Jammers are most definitly on the wrong side of the law now.
I would not fit one to any vehicle, personally, as the ramifications of prosecution for one of the two possible offences are significant. Whereas getting caught a bit over the limit nets 3pts £60. Even getting caught well over it is only 6pts and a few hundred quid. Nothing in comparison.
If you are going to bother with "countermeasures" I suggest a Sat Nav system with a camera/mobile database. I use a free one. Its helpful.

Sorry, meant laser jammer (as LT400, LCR100), not radar.
Although one of those white noise devices as used by the Special Ops helicopter in Dan Brown's Deception point would be handy. It jams every communication for a 1/2 mile radius. Should work in all cases. (shame its fiction!).
Radio reception wouldn't be too good though!

And surely that is what speed cameras are for to slow cars down?
Excellent practice of yours, if only that was the policy, to slow cars down instead of just trying to catch speeding motorists.
If the policy is just to slow cars down then why not put some of the money earnt into putting up some speed limit signs. (could this be entrapment with out them?!!)
Especially on speed cameras, how many times do people see speed cameras and then look at speedo and say "whats the limit" only to find there are no speed limit signs around anyway!

Can I suggest raised vision...its free and most of us don't hide so if you look ahead you will see our car.
Also don't waste money on laser detectors. Our latest bit of kit Prolaser 3, fires and reads 3 lasers a second, so imagine the scene, you are driving down the road, beep beep goes your detector device, your brain goes sh*t rozzers must engage brake as i'm speeding, by the time brain, foot, pedal, braking system work together the laser has got you several times.
But can you trust the speed reading - when they're not giving an error code? See the "lasers meters are innacurate" thread.
DustyC said:Some do, some don’t. Some have a limited operating range.
Do they work?
DustyC said:Yes. Lidar guns use special algorithms to detect such countermeasures.
Do they draw more attention due to error signals on speed guns?
Some jammers allegedly won’t even generate error messages, but a speed will still not be displayed. This is enough to prompt the operator to flag you car on their database. Your car may be subjected to a late night examination if you accumulate too many of these flags.
DustyC said:Strangely enough: no, unless the offenders aren’t admitting it.
Are there a lot of cases against people using these devices?
The smarter users don’t rely upon their jammers; they keep them switched off whenever possible.

Any specifications?

Would have thought that a must. Since the GPS devices these conect to can determine when you are driving under the speed limit can they not automatically disconnect the jammer?
DustyC said:Here’s a great review site: www.ukspeedtraps.co.uk/index.htm
Any specifications?
Hover the mouse over ‘product reviews’ then ‘Jammer reviews’ for a list.
DustyC said:I don’t know of any commercially available GPS based device which will set an output when it’s in a vehicle which is exceeding the posted limit for that road. Even if such devices do exist they still won’t give you adequate protection; mobile sites are setup where drivers are most likely to (safely) exceed the limit.

I thought no speed limit signs plus even street lamps = 30
NSL country roads dont get repeaters either...
I didnt have time to measure the distance between the street lamps to ensure they were even. Plus I was going much too fast anyway, they were all just a blur.
(Well, thats if it had been me).

Now if you had one of those garage door opener devices you could configure it to bounce beams between the lampposts to calc the distance between them

But if your out one early morning on a lovely fast A road, maybe 120/130ish (shock horror, but we do it) & you get zapped but the jammer prevents a speed reading, if you then take out the jammer when you get home & lock the car away in the garage, the £250 paid seems very good value compared to the definate ban poss worse you would have had.
Plus its a mans right to protect his licence!

The only answer I have to that James is what museum did the BBC get that antique from ?
The only laser to be seen on the street with is....
Calibration sticker on side of laser, certificate will be produced at court, etc etc....
Listen give me a break I'm one of the good guys !!
Hi,
Can I ask, what would be the maximum distance you would use the above from the target, without a tripod?
Whilst I realise you are one of the good guys, I am interested on your viewpoint on how accurate the devices are. We have heard that if slip error is present that the device gives an error reading.
If that is the case, then in theory, if you were to be targeting an object with no flat areas, say a circular football (moving of course) then some degree of slip error physically must be present as it would be impossible to keep the target position exactly the same for the third of a second needed to get a reading.
Would the device give a 'slip error' reading under these conditions?
Cheers.

...basically what you point at that is moving you get a speed.
Hi,
Thanks for responding. It is something I am interested in personally after a lot of research. Your quote above is one I have heard before, but is it really that easy? For example, if you do not follow the ACPO guidelines, can you still be sure of the result?
I have heard of the pen one too, its from an internet 'defend your self at court' type document, I was interested to find that people actually use it!
I am also interested to hear about what you think of by football hypothesis, if the device rejects results which include slip error, surely it must resurn an error message if you tried to take a reading from a moving football?
Cheers again, not trying to grill you, just get an idea of how the devies are used in the real world, as I have never had the pleasure myself!
Having used & tested many of the above mentioned devices & from owning one too, there is a HUGE difference in the abilities of some to give erronous slip readings.
The Prolaser I II & III are certainly better than their counterparts. There is one device thats even worse than the 20-20 for giving completely spurious readings & you don't have to try very hard!! & its UK type approved, I don't know how frequently its used though in the UK & I've forgotten its name right now, but it looks similar to the Prolaser III.
