There are a lot of aspects to Consider of buying a radar detector.

• You Can’t Beat the feeling of relaxation that you won’t have to worry about a ticket or the inconvenience of getting pulled over when you’re just a little bit above a posted speed limit.

• Radar detectors are also very handy for those people that seem to not realize that they’re speeding at all. Long road trips can sometimes lead to complacency or a “rush to get there.” When this happens, drivers sometimes stop paying attention to their speed. These devices help keep drivers alert.

Important Features to Consider

First of all, It’s easy to get carried away and spend a bunch of money on a radar detector because of their benefits. Do you really want to pay a boatload of money, though, when you may not have to? There’s a lot to consider, and you need to decide just what kind of features you’re looking for:

• Radar Detector or Laser Radar Detector?
• GPS included?
• Does voice activate commands and usage?

Basic radar detectors can be very affordable, while one with all the “bells and whistles” will be more expensive. The good news is that there is a radar detector available for all budgets.

What Type of Detector?

Undetectable radar detectors:
The best types are undetectable radar detectors, but even within this category, there are a couple of considerations:

-Cordless Radar Detector:

You can enjoy plug n play it directly

-Digital radar detectors
are the small-ish piece of tech that drivers know when police and other speed checking methods authorities are using a radar gun to catch or trap speeding motorists. The basic models may be small and not have any additional features.
-Laser Radar Detectors:
A combination detector of radar and laser will scan for both types of speed monitoring devices: radar guns and laser guns. This makes it easy to keep up with (and beat!) the latest technology.

Which Brand is Best?

We wouldn’t recommend anything but the most reliable, well-built radar detectors. We stand with our recommendations on this page!


Cobra is far and away from the most well-known and popular brand of speed detection systems amongst private consumers. They have been in business a long time and have built some of the best radar detectors in the industry. They have models that work with iPhones. The same models will work with Bluetooth on the Android platform to alert of more than just speed traps but also safety hazards such as road construction, red-light cameras, etc.


Did you ever think to yourself: I wish I had a device that told me if there were speed traps and police up ahead that also had a GPS on it? If you did, you were probably thinking of a radar detector made by Escort. They offer a wide range of radar detectors, so if you’re looking for something a little higher or lower end, then Escort has the product you’re looking for.


How good are Whistler radar detectors? Check this out: A certain Whistler radar/laser detectors come with a cloaking device to help read any type of laser gun, even ones that are set in what in the industry is known as “stalker” mode. This would be in the best interest of the fastest drivers, the ones with a “lead foot.” If you drive a fast car and often put that power and speed to use, then Whistler will have the radar detector for you.

Top 3 Frequently Asked Questions about Radar Detectors

• Why does my radar detector keep going off with no police around?

There are many items, other than police radar guns, that will cause the radar detector to go off. Some of these include garage door openers (even automatic doors in grocery stores and drug stores). Also, if you’ve ever been driving down a street and see one of those warning boxes that tell you “Your Speed is…” and then start to madly blink when you surpass the speed limit…yeah, they can set off a radar detector, too.

• I just passed a cop! Why didn’t my radar detector go off?

This is a fun question that we love to be asked because it’s fun to answer! A radar detector, whether undetectable or not, is not a “police detector.” LOL. If the authorities don’t have an active radar gun or are running some sort of radar-based speed monitoring tech, then there is nothing to detect, and your radar detector won’t go off.

• Are Radar Detectors Illegal?

In most of the country, yes-radar detectors ARE legal. However, in Washington D.C. and Virginia, they are not permitted. Also, on all military installations, radar detectors are not allowed, and you will be stopped at entry gates for having one visible. (That’s why it’s best to get one of our recommended “undetectable radar detectors.”

Note: Don’t get radar “detectors confused with radar “jammers.” Radar jammers are illegal in 40 out of 50 states.

3 Important Facts to Remember About Radar Detectors

Fact 1

Some windshields will reduce the radar detection range by up to 95%! Most windshields are okay. Factor installed, and those in cars that are bought off the lot usually won’t deter the range of your radar detection unit by enough to worry about. However, there are some types of laminations and “tints’ horribly affect radar detection effectiveness.

Lamination on a windshield with metallic film (the silver-based film is the worst!) is used to reflect infrared radiation from the sun and, thus, deflects the radar detection. It’s best to know what kind of lamination or tint film you have before using a detector.

Fact 2

Is it possible for Police Radar Speed Tech to Be Faulty? You betcha’.There are often anomalies or “errors” associated with detecting speed with radar. It is less common to see an error with a stationary radar gun that police use.

Detecting moving speed from another moving object is must more difficult, though. “Shadowing” and “splitting speeds.” Shadowing and splitting speeds happen when the moving radar locks onto a different moving object that is in front of a car, like another car, and then adds both speeds together. Although this is happening less and less, it still does occur.

Fact 3

Are radar detection companies’ claims of accuracy honest? For the most part, “yes.” Many of these companies are trusted not only by private consumers but by municipalities and private security firms. They are bound to accuracy in order to stay trustworthy. Buying one of the undetectable radar detectors that we recommend on this page will help to ensure that you’re getting a quality piece of tech that is made by a trustworthy manufacturer.

Final Analysis:

Buying a radar detector isn’t as simple as it sounds, and there is a lot to consider for getting an accurate radar detector. Here on our site, you can find some helpful info about the best undetectable radar detectors that are within your budget.
