Which Whistler radar detector is best?

You should never drive recklessly or purposefully exceed the posted speed limit, but you also don’t want to get caught unintentionally speeding either. The purchase of a quality radar detector can offset the cost of just one speeding ticket. If you happen to have a heavy foot on the gas pedal, a Whistler radar detector is well-worth the investment. 

You have many choices when it comes to purchasing radar detectors, and different brands offer different features. Whistler is one of the most well-known and respected brands in the industry. It has a variety of products to fit just about any budget. For top-of-the-line protection, our top pick is the Whistler CR93 Laser/Radar Detector

What to know before you buy a Whistler radar detector

How radar detectors work

When working properly, radar detectors identify radar signals utilizing radio waves, acting as a radar receiver of those frequencies. For police, those frequencies are primarily K-band, Ka-band and X-band.

Radar detectors alert you to the presence of radio waves used by police radar devices. They don’t jam the signal or prevent police from detecting your true speed. 


One good thing about all Whistler radar detectors is that they offer 360-degree protection, which means that they can detect signals from all angles—something not every brand can guarantee. 

False Alerts 

A radar detector is only useful if it is accurate, and it doesn’t do you any good if you’re constantly receiving false alerts. There are a number of radio waves around us stemming from different devices which can accidentally set off a lower-quality radar detector. Higher-end Whistler models have built-in filters to weed out those other frequencies, preventing false alarms.

What to look for in a Whistler radar detector 


Whistler radar detectors have a suction cup that allows you to attach them to your front windshield. Ideally, the radar detector should be in the center and pointed down. Whistler radar detector batteries can be charged with an included cable that plugs into the car’s lighter or 12-volt DC socket. 


Depending on the model, the radar alerts you receive may be audible and occur in a series of beeps. Some models also offer Real-Voice alerts. Higher-end models may offer a visual-alert option that appears on an LED display screen. These models often provide additional useful information like the strength of the signal. 

Safety features

Whistler radar detectors do more than simply alert you about police radar. Some have alert functions that can help keep you awake if you fear you might nod off while driving. Some models also have alerts that can notify you of issues such as traffic accidents and railroad crossings.  

How much you can expect to spend on a Whistler radar detector 

The least expensive Whistler models are usually $55-$100. Reliable, midgrade models can be found for $100-$150. The highest-quality models with top-of-the-line features and the most reliable detection can cost over $250. 

Whistler radar detector FAQ

Is it legal to use a radar detector?

A. Before purchasing any radar detector, it’s important to check the laws for any state you plan on driving through. Laws vary from state to state, and radar detectors are completely illegal in Virginia and Washington D.C. 

Should you hide your radar detector from the police if pulled over?

A. If it’s legal in your state, there is no penalty from having a radar detector in your car, but it may or may not influence an officer’s decision to write you a ticket.
