Since the very first radar gun and the very first radar detector have been invented, an arms race of sorts has started. Wielders of the radar gun, members of the sites.google.com/view/rated-radar-detector, try to catch drivers who drive over the speed limit. On the opposite side, the average Joe, owner of the 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 discover way of overcoming the capacity of radar detectors’ capability to detect them, and the other way round: manufacturers of radar detectors find ways of outsmarting radar guns – and also jamming their signal altogether.
Consequently, new models are occasionally released that are specifically aimed to handle the extra features from the ‘nemesis’ (for absence of a better word). The same as a classic radar gun is practically certainly going 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 a burglar alarm for the driver that a radar detector is utilized in the area. So that you can outsmart radar detectors, radar guns change frequencies to those that radar guns are insensitive to therefore, are effectively blind for them. However, once detector manufacturers figure this out, they enable their devices to be responsive to these frequencies also.
Furthermore, some devices passively absorb the radar signal, and consequently, render the vehicle invisible towards the radar gun. Remember that this can look suspicious to some police officer with a radar gun.
New radar guns use laser light (called LIDAR) rather than EM emissions. Older radar detectors would be completely ineffective against this type of radar gun. However, radar detector manufacturers have a means to circumvent that also.
In addition, technologies have been improving in alternative methods. By incorporating 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 presence of radar guns – all they have to do is connect to a database of individuals who have reported the actual existence of radar guns in certain locations, and wxzycl drive slowly in these regions. This is an impressive feat, though personally I believe one other side is already focusing on an easy method of circumventing that too – perhaps by creating numerous false alerts in order to make this database useless? We shall have to wait and find out.
From an academic perspective, it is really an interesting topic to adhere to. However, in reality, if you wish to utilize a radar detector, you have to be certain it could cope with modern radar guns, otherwise, you may be setting yourself up for a very unpleasant surprise as you may discover youself to be overconfident due to your radar detector device.
In summary: only by reading up-to-date reviews of radar detectors you can be assured that you select the best radar detector for your needs, which it will be effective in this day and age. One last point: it is going without saying that prior to buying a radar detector, you must make sure that using and having a radar detector is legal in your state and country.
