About POP Radar

The POP™ mode isn’t error prone; it’s error riddled! The introduction of this new radar technology has left detector users vulnerable to unexpected ticketing. But what is the truth behind the claims made by local ticket writers? Let’s delve into the details of POP Radar and uncover the flaws that compromise its accuracy.
Unveiling the Flawed POP Mode
When operating in the POP mode, radars like the MPH Industries model BEE™ III produce erroneous speed readings. Even MPH Industries acknowledges this fault in the accompanying Operation and Service Manual, where it cautions against issuing citations based solely on information derived from the POP burst.
In our laboratory testing, we discovered why MPH Industries discreetly covers itself in fine print. The POP mode consists of a lightning-quick radar burst that lasts a mere 67 milliseconds, leaving radar detectors unable to detect the signal in time. Sadly, this burst exceeds the speed limit for the BEE™ III’s internal components, compromising its accuracy.
The Physics Behind the Inaccuracy
All traffic radar units rely on a stable reference frequency produced by a Gunn oscillator. This frequency must remain constant throughout the entire reading process. However, no Gunn oscillator tested has been able to turn on and off within 67 milliseconds while maintaining a consistent frequency. The start-up chirp that occurs during this short cold start phase when the temperature of the device is changing introduces frequency variations that affect accuracy.
Variables such as the distance to the target vehicle and its speed further contribute to potential errors. The further the distance and the slower the target speed, the greater the error. Additionally, the direction of the target’s movement adds or subtracts from the measured speed, compounding the inaccuracies.
The Moral Dilemma
By introducing the flawed POP mode, MPH Industries has ventured into questionable territory. In an attempt to outsmart detector users, they have created a radar unit that operates outside accepted engineering principles. To mitigate their technical recklessness, they’ve discreetly advised police operators not to use the BEE™ III’s key selling feature for its intended purpose.
Questioning the Future
- Question Number One: Will anyone actually read the warning, considering the widespread tendency to ignore manuals?
- Question Number Two: Even if read, will they heed the warning and refrain from relying on the flawed POP mode?
MPH Industries’ pursuit of corporate profits has led them to play an unconscionable game with law enforcement. Traffic radar units are primarily purchased as ticket machines, and by promising a feature while advising against its use, MPH Industries engages in deceptive practices. This not only creates a moral hazard but also threatens to corrupt enforcement.
It is imperative that MPH Industries takes responsibility and recalls all BEE™ IIIs promptly, disabling the fundamentally faulty POP mode.
Full-Time POP Radar Protection
While the flaws of the POP mode are evident, there are other radar detectors that offer full-time POP Radar Protection on two bands. These detectors prioritize accuracy and ensure that users are not vulnerable to misleading speed readings. Make an informed decision when choosing your radar detector, and opt for one that prioritizes your safety and peace of mind.
Remember, accuracy and reliability should never be compromised when it comes to ensuring road safety.
