FAQs and Buyers’ Guide

What Are Radar Detectors, Exactly?

The first thing you’ll want to know is: what exactly is a radar detector? Well: a radar detector is a device that is used to detect whether the speed of your vehicle is being monitored by law enforcement. Therefore, as you drive you’ll be kept much more alert as these handy devices act as a warning to let you know whether you need to decrease your speed while driving before running into any pesky police traps.

The range of best affordable radar detectors we’ve got for you (scroll up) all come with a range of features to provide you with key protection to a significant degree – the high performance of these products ensures that you can beat traffic, zoom down the city highway, and still not run into any trouble.

What Types of Radar Detectors Are There?

There are three main types of radar detector, and you’ll want to know the difference before you go searching on Amazon.

A corded radar detector tends to mount on your windshield via suction cups, and can look like a regular GPS from a distance.

A cordless radar detector is transported easily from vehicle to vehicle, and provides cleaner and more efficient installation due to its cordless technology.

A remote-mount radar detector is permanently mounted to your vehicle – providing a clean installation that’s frankly undetectable to car burglars – so these this type of detector presents a higher level of protection.

Depending on how you categorise, you may have also heard that there are two main types of radar detector – this will be referring to radar and laser. The former lets drivers know when a police officer is using a radar gun to catch speeding vehicles whereas laser detectors monitor both radar signals and newer laser signals that go undetected by radar detectors, which are more traditional and older.

Some laser detectors contain features such as red light camera notifiers – so these features are important to keep in mind.

Typical Costs of Radar Detectors

Before you search for the best radar detectors, you might also consider your budget and the price you’re after. There are an array of features that can affect the price of radar detectors, such as the availability of sensitivity and selectivity modes, commonly known as highway and city modes, and the level of long range distance afforded. Lots of radar detectors also come with a built-in GPS, which may up the price a little too.

Thankfully, as you’ll see above our list makes it incredibly easy for you to find the best affordable radar detector, as our selections range from $56 to $900. What a range!

Where is the Best Place to Buy Radar Detector Models?

The best cheap police radar detector is so easy to find, given the magic of today’s instant internet technology. Lots of reviewers and articles online will list their top picks, as we have here, and often the links to buy are included in the listing.

E-commerce affiliates such as Amazon are the greatest place to buy radar detectors, given that you can compare features and specs easily online amongst different models! Amazon also offers a brilliant warranty scheme so you can make any of your returns, all rights reserved, hassle-free.

Considerations Choosing a Budget Radar Detector

Before you have your pick of the best radar detectors, you’ll need to consider some handy tips we’ve compiled here for you to make sure you’re getting the right model for your needs, in order to help you avoid radar guns or red light cameras. You never know when you’re going to be caught out by law enforcement, so cheaping out on model may earn you an unwanted ticket. Here are our top 5 considerations for purchasing radar detectors.


The features offered by your model will be one of the most important things to watch out for before you get your shiny new purchase. For example, lots of detectors will have a speed camera notifier which alerts you where cameras are when you pull up to a red. In addition, speed trap detection can alert you when a speed trap is coming up. Some even offer in-app features using the iRadar app.

Corded versus Cordless

If you scroll to the buyers’ guide at the bottom, you’ll see we’ve outlined the different functions of corded or cordless detectors (which are pretty self-explanatory anyway). Cordless detectors offer more discreet installation, whereas the corded ones you can get are slightly more noticeable. So if you want to go under the radar, as it were, you’ll want a cordless model.

Range Capacity

You’ll want to pick a model from a reputable brand that offers a long range capacity which allows you to get lots of different frequencies and signals, such as K and KA band. These radar bands can be detected by the best radar devices in real time – so the better brand you go for, which doesn’t always mean the pricier band, the less chance of false alarms or false alerts you have – even from things like automatic door openers.

Display and Audio

These features are really important for when you’re driving at night, in darker circumstances. You’ll want a detector that has a good display that’s easy to read, preferable oLED display, as well as a good range of volume options. While the best radar detector will come complete with voice alerts and audible alerts, you’ll want one that features adjustable volume technology and even, ideally, comes with a mute option. This will give you protection for whatever situation you find yourself in.

Another part of display is considering whether your detector has app capabilities. Some detectors have an app you can use, such as an iRadar app, which increases convenience.

Highway and City Modes

The different areas you drive in will inevitably have different signal strength ranges. So, in order to avoid false alarms and false alerts, and have long range protection from law enforcement with real time signals – such as detecting the K Band or Ka Band signals of radar bands, you’ll want a high performance detector that has highway mode, and city mode. These accessories help to provide an advanced way of filtering out false alarms, to provide max efficiency at a cheap cost.

If you’re wondering how this technology actually works to provide you with max protection, highway mode will set your in-car detector to full sensitivity, providing much more opportunity for signal detection. This may increase the chance of false alerts. However, this is still comparatively a good filter to have because there’s a high chance that on the open road, these threats are real and not false alarms. City mode, in comparison, filters out false alerts by lowering the sensitivity.
