"Plenty of anti-radar in the car, and now I'm not afraid of the fines!" many motorists say. However, they confuse the concepts of "radar" and "radar detector", as well as overestimate the possibilities of this instrument. So, what's the radar and the radar detector and what's different?
The radar is a serious device that detects a radar signal and sends a more powerful signal to its response that is "jammering" and causing it to show incorrect information. Anti-radars in Russia are legally prohibited, so it will not be able to buy and put it legally. The use of the radar is a major fine and the confiscation of the device.
And the fact that most motorists call "radar" are actually a radar detector. This device is just picking up signals from radars and signals them. Radar-detectors are sold in Russia legally, so one can buy such a device.
However, usually when a driver's radar detector is chosen, the driver has a lot of questions: " Which detector is better to buy? What are the parameters to pay attention to? Is it possible to save and take the cheapest? "
The lower the radar detector, the more signals it will take. But do not think that it is his dignity: in addition to the signals from the HYDRA radar or the complexes, such an instrument will "catch" signals of transmission lines, automatic doors and other extraneous sources. As a result, it will be practically continuous, and it will be virtually impossible to distinguish the warning about the radar from a "false call".
The police radars and the video fixation complexes have different ranges of work. Consequently, the radar detectors are designed to operate in different ranges. The main range used in Russia is K. Until 2012, the range X was also used, but then it was prohibited by law. Therefore, if the radar detector you have chosen does not support the "American" Ka or Ku ranges, it is not worth to worry-there are no radars on our roads.
One of the main characteristics of the radar detector is the sensitivity. It is up to her how far the device "sees" the radar and will be able to report it to the driver.
Another important metric is the reception radius. It's best if the radar detector works 360 degrees, so that no radar can go undetected.
Radar-detectors with built-in GPS modules have been gaining popularity recently: they not only record the radars of their emitted signals, but also check with the available memory card, which is the location of the video complexes. In addition, thanks to the GPS module, the radar detector monitors the speed of the vehicle and only gives the signal if the driver exceeds the maximum permissible speed.
Note that it is far from not in all countries that radar detectors are allowed to use as in Russia. If you're going to be in a car abroad, it's better to know in advance how the local police will treat this device. In most European countries, the import and use of radar detectors are prohibited and punishable by a fine.
