Radar Detector Buying Guide

That is an easy answer if you find yourself always getting a speeding ticket or if you know that you have a lead foot. The benefits of a radar detector come from the preventative measures. We all speed. That is a fact of life. It is difficult to near impossible to know where on the highway patrol or local enforcement will be waiting to pick you off. You could be by yourself in plain view, or in a group of cars. There is no rhyme or reason.

Prevent the ticket before it happens with an instant warning. You can use a radar detector in your car or carry it with you in your work vehicle (check local laws for commercial vehicles). What would be worse than telling your boss you were late to a meeting because you got a speeding ticket?

Radar Detector Features

A radar detector isn’t very useful if it can’t pick up the right frequency, or the signal from a radar gun. When you install and operate the device it needs to work properly at the frequency selected. Most detectors have an auto-scan feature that picks up all supported bands used by law enforcement.

You should consider all the features below when purchasing a good radar detector:

Radar Band Coverage: Make sure your detector can pick up all three radar signal bands used by law enforcement: X, K, and Ka. You would rather have false positives and be able to slow down as a precaution, than to ignore the warning and get pulled over. Newer devices also have a new GPS feature that can show you an approximate location of the signal.

Radar Detector Range: Most radar detectors have a great range, and you’ll sometimes find yourself wondering for over a mile where the signal is coming from. Do keep in mind though, the layout of the land and environmental conditions can alter how your detector operates. A good radar detector will most likely have a setting you can choose for either city or highway driving.

Distinctive Sounds: Understanding the sounds and what is showing on the display screen is vital. Sounds can vary depending on the radar band, and if the signal you’re picking up is radar or laser. Make sure you know all the sounds so you know the difference between a detection or a false signal.

Informative Display Screen: The screen is usually simple, but helpful in many ways. It will display the type of band (X, K, and Ka), and even show the signal strength as you get closer or further away from the source. Depending on the model, other information can be displayed such as GPS, false signals, facing direction and much more.

Even if you buy the best radar detector in the world it goes without saying that if you can’t use it you will still get pulled over. So, it is vital that you get one that you can operate, while driving, at any time of day, and when you may be distracted by other things in the car.

By no means do we endorse speeding. If you’re one to naturally zip around the city or fly down the highway, we do recommend finding a solid radar detector considering the costly mistake of speeding tickets.
