Hi,
Has anybody installed a Laser Star laser jammer/parking sensor?
Is it any good?
Any issues with them?

I haven't as they are illegal. Whether you're likely to get caught using one I have no idea.

I do use a Snooper 3zero which has GPS, laser & radar detection. The laser detection is quite good, so long as you are following someone else so they get pinged first.... you won't catch any laser scatter until the rozzers fire their equipment at someone :-)

So, laser detectors work, but make sure you egg on a scooby to race along in front of you so he gets the good news in the post

I thought they were illegal aswell. As far as I am aware it is now only gps type detectors which are legal to use now.


The laser park system is legal as long as you are using it for the purpose it is 'designed' for, do you really need to have it active when your tanking it around, I dont think so and I'll bet you'll have a hard time trying to explain why you do.

There is another device which uses a laser transmitter to open garage doors or switch on driveway lights. Which I would guess does need to active. I remember reading an article somewhere about a police officer checking traffic with a gun and found he got a false/jammed signal from a car. He noted it down and two weeks later got the same result from the same car, so they went to the owners house to investigate. It turned out that he had no additional devices which the laser could operate to legitimise his need to have such a laser device and so was prosecuted.

Hmmm, I've got a "friend" who has 2!
One on his car and one on his van, he's not been zapped yet to test them, but they are switchable and act as a distance sensor for the front of the vehicle so he would have to leave them on just in case. All of the above articles are pretty old so I wonder if the police are finding it more difficult to prosicute due to a specific ruling

Anything that interferes with the laser signal the police are using is potentially (has to be brought to court) illegal under the Wireless and Telegraphy Act. Merely detecting the signals is not illegal.

There were movements to get laser/radar detectors banned in recent amendments to the Road Traffic Act, but they never got through parliament. They are however illegal in many European countries, and in some countries are even illegal to possess, so be careful if driving off in to Europe with one on your dashboard!

What's the point of a detector anyway? Unless you can detect the specular reflections from a vehicle which is being pinged in front of you - unlikely, since the reflections will go back towards the laser - then you can't see it unless it hits you, and you for sure can't outbrake the return pulse.

Recall that the police are not allowed to measure your speed on an ad-hoc basis - they must have reason to believe that you exceeding the limit before they test you.

And to be honest; the best laser jammer is under your right foot.

(Now, the way to jam a sensor is not to just blast it. The *subtle* way is to send back to the receiver the signal it expects to see, but subtly delayed such that your apparent approach speed is at the limit... of course, that means you have to avoid reflection of the initial beam, but there are some new stealth materials out there. I wonder if that's why the ridiculous matt black look is now fashionable?)

I used to have a good one on my last coupe and it worked at least twice. it was an lti I and I sold it to a member on here (I won't mention his name)

My current coupe has a "parking sensor" on it which I have less faith in. I don't use it as a substitute for responsible driving it's just there as a safety net incase I slip up in front of a laser speed trap, er, I mean whilst parking.

That's OK stinky, it was me, remember? I've only ever had it go off early in the morning when driving into the rising sun low on the horizon, maybe that's why all the sun spots disappered a few years ago?

Oh Noes! Dave jammed the sun! We're all going to die!

I'm not sure how effective a laser jammer costing £169 will be, I work with laser jammers costing, well you won't get any change from a 2 million pound note and there's a fair amount of technology and size involved.

There may be something in it but i'm just very skeptical.

Jimbo, can you just point one of yours at the sun and see what happens?

S: can you scan a picture of one of them notes? I've been told that £50 notes exist, but I've never had one spat out of a cash point at me, and I've never had £2m in my account just so I could withdraw it one day...

Tried that last week and look what happened.... it fired back at us!

Yes that's exactly what I thought had happened

Speed cameras and laser jammers! I love them. Telling fake cameras from real ones is my speciality. I often speed past them knowing they are fake, with people in the car going crazy telling me to slow down. Brilliant!


Back to jammers:
They do work..... and they are NOT ILLEGAL having one... the offence you would be prosecuted for though, would be perverting the course of justice.... (which also carries a prison sentence)

One of the best sites out there is http://www.ukspeedtraps.co.uk/

I had a Snooper 920X up until a few years ago. The idea is simple, it is not set to 'JAMMING' permamnently. Once a laser would be detected by the rozzers, the system would jam for a pre determined time (a few seconds), in which time you would be alerted and brake... then it would switch off.
By this point you would be at a sensible speed and the rozzers would merely think the 1st attempt of the laser bounced off the car... which can happen!

However, the rozzers also get Error codes on the display screen of the gun. I have read that depending on the device, some error codes the guns produce after being jammed are the same as if they have just missed their target, so the police never know! But then the other side of the coin, some error codes are put straight down to a Jamming device.


It is very rare for the police to go through the courts to prosecute someone for having one. After all, they need to prove it beyond doubt that it's what you're using it for, which is quite hard! But it DOES happen, there is the odd interesting story on the website above.

It is also very unlikely they will ever find you but it depends on the situation and what setup is being used by the police.

A Taliban van at the side of the road, would capture a picture of your car with an error when they cannot detect your speed. BUT THEY CANNOT DO ANYTHING FROM THIS SINGLE INCIDENT to charge you.
I have heard of stories where different county camera partnerships group their photos together to try to determine if it has happened multiple times, which would SUGGEST that they are jamming the laser, and you would then get a knock at the door, with a car inspection.

Worst case would be for it to come from a gun at one end of the road and get pulled by a car a few miles down, for the cop getting an error.


I have also tested my device with real guns, and it was a great day out!!!
I used the LTI 20-20 laser gun (Most popular) and a few others. A company in Leicester actually own these guns and can either rent them out, or simply do a test for your device.

If you are really worried about getting caught, then the only 'safer' option is to get the parking sensor/parking light.
You then have a fairly legitimate reason for having a jammer fitted to your car. One type is a parking sensor, the other turns lights on at your property when you get home. The difference with this is it only turns on for YOUR car, as it talks to the laser. The bonus is, it blocks police guns at the same time.

I dont remember what the question was now.. but rant over. Any questions about anything, PM me

Interesting post, however a close relative (wife's side) is a Sergeant with Essex Traffic, (He was even on Police Interceptors), I have discussed jammers with him and he said.

Laser guns have video camera on them. So if there is an error, the video is still captured, this will have your index plate. From video they can use a process similar to VASCAR to judge your speed, (Measure time between two fixed objects), this would not be used to prosecute you though it will give them an idea of how fast you are travelling.

IF their suspicions are aroused, (And if video shows you travelling at more than speed limit by a significant margin) then they "May" decide to visit the registered keeper's address and get car inspected.

Should they find a device intended to avoid detection/prosecution then they would prepare a file for CPS.

One thing he did tell me is of a case with a driver who was using one of these, apparently the device showed up as a series of flashes on the video camera. He suggested I point a remote control at a camera and see what happens when I press a button, well try it for yourself!

Now I do not know why, but this "garage opening device" must have been emitting on Infra-Red waveband because it showed up, I am not sure if they all do.

Anyway try it with a remote control.

If you are really worried about getting caught, the only safe option is to drive at a speed within the limit.

Full stop. There is no need, ever, for a detector for speed traps.

Thanks Neil, was about to post exactly the same thing, as I think most people know, but maybe not all, I collect points for a living, at one time for a span of a few years I kept at 9 points constantly and I hadn't had a clean license since I was, well for about 15 years, although its clean now

Do you know what I have done to avoid these points, absolutely nothing, I was speeding, I got caught I took the points, do you know what I could have done, I could have joined Poopipoo, or bought a jammer, or had flip up number plates, or coated them in cling film... but I did none of them, as each time I knew I was in the wrong and had to face up to my actions!

Yea i heard the remote control test. It didnt work for me. I think it depends on how close the particular remote can be to the end of the spectrum where the laser is designed for.


Barnacle.... i agree! What i meant to say was, if you are ever worried about getting caught 'from using a jammer!' then i would recommend a parking sensor.
If you are worried about getting caught for speeding, then indeed do speed limits..... a bit hard in the coupe though! Its too much fun

I know someone who has them fitted and I can confirm they do work, and has not yet been prosecuted.

One of the motoring programs tested several standard detectors (not jammers) and found only a £1500 version worked the best and picked up all detectors including ad-hoc mobile cameras.

Hi Dave, yes I remembered but I didn't want to say.

When I bought that one it was the best on the market. The type I have now I have seen in action and under the circumstances I saw it did a very good job at jamming without throwing up errors + it doubles as a parking sensor and beeps when it gets near to an obstacle, therefore giving me a legitimate reason for having it.

You need to keep the heads clean and scratch free & level.

It's just that it may inadvertently jam a police laser gun, not intentionally of course. But that's one of the things here you see because the police measuring equipment is using a light frequency and unlike radio frequencies they can't be reserved for Police use. anyone can use them depending on what they are using them for. One case in point is that many new cars use an adaptive cruise control system, Nissan and Volvo + others use this system now and it uses front mounted laser that also inadvertently jams police laser guns. The police aren't happy about it but they can't prosecute the owners because they aren't deliberatly jamming the speed guns it's just that their device that has another purpose also interferes with the speed guns.

I'm only aware of one succesful prosecution (that was contested by the accused) for a laser jammer and that was because the guy was taunting the cops by continually speeding past the speed traps.

Bloody great infrared lamps on the front, and an FLIR see-in-the-dark system?

reduce funding to the police then they will have no money for fast cars and laser toys.....Oh the government is already doing it.....

Fantastic facts and information.
Many thanks for all the above, I'll think on it more

These make for interesting reading, it would seem Norfolk is an area to avoid if you are using one. I didn't like the bit where they siezed the bloke's car, had it for a month and even charged him £185 for the low loader that took it away!
