Radar Detector Performance and Review Overview

What’s the point of having a radar detector if it’s not going to protect you when you need it most?

I rank my radar detectors differently than my competitors, who put together fancy graphs showing you how many miles away the detectors they promote were able to detect.

Why? Because most of them do their testing out in the middle of a flat desert, away from all the things that could interfere with the performance of the detector, thus giving potential customers an unrealistic view on how their detector should work.

My home and office is right next to the one of flattest stretches of highway in Arizona, the Carefree Highway, so it would be a lot easier for me to walk out my door and do a test just like my competitors do.

Radar Detector ReviewHowever let me ask you this:

When was the last time you drove on a highway like the one on the right, flat as far as the eye can see with little or no humidity, cars, trucks, buildings, hills or signs to reflect and block the signal?

I bet hardly ever.

Because of this, I do my testing differently, and measure my results by calculating the capture distance of a typical police K and Ka band radar gun.

Hi, I’m Radar Roy a retired police officer, certified traffic radar instructor and the founder of RadarBusters.

My 40+ years of experience has proven to me that the capture rate distance of a police radar gun is the most important factor that you should take into consideration when buying a radar detector.

Yes, it is a lot harder do the testing and reviews in this fashion. However, I believe it is worth the time and effort to give you the right information, so that you can choose the right detector for you.

Because I do my reviews in this fashion, I’m able to provide you a simpler way to choose the detector that is just right for you.

Cheap Radar Detector

For example, lets say you purchase one of the detectors that I rate as having a 1.5 capture rate of a police radar gun.

Well, by the time it takes your detector to properly interpret the police's radar gun's signal and react, you’re pretty much stomping on the brakes.

Now, on the flip side, by selecting one of the detectors I recommend with either 4 or 5 stars, you will have a higher likelihood of detecting instant on radar miles ahead, affording you plenty of time to slow down.

Also, these 4 and 5 star detectors typically provide adequate warnings if you frequently drive in areas with mountainous terrain.

Radar Roy's Radar Detector Star Rating Overview

There are only two radar detectors that I placed in 5 Star category: the Passport Max and the Passport Max 2.


Both of these detectors have superior range in comparison to any others on the market today, and they are also GPS enabled detectors, which puts both of them into a class by themselves.

Radar Detector RankingsNext, we have the 4 Star category, which contains any detector that uses Escort’s patent M3 dual antenna. This enables these detectors to have an extreme highway range and be stealth to all radar detector detectors. Thus, they are the perfect detector for the road warrior and/or professional driver.

Now, my 3-Star category of radar detectors are all based on Escort’s patent M4 antenna design, which provides you with ample range and performance for typical highway and city driving.

Then, in my 2-Star category, we have detectors that I estimate as having 3 times the capture rate of a police radar gun. This means that you have plenty of time to slow down in constant on-radar scenarios. However, you’re leaving yourself vulnerable by not being able to detect instant on radar miles ahead of you or in mountainous terrain.

Now, we have my 1-star category, these are typically the worst detectors, and, unlike my competitors who will sell you anything to make a buck, I refuse to sell them.

Frequently Asked Questions

What are the radar detector laws?

We have a guide for the radar detector laws in the US and Canada here. But for the most part Radar detectors are legal in all 50 states with the exception of the state of Virginia and the District of Columbia.

What is the Spectre Radar Detector Detector?

The Spectre is a device that police use to detect the presence of most radar detectors in vehicles. This device is used areas where radar detectors are illegal such as Virginia and the District of Columbia.

We have a video demonstrating how the Spectre IV radar detector detector works, along with a list of detectors that can defeat it.

Do you sell “invisible” radar detectors?

That depends on what you mean by invisible. These are the radar detectors that can defeat the Spectre.

These are the radar detectors that are designed to be concealed in your car.

Do you sell a radar detector detector jammer?

No we do not.

What does it mean to have a radar detector detector proof?

Some websites use this terminology to describe detectors that are stealth to the Spectre RDD.

Can the Valentine 1 defeat the Spectre radar detector detector?

No, it cannot
