-Technology) allows you to detect radar faster and avoid danger and speeding tickets. This technology also helps the radar reduce false alarms and false flags.
Its traffic flow monitoring device and vehicle collision systems make this technology even more important. Undoubtedly, it’s the right choice if you’re looking for the best detection speed and all-threats signals.The RAD 350 offers full protection from radar bands (X, K, Ka) as well as laser and VG-2 signals.
Not only does the radar detector have an ultra-bright display, it also features auto dimming. This, plus the quiet alerts feature are ideal for nighttime conditions. More so, the device is known for its digital strength meter and speeding alerts that are the two of its key factors.

Unfortunately, there’s a major problem with this device that some people didn’t like. Although the detector is ideal for nighttime, reviews say that its display doesn’t work as well in daylight. In case the sun is shining directly on the device, its icons appear as if they’re all lit up even if they aren’t. Unfortunately, there isn’t anything you can do to fix this since it’s the way the unit was built.Pros

  • Full protection
  • In vehicle technology
  • Speeding alert


  • Display doesn’t show well in the sun

If you can look past the user complaints, you’ll have yourself one of the best radar detectors on the market. It picks up on all the important signals, and it’s ideal for nighttime. Its technology makes it easy to use and detect all threats on the road.

However, when you compare this model to the Whistler Pro-78SE, we can see some clear differences. Some people like to compare them because of the Pro-78SE’s audio quality. Whistler made sure to make XTR-265 just as great for this reason.
One of the biggest differences between the two models is what they do to the life of your car battery. This model by Whistler is a much better car battery saver than almost all Whistler radar detectors thanks to its unique vehicle battery saver mode.

One thing that customers had to say about the Whistler XTR-265 is that it’s too quiet. It’s reported that the device isn’t loud enough, so you might miss out on some alerts if you’re maybe listening to music while driving.Pros

  • Car battery saver mode

  • 360-degree protection


  • Quiet

If you’re not a fan of listening to loud music while driving, this might be a good option for you. As a detector, it works effectivelyto discoverpotential dangers and police locations.

The detector gives you speed and red light camera notification reports on radar and laser brands, as well as all the traffic jams. Of course, its 360 degrees of protection help you to avoid accidents and other dangers on the road.

Many people say that the detector is set off by most of the signals it picks up on the road. Of course, this means there’s no chance that it will miss on a police locations or radar. However, it also means it might alert you whenever you pass automatic doors or different laser signals that aren’t relevant.Pros

  • Live traffic reports
  • Gives you directions
  • 360-degree protection


  • Generates many false alerts

This is an ideal choice for someone who lives in more rural areas or is often on road trips. If that’s you, you can be sure that it will alert you to any police locations.

Unfortunately, you won’t be able to listen to the radio while driving if you want to use the Cobra XRS 9370. Apparently, it produces a lot of static and weird noises that just make it impossible to listen to any music. Ideally, try and place the detector a bit further from the radio. That could help the situation just a tiny bit, if at all.Pros

  • VG-2 technology
  • Auto dimmer
  • Ideal for both day and nighttime


  • Can’t be placed near the car radio

Try and put the detector far away from your radio, or don’t turn the radio on at all. Without radio interference, you’ll have great protection from radar and other road hazards. This detector is packed with great features and it’s effective in helping you avoid speeding tickets and traffic jams.

8. Cobra XRS 9470 – Best Detection Range


Another great device is the Cobra XRS 9470 model which features extra defense and signal detection. It has 360 degrees of protection from front to rear of a vehicle and it’s able to detect signals from afar.

As is mostly the case with radar detectors, this device generates false alarms quite often. This happens most oftenin an urban area where you’re sure to get many notifications about signals that don’t matter. You can read the manual to see if there’s a way to stop it by changing some of the settings, or you can set it to highway mode at all times.Pros

  • City and highway modes
  • Alerts to road hazards
  • 360-degree protection


  • False alarms

There’s no question about its quality and effectiveness. This device will always alert you to relevant dangers but it will also alert you to things that aren’t as important. Surely, this can be annoying, but it’s not such a big of a price to pay to be safer on the road and avoid speeding tickets.
