Default laser jammers

i have a Valentine 1 and love it, but due to the amount of highway driving i do and the amount of lead foot i have, i've been looking into getting a laser jammer. the V1 tells you when you get hit with laser and is kinda a nice notification that you're already screwed. does anybody have a laser jammer and if so, is it worth it? what type/brand do you have? thanks for the help.

Seems to me, if laser jammers worked effectively, communities whose law enforcement agencies used laser detectors for traffic enforcement would outlaw the use of them. It would be very easy to identify a car with a jammer equipped and give that driver a ticket for having it.

Car and driver did an article about this once, and the most effective "jammer" was to have a crapload of wide beam light output on the front of your car, while also minimizing any flat surfaces (such as a front plate).

If I remember correctly one of the subjects was actually a regular lt1 style firebird, and that car without a front plate was very hard to lock with laser because there were no flats to speak of.

A little off topic but that's what I recall. Don't use a front plate if you don't have to, and you'll (in one of our cars) be a lot harder to peg than 95% of the cars on the road.

If you have to use a front plate then some sort of nonreflective coating would probably be more effective than any electronic jammer sold online.

And if you are ridiculously dedicated some arrangement of very high powered driving lights or perhaps even modified DRL's with filters can actually be an active solution.

Laser jammers are illegal in some states. Here's a list:
http://www.guysoflidar.com/faq.html#3

As far as the best performer, currently it is the "Antilaser" which is sold as the "Laser Pro Park" by a company called KMPH out of the UK. It is marketed as a "parking sensor" , but it just happens to also jam police laser, and very well at that. Oh yeah, it will also help you park your car Great for people who live where jammers are outlawed, but parking sensors are not.

My second choice would be the "Blinder". It provides decent performance for the price, and has a proven track record. The Escort/Beltronics jammers such as the Shifter ZR-3 are also good choices, but they do have trouble with certain guns.

Check out the test results at http://www.guysoflidar.com, we get together and test this stuff out every few months or so...

Does anyone have a link or know of stuff to spray on your front licence plate to make it harder for a radar gun to get a reading.

There is nothing that can be sprayed on to effectively prevent RADAR readings. What they were talking about was LIDAR (laser) which is light-based so it can be diffused to reduce reflections. RADAR is microwave (like radio) so it can't be diffused by any coating you can get (unless you steal some from the military ).

Theres also paint which is intended to be sprayed on your license plate due to speeding cameras (it makes the license plate un-readable in the pictures supposedly)... Ive thought about trying it.

There was a report about that on one of those news shows on TV. They found that although the coating blurred the license plate numbers for the cameras it wasn't enough. The sophisticated image enhancement software available today (and used by police departments that are into technology like traffic cameras) could always read the number.

yes, I have read too that there's no protection against laser technology. There was a test by a company that tried all the laser deterant devices on the market. None worked effectively.

I believe the test was done by 20/20 or dateline.

If you have to use a front plate
You still don't have to mount it at a 90 degree angle to the ground, just mount it leaning forward 30 or 40 degrees, it looks nearly as tall from straight on, but at a slight angle it virtually disappears, and at large angles from the front it does disappear. I mounted the plate on my Beretta like this for a time by putting the screw through the upper holes in the plate into the lower holes for the brackets (tucked back under the bumper a few inches), but I was worried about it falling off because it's not a perfect fit, so when I have some more time, I'll modify the bracket or bend some aluminum and drill two holes to make what I need.

If you don't like it on the front at all, just put it on the passenger side dash, up against the bottom of the windshield, and put something under it like a rag or a small piece of wood to hold it flush so it doesn't rattle.

Both of these have been proven legal to me because I have driven by cops at least 50 or 60 times since I mounted it at an angle, and since I put it in the dash, and none of them were even looking at me, let alone pulling me over, including an area of the nearby city reputed to have the strictest/worst cops in the eastern part of the state.

Soo.....biased and worthless?

Not entirely. While it is true that there is nothing you can do that will totally prevent LIDAR (laser) from getting a reading, you can delay that reading - hopefully long enough to get your speed down. Most of the tests have been biased to prove whatever the reporter is trying to show.

Laser jammers diffuse the laser beam in such a way as to make it difficult for the gun to get an accurate speed reading. This only works when the source is far enough away that the reflection isn't strong anyway. Once you get close enough the gun is going to get a reading. So, those who want to sell laser jammers demonstrate how well they work by doing their tests at a distance. News/public affairs programs that want to show that they don't work will demonstrate that the approaching car reaches a closer point where the gun gets a reading despite the jammer.

Are they worth the money? Probably not. If the LEO avoids targeting vehicles until they are fairly close then you won't have enough warning to slow down before he gets his reading. They may provide some protection if you are targeted from a distance and are driving in fairly light traffic. Unfortunately, this doesn't happen very often. The cost of the equipment and training for officers means that laser guns are usually deployed where they can get a lot of people quickly - in other words where there is more traffic. This means that they don't need to target at a distance and that when he does target you it will be full on at a shorter range.

This is the part I meant about biased, you got it.

exactly what they said, if your close enough, it will get a positive read everytime. Or basically busted.

laser jamers are marketing in my opinion. A radar detector can detect a laser beam. A jamer is only delaying, not preventing. That's why I said marketing, they want you to believe you that the beam will not give a reading, it's simply not true.

Click here to see Video

I hope this is the correct link. I am at work and I can't download the player for streetfire. If this is the one I think it is, they are trying to running lidar on a corvette that has a jammer on it and the jammer works awesome. It looks real to me. Hopefully this is the right one. It is on www.streetfire.net under videos and the cops section.

No, they send back lots of laser signals to confuse it. Diffusing would be veil. LPP can get JTG (jammed to gun) performance fairly often, and they can't get a reading if they're shooting your side, but unless you've got jammer heads in the back, they'll just get you when you pass them if you haven't slowed down (hopefully you have by then, though)

looks like theres a lot of misinformation in this thread

heres what http://www.speedlabs.com/ has to say about jamming http://www.speedlabs.com/radar_laser_jammers.html

and heres Speedlabs radar reviews http://www.speedzones.com/

you can also go to http://www.radarbusters.com/ for what can be a biast report (sells the product), but he still does a good job.

as for mythbusters, they never evaluated lidar (lazer) against 920nm lighting or lazer diodes.
