8.5 Mobile Laser
Laser guns fire quick pulses of light in a straight line which bounce off
your car and return to the gun. The beam of light is very narrow and will
spread slightly over a longer distance. The laser gun measures how long
it takes for the return beams to arrive back at the gun and because the
whole process works at the speed of light, the laser gun can calculate a
vehicle’s speed in less than one third of a second.
GPS systems can provide reminders when you are approaching an area
where a laser gun might have been used in the past, but they do not tell
you if laser is actually being used there now. GPS systems do not “detect”
anything - they simply provide a safety alert to remind you that you are
approaching a map location.
Most radar detectors on the market also contain a laser detector, however
please be aware that “detecting” a laser hit often only means that your
speed has already been recorded.
The GPS Mirror can integrate with a range of laser jammers from the
leading brand manufacturers, but please note that the legality of laser
jammers can vary from country to country and it is your responsibility to
ensure that you comply with any local legislation.
For your convenience, the GPS Mirror can also integrate with some other
laser-based systems in addition to laser jammers.
