Best Radar Detectors Under $150 - Buyer's Guide

Most people find it difficult to research the features they should consider while buying the best radar detectors under $150. Therefore we researched and compiled some features you should consider while buying a radar detector.

Display

First off, we have the display screen on the radar detector. Most radar detectors have an easy-to-read OLED display, while some have icon displays. The OLED display tells the driver about many things like band frequency and signal strength.

Moreover, the main difference is that an icon display might hit the light in your eyes which is not suitable for driving. While in an OLED display, the light coming from it can be either made bright or dull. So look for a radar detector with an OLED adjustable light display.

GPS

Now some radar detectors have built-in GPS while some don’t. Mostly cheaper radar detectors are excluded from it. Thus it’s your choice if you want a GPS in the radar detector or not. GPS is a must for a long-range radar detector.

False Alert Filtering

False Alert Filtering is something that avoids detections like from normal radar in shops or burglar alarms. Therefore if you move around the city most of the time, False Alert Filtering is a must. If a radar detector has an IVT filter, it means that it has the alert filtering featuring.

Band Frequency

There are 12 bands in total, including some of the best ones: K Band, KA band, and X Band. These bands are specific frequencies at which the police cars operate. The police use these frequencies to catch vehicles.

So if you are looking for the best radar detectors, choose one with the most band frequencies. Whenever one of the band frequencies is caught by the radar detector, it beeps.

Power

Most radar detectors work on 12V power. Some are wired with a power cord which is placed in the lighter plug. While some are wireless with batteries but the best one should have both in it. 12 Volts are significantly less for these powered detectors; they don’t even drain your car battery while they are on.

Alerts

There are two main types of alerts. One is the visual one which flashes when something is detected and shows the frequencies on the screen. And the second one is voice alerts.

So the voice alerts are considered better. You can adjust the volume of these voice alerts. However, not all the listed radar detectors have adjustable alerts; some are with fixed voice alerts.

Conclusion

Choosing the best radar detector under $150 won’t be a difficult task for you now. The radar detector will look good above the head unit. So get one and enjoy your ride and when you have bought it, do let me know your thought about it in the comments! Good Luck!
