Since the first radar gun and the very first radar detector have been devised, an arms race of sorts has started. Wielders of the radar gun, members of the sites.google.com/view/rated-radar-detector, make an effort to catch drivers who drive over the speed limit. On the opposite side, the normal Joe, owner of the radar detector, doesn’t wish to be caught speeding nor does he want to be falsely blamed for speeding because of faulty gun.
This arms race causes manufacturers of radar guns to locate method of overcoming the capability of radar detectors’ capability to detect them, and vice versa: manufacturers of radar detectors find methods for outsmarting radar guns – and also jamming their signal altogether.
Consequently, new models are occasionally released which can be specifically aimed to handle the additional features from the ‘nemesis’ (for insufficient a much better word). Much like a classic radar gun is nearly certainly likely to be useless against modern radar detectors, an older radar detector will not be effective against modern police guns.
The ‘arms race’ coming from a technical perspective – Radar detectors detect EM emissions from radar guns and trigger a burglar alarm to the driver that the radar detector is utilized in the community. In order to outsmart radar detectors, radar guns change frequencies to those that radar guns are insensitive to and thus, are effectively blind to them. However, once detector manufacturers figure this out, they enable their devices to get responsive to these frequencies also.
Furthermore, some devices passively absorb the radar signal, and consequently, render the car invisible to the radar gun. Note that this could look suspicious to some police officer with a radar gun.
New radar guns use laser light (called LIDAR) instead of EM emissions. Older radar detectors will be completely ineffective against this sort of radar gun. However, radar detector manufacturers have a means to circumvent that also.
In addition, technology has been improving in different ways. By including GPS technology into radar detectors (as some model do, as an example, the Escort Passport 9500ci) radar detectors do not always have to detect the actual existence of radar guns – all they need to do is connect to a database of people who have reported the existence of radar guns in certain locations, and wxzycl drive slowly in these regions. It becomes an impressive feat, though personally I think another side has already been working on a way of circumventing that also – perhaps by creating numerous false alerts in order to make this database useless? We shall need to wait and see.
From an academic perspective, it is really an interesting topic to follow along with. However, in reality, in order to utilize a radar detector, you must make sure it could handle modern radar guns, otherwise, you may be setting yourself up to get a very unpleasant surprise as you may end up overconfident from your radar detector device.
To conclude: only by reading updated reviews of radar detectors you can be certain which you pick the best radar detector for your needs, and this it will be great at this day and age. One final point: it is going without proclaiming that prior to buying a radar detector, you need to make sure that using and owning a radar detector is legal where you live and country.
