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 read more, make an effort to catch drivers who drive over the speed limit. On the other side, the normal Joe, owner of a radar detector, doesn’t want 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 find way of overcoming the ability of radar detectors’ capability to detect them, and the other way around: manufacturers of radar detectors find methods for outsmarting radar guns – and even jamming their signal altogether.
Consequently, new models are occasionally released that are specifically aimed to handle the extra features in the ‘nemesis’ (for insufficient a better word). Much like an old radar gun is nearly certainly likely to be useless against modern radar detectors, a classic radar detector will never be effective against modern police guns.
The ‘arms race’ from a technical perspective – Radar detectors detect EM emissions from radar guns and trigger an alarm towards the driver that a radar detector can be used in the region. So that you can outsmart radar detectors, radar guns change frequencies to those that radar guns are insensitive to and so, are effectively blind to them. However, once detector manufacturers figure this out, they enable their devices to get understanding of these frequencies too.
Furthermore, some devices passively absorb the radar signal, and consequently, render the automobile invisible for 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) as opposed to EM emissions. Older radar detectors would be completely ineffective against this type of radar gun. However, radar detector manufacturers have a method to circumvent that also.
Additionally, technology has been improving in alternative methods. By including GPS technology into radar detectors (as some model do, as an example, the Escort Passport 9500ci) radar detectors usually do not also have to detect the actual existence of radar guns – all they have to do is get connected to a database of people that have reported the existence of radar guns in certain locations, and wxzycl drive slowly within these regions. It is really an impressive feat, though personally I think the other side is already focusing on a means of circumventing that as well – perhaps by creating numerous false alerts 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 practice, in order to use a radar detector, you must be certain it may deal with modern radar guns, otherwise, you might be setting yourself up for a very unpleasant surprise as you may find yourself overconfident from your radar detector device.
In summary: only by reading updated reviews of radar detectors you can be certain which you pick the best radar detector to suit your needs, and that it will likely be effective in this day and age. One final point: it is without proclaiming that before buying a radar detector, you must make sure that using and having a radar detector is legal where you live and country.
