The Snooper SLD920 is high quality product manufactured in aluminium, easy to mount and easily serviced and Costs £299.95 This twin transmitter, twin detector combined unit comes standard with two IR. diode arrays and a laser detector in each IR. head. A miniature buzzer supplied can be installed inside the vehicle, and provides the audible alarm each time one of the detector heads are hit by the laser beam of a police laser gun.

They claim that the unit offers:

  • Complete protection against all laser guns and fotolaser traps. The IR Detectors transmit the incoming laser pulse frequency to the computer. The computer calculates the optimal jamming pulse (APS) for the eight specially manufactured IR. jamming LED's in each head.
  • Automatic pulse selection for the optimal infrared jamming shield and because the jamming pulse only is transmitted in a fraction of a second, it has become possible to apply an extremely powerful returning jamming pulse signal.
  • Detection of the laser gun and Laser Warning Alert. The laser warning system (LWS) tells the driver, that a laser gun is operating near him

So did it work...... ?

With our boot load of Laser guns, don't ask, it not easy buying this stuff, we had to tell a few lies and spend quite a few quid, but it is possible to own your own speed detection gun.

Off to a nice quiet straight road, after all we did not want to attract too much attention, did we? We did the test by using the four main Laser Guns used in the UK, the LTI 20-20, Riegl LR 90, UltraLite LR and Prolaser II

We then drove our test car towards the guns in turn doing several runs, we targeted the number plate and as many other parts of the cars as possible at ranges of over half a mile, so far in fact it was hard to spot the car in the sights of the guns.

All the guns had a real problem they all showed errors, the LTI went through almost all the errors it could find, none could get a speed and only some could get a distance, even at 20ft the guns could not get a speed reading, not only that, but it DID NOT bring up the LTI's Jammer indicator. Now that's very smart!

I was impressed, very impressed, I have tested other jammers and they never worked or if they did it was only on some of the readings they managed to jam the guns. The Snooper SLD920 however did what they said it would do. It's a well made piece of kit, it looks good, and is made in a tough aluminium case, it came over as a high quality product, unlike the others.

So what's like in the car, well is gets rather noisy with it's warning system going, you get plenty of time to slow down at your own speed to the legal limit and then turn off the system as you continue to drive towards that rather confused copper... you could even give him time to get a speed reading of your car at the legal limit after the jammer is switched off to remove some of the suspicion.

The twin heads in this case were mounted in the grill and were not easy to spot without knowing what you were looking for.

between the number plate and the outer lights.
