The popularity of laser-jamming devices has virtually skyrocketed lately, since the number of police units that employ LIDAR guns has also seriously increased. And one of the most advanced products of this type is the LE-30 presented by the people over at Lidatek since the second half of 2007, a device which will surely give drivers a fighting chance against all laser-based radars.



The LE-30 employs a Class 1 laser diode for emitting laser pulses (jamming the LIDAR lock), as well as an infrared photodiode with optical and electronic amplifiers for “reading” the signal of the laser radar. In this way, it's capable to detect the “threat” and, in the same time, to neutralize it.



The device from Lidatek operates on the 904 nm wave length and packs an alarm LED, which will instantly inform the driver whenever a LIDAR gun has been detected. However, it also incorporates an alarm speaker, which generates an alarm sound with the intensity of around 97 dbA, quite enough to draw the user's attention.



Another important fact worth mentioning about the LE-30 is that the transponder sports a special, metallic, waterproof casing, which might prove to be a pretty big plus, depending on the location where the device will be placed inside the vehicle.



Depending on the version chosen by the driver (front protection / front and rear protection), the Lidatek LE-30 can be purchased for around 400 or 600 US dollars respectively. These might seem to be some pretty high sums at a first sight, but one has to take into account the fact that, beside the devices themselves, they'll also get the interface box, alarm speaker, system switch, a bubble level, harness wiring, the necessary mounting hardware and, pretty much as expected, all the necessary installation instructions.
