Things to Consider Before Buying Radar Detectors

Things to Consider Before Buying Radar Detectors

These are the features that draw the line between good and great detectors. Remember that a lot of the detector’s likeability will depend on your personal preferences.

So prior to reading the find, try to find out exactly what you want from your detection gear.


One of the key aspects when it comes to purchasing a detector is the range. Models with poor range do not serve their purpose too well – what’s the use of detecting a police signal once they have spotted you already? This is why you should opt for models that have a good range.

However, only having front and rear detection fails to deliver great results, no matter how long the range is.

To detect signals from all sides and offer maximum protection, the detectors need to have ‘360-degree protection’.

If you purchase a 360-degree protection variant, you will be protected from the front, rear as well as sides.

Size and Mounting

Maximum detectors are designed to sit either on your dashboard with the help of a mounting kit or on your windshield using a suction cup.

All detectors may look the same at first, but the smallest differences in dimensions can be the reason your vision seems too hindered after installation.

Purchase the size and mounting system which coheres with the size of your car.

Laser Detection

Radar detectors are actually sufficient in detecting speed traps or police cars. So if that is your main purpose of purchasing a detector, you need not invest extra in models that are also equipped to detect laser.

However, if budget is not an issue and you would prefer maximum protection, some models offer both laser and radar detection, which would be worth looking into.

High K-Band Sensitivity

Many brands boast an ‘Instant-On’ feature, but what exactly is this? This feature means the detector has a high K-band sensitivity – which is the main band used by police forces to detect speeding.

The high sensitivity allows you to pick up signals from very far away and adjust your speed accordingly to avoid unnecessary hassle.

Furthermore, the Instant-On feature can also notify you when it detects a laser or radar pointer being used on a car immediate to you, so you are well prepared at all times.

FAQ’s of Radar Detectors

In case you are confused by all the models, features, pros, and cons, we’ve answered some of the most common questions you may have.

Are laser and radar detectors legal to use?

Radar detectors can be used legally and worry-free all across the USA except Washington D.C., Virginia, and all military bases.

Laser jammers, however, are illegal in several places, including Texas, Utah, Oklahoma, California, Illinois, Minnesota, etc.Are laser and radar detectors legal to use

What does the letter on my display mean?

The confusing letters or alphabets you see on your display are the different bands of radar used for surveillance and such.

Each band is used for a different type of purpose. It will prove greatly useful to familiarize yourself with all the bands and their uses prior to using a detector.

What are selectivity and sensitivity?

Selectivity and sensitivity are both very important features of a detector. Sensitivity determines how good the detector is at picking up a signal.

Whether it can pick up weak signals or not, while it is important for the detector to identify as many signals as possible, sometimes it can become a nuisance.

Automatic doors, garage doors, security systems, and several other everyday items also emit signals which can be detected by these machines.

However, how annoying would it be to be notified of a signal – only to find out the source is a shopping mall door?

This is where selectivity comes in to make sure you are notified of the relevant signals only.

Is a cordless detector a better option?

Generally, cordless models are more discreet and also leave your 12V port free for other uses, like charging your phone.

Because of such reasons, cordless models are becoming popular.

However, they do come with a heavier price tag, so it is all about what you think is more worth your money.

Help! Every detector I buy gives false alerts.

All detectors will, at some point, give out false alerts. This is almost unavoidable since so many technologies make use of radar and laser these days.

To avoid this problem, opt for models that have a good mix of sensitivity/selectivity and have different modes for the city and highway.

Final Words

As promised, our complete guide will guide you in your quest to find the high-quality radar detector under 150 dollars.

  1. Hardly do I do any type of long distance traveling without my great speeding
    detector somewhere inside of my own auto. I keep asking myself when actually did all of us become so terrified to cherish the legal
    rights we really used to take for granted? My genuine apology if I moved off topic for each time I read about radar detectors it
    makes me remember past ordeals before I invested in a very good one.
    I must confess this is a superb post and will be passing it on to my fan base on the usual social sites.
