Since the first radar gun and the first radar detector have been invented, an arms race of sorts has started. Wielders of the radar gun, members of the Police radar detecting info, attempt to catch drivers who drive over the speed limit. On the other part, the average Joe, owner of a radar detector, doesn’t wish to be caught speeding nor does he wish to be falsely blamed for speeding because of faulty gun.
This arms race causes manufacturers of radar guns to locate means of overcoming the capacity of radar detectors’ capability to detect them, and the other way around: manufacturers of radar detectors find ways of outsmarting radar guns – and also jamming their signal altogether.
Consequently, new models are occasionally released which are specifically aimed to handle the additional features of the ‘nemesis’ (for absence of a much better word). Just like an old radar gun is nearly certainly going to be useless against modern radar detectors, an old radar detector is definitely not effective against modern police guns.
The ‘arms race’ coming from a technical perspective – Radar detectors detect EM emissions from radar guns and trigger a security alarm for the driver that the radar detector can be used in the region. To be able to outsmart radar detectors, radar guns change frequencies to those that radar guns are insensitive to and thus, are effectively blind in their mind. However, once detector manufacturers figure this out, they enable their devices to become sensitive to these frequencies too.
Furthermore, some devices passively absorb the radar signal, and consequently, render the car invisible to the radar gun. Be aware that this could look suspicious to a police officer having a radar gun.
New radar guns use laser light (called LIDAR) as opposed to EM emissions. Older radar detectors would be completely ineffective against this type of radar gun. However, radar detector manufacturers have a way to circumvent that also.
Additionally, technology has been improving in other ways. By including GPS technology into radar detectors (as some model do, for instance, the Escort Passport 9500ci) radar detectors do not also have to detect the presence of radar guns – all they should do is connect with a database of people that have reported the actual existence of radar guns in certain locations, and wxzycl drive slowly during these regions. It becomes an impressive feat, though personally In my opinion the other side is already working on a means of circumventing that too – perhaps by creating numerous false alerts in order to make this database useless? We shall need to wait and discover.
From an academic perspective, it is really an interesting topic to follow along with. However, in reality, in order to use a radar detector, you must be certain it could cope with modern radar guns, otherwise, you might be setting yourself up for any very unpleasant surprise as you might discover youself to be overconfident because of your radar detector device.
To conclude: only by reading updated reviews of radar detectors you can be assured that you pick the right radar detector to suit your needs, which it will be good at nowadays. A final point: it is without saying that before purchasing a radar detector, you must make sure that using and possessing a radar detector is legal where you live and country.
