Do RADAR and/or LIDAR Jammers really work?

I have seen some products and reviews stating that some of these do work. I would like to know if anyone has any personal experience with any of these units or others or evidence confirming or defeating the tests that suggest they are effective.

I realize that many people have strong opinions on the topic of speeding and risking others well being but there is a discussion already started for that topic so please lets keep to the actual products themselves which is the topic of this discussion. I am not suggesting anyone speed in such a manner to expose others to unnecessary risk or danger.

One test I found that included among it the BLINDER MODEL M27 and M47 as well as the ESCORT MODEL ZR4 is included here for anyone to read and comment on to begin.

Check your local laws. Jamming radar is illegal everywhere, I believe, and can get you in big trouble, since radar is a radio frequency regulated by the FCC, and there may be local laws as well. The radar "jammers" you see for sale, if they are actually active jammers and not some passive device, are strictly illegal. Also, you're usually buying plans, not an actual device, since the device is illegal and the plans are not, so it would depend how adept you are at assembling complex electronics. Most of the passive devices simply don't work, and are a waste of money. Lidar is optical, so it's not FCC regulated, and not illegal in that respect, but once again local laws may say otherwise. I personally think jamming radar/lidar is foolish and risky, because if your car is the only one they can't get a lock on, they might come after you anyway to see why. I've seen active jammers demonstrated where you can actually dial in a speed, but it was pointed out if you blow by a cop at 70 and his radar unit says 55, he might want to see what's so special about your car.

I don't even own a radar detector, I am just interested in the equipment and the validity of the tests published. I am aware of those devices you mention which alter the signal of what actual speed is, I am not confident in their ability to do that though from what I have read. However I am not talking about those devices but the ones such as mentioned in the article tested from Blinder and Escort etc.. I am not prepared to accept the review of just one source, especially one that sells the products, but it is a start.

I know that at least one of the units has a button so that when one gets an alert that they are being targeted for speed they can press that button after slowing down allowing for the person measuring speed to get a true readout eventually. Not sure how these work in actual practice.

Again I don't have a detector or any speeding tickets on my record so I am not necessarily going to purchase a detector or jammer myself. I have avoided getting tickets by not speeding around other vehicles which also means not risking anyone else when I do speed. I do find the products interesting though and would like to know how accurate the reviews of those products are.

I am aware of various laws for different classes of lasers as that is a hobby of mine but not how they relate to being "jammed" or used in this capacity. It would be interesting to know about specific laws for radar and lidar detectors and jammers, though of course those vary according to jurisdiction save for any Federal laws.

Almost all radar units now in use are the "instant-on" type that don't put out any signal until the cop actually pulls the trigger. While there are radar detector that can detect the residual signals very close, you're really relying on picking up the signals from OTHER people being targeted as a warning. If you're in a remote area without much traffic, there might not be a warning. Modern radar guns also track more than one car at once, and randomly shift their frequencies too. If it's lidar, there is no way to detect it till it's on, so unless you pick up a stray beam from somebody ahead of you getting read, once again there may be no warning. I have certainly never tested any of these devices, but I know that modern equipment is a lot harder to fool than the old stuff was.

Jamming RADAR is a federal felony offense with a punishment of a fine up to $50,000 and or imprisonment up to five (5) years. There are several good active laser jammers that do work very well at jamming police lidar and there are no federal laws prohibiting their use.

However several states such as California, Colorado, Illinois, Oklahoma, Minnesota, Nebraska, Utah, Virginia, and Washington DC have passed their own laws prohibiting their use.

Well I don't know if I will be getting any product but if I do sounds like the LIDAR jammers are the way to go (at least in my State right now) along with a good RADAR detector with the options mentioned here if one is going to try to get this sort of equipment. I still plan to keep the same driving habits which have kept me from getting any tickets for well over a decade (can't recall the last one I got it was so long ago) so spending the money may not be something I am willing to fork out. The jamming units I have seen are not easily transferable from vehicle to vehicle either which would also be an issue for me. It is good to know what is available and what works and does not and what is legal though, especially serious fines such as mentioned which are far worse than any speeding ticket I can think of.

I speed all the time, regularly over 100 MPH and I never worry about tickets.

I think you have an advantage I am lacking there Carl :)

Paramedics (me, and problay Carl) can get away with it!

Yup, those "secret squirrel decoder rings" can work wonders if one is caught speeding huh?

Some wrecker drivers think they can get away with it too. One night I had to chase one down in heavy traffic that was going 105/50. Besides receiving a citation for the speed, his information was turned over to the division that has authority over wreckers and his permit was suspended for 90 days.

I don't know that I would get hired at this point in my life to be honest. Though I really considered that when I was younger. I had checked out both local and State and various requirements for all of them. Maybe if I lived in Texas and had the support of a friend with influence perhaps that would help things.
I think it would be an interesting and rewarding job though. If I thought it were possible I would more than likely do it.

TXDPS used to have a maximum entry age but it was lifted. If you can make it through the academy, you got it made. I think the oldest recruit so far has been a guy in his early fifties.

i had, 24 years ago, a radar jammer.. it used to set off all the detectors around me.. got pulled over once with another fellow doing a good 80 in a 65 zone on the interstate..
cop chatted with me while the other guy waited.. let me go.. i don't know, for sure, why..

100 + is just plain stupid.. too much can happen too fast unless you're on a wide open interstate at 3 am then maybe if your car is built for it..
mine usually are.. SL600, S600 and an E320 wagon..
i use a valentine one and while doing 85 in NC in front of a pack got a signal, tapped the brake to get off cruise control and rolled back to 80 in a 75, rounded a bend in the interstate and 5 cops pulled over more than 5 drivers but not me.. don't know why but my guess is they had the lady in the lexus just behind me at 85 and me at 80 and picked her.. too bad she was a courteous and steady driver who had been near me for over 100 miles..
i also use a black box video dash cam, gps etc recorder for those times, if ever, the s..t that hits the fan gets on me.. if i'm in the right i have evidence and if not i'll lose the camera.. :-)

overall, my point is, good steady driving will get you there safely and thats all anyone should want..
but be prepared for a speed trap and the above mentioned fan..

save the racing for the drag strip..

I think that is a problem with some drivers. They assume because their vehicle is capable of going fast that they as drivers have the training and experience to do so. This is simply not true no matter how common this delusion is. Also once you get up to a very high speed in anything save for a race vehicle prepped for it and a track set up for it the results of the crash is going to be very unhappy.
I try not to do my high speed driving when there are other vehicles around at least. II have experience and training and vehicles very capable of going up in to the upper triple digits, still guess what? I am still capable of crashing. Better racers than me do it all the time in even more competent vehicles and in much more controlled environments.
Not sure that 3am is a prime time for speeding on the interstate, this is the drunk watch in most places.

I do like your video cam though. I have thought about that myself, perhaps also a video cam with audio in the interior too. I don't get pulled over hardly ever or encounter anyone, police or otherwise, that I have do something wrong and dirty or lie about things. Still not a bad idea I have just thought about but never implemented. Though it is possible if you have it on during one of your high speed driving experiences it could be used as evidence against you.

Friggin great topic! I still got a need for SPEED. Ever notice how we are being herded into a certified-bonafide-licensed-professionally trained world ? Well I have driven off road cycles and buggies for at least 45 years and wrecked everyone of them! However, driving down a smooth, flat road seems easy but a hipo thinks you are a criminal if you speed. That said, I have been into radar jammers since 1980. The fuzz-Buster was becoming worthless due to the fact the cops were breaking the law by tweaking their radar units to broadcast off issued frequency. I got "the judge" got pulled over a few times when I would pass a cop on a hill going the opposite direction over 80 mph. They never had me on their read-out. Then came Ka instant on (wide band now legally issued w/instant on) that still leaked a radio signal. So I got the "Judge II" with instant on micro switch, worked great. Then comes the "Digital Stalker II" for the highway patrol mostly, expensive. The "Scorpion" now handles these units. However, notice that most coppers hide in speed transition zones, i.e. 75 to 65 or 60-45 that is where I see them with a preponderance of Lidar. Then on the far side of curves and over hills waiting for you to roar over the hill at 85 mph. Why they hide there is to avoid visibilty by motorist but also cause their radar is a blunderbuss spouting radio frequency out in a 55 degree arch (why they are defeated in court and Lidar exists now) so pointed up a hill or off of a curve your radar detector is WAY LESS effective. However most cops can't resist the urge to speed check everyone and therein lies my desire to have the latest best "Bell" radar detector that still gets the signal. Also you want a anti radar detector detector, most cops can know if you got a radar detector onboard, the Digital Stalker II comes standard with a radar detector detector in it, (used or rationalized to detect if a 18 wheeler is using a detector). I never speed when alone, always overtaking another car especially at night! Also, get a CB radio and monitor trucker talk, it still works great!!!!!!!!

Well oine needs to decide do you only want to know where a cop is with a radar gun or a cop is period ? I like to know wer they are Period eatin lunch sittin in park watchin folks etc Some Mfgs Make devices that hone in on I believe the trunk signal which is a signal always bouncing bck n forth from car to tower n bck to keep track of officer n car equip etc.. Youre in police State/ country A officer needs Not have a Radar to have a street interview with yous .. all they need is to be around with nuttin to do and see an interesting bumper sticker and its on Naw theyre not going to mention the bumper sticker they gonna discuss other things tyres exhaust oh by the way your car smells funny Id like to look inside No well Ima call in a dog sniff Etc No wer the Officers Are if they behind you pull in the store etc get em off ya now Ive worked with Military intel in many countries Youd be shocked at how your rights being trampled Lawyers cannot help theyre in it to.. Look at DUI laws the arresting common folks on normal medication and giving DUI's theyres no legal dialouge they stick and cost you You voted the crap in

Yikes, tomD3..

First off, your language is, well, somewhat lacking, but then i'm no typist either, so we'll just pass on that..

and i was going to pooh pooh your entire post until the last lines about the DUI stuff..
having a good friend who just ran afoul of a DUI trap i can personally attest to and agree with what you say..
she was on meds and was pulled over and passed the "walk the line, now balance on your toes for 10 minutes and was about to be cut loose when a badge heavy seargeant drove up and told the other officer to arrest her because she started balancing on her toes a second before he said to start..
no take the test over, just jail and thousands in fines, fees and such in a miscarriage of (IN)justice..

and there ARE traps on the interstates when some canine units pull you over and then have their dog trained to "alarm" on their command and thus now you're in trouble when the same canine office plants some grass or similar in your car..

SO, you bet i want to know when the police are about and catching their "carrier" wave transmissions is a d@mn good way to know that..

forewarned is forearmed or something.. :-)

which is why two of my three cars have valentine one radar detectors AND blackbox cameras that take a video and sound recording along with GPS speed and position and record all the time while the car is being driven.. for evidence against bad drivers and dishonest police..

who was it who said "if you give up liberty for security you will wind up with neither liberty OR security"..

the parasite class has voted for security and will be surprised when they find they have now lost their liberty AND security for a police state, forever..

thanks for the ideas about the carrier waves..

Gas costs too much to speed plus its unnecessary wear and tear on the engine too. I prefer to just chug along and draft behind the semi's. Why speed to get somewhere 5 to 30 minutes faster? Im always 20 mins early to work so I can BS, smoke and drink coffee before clocking in. Its always the young guys walking in at the last minute to clock in. I bet they drove like maniacs too. I was young once too but never did it and 49 yrs later still no tickets.
Its a young mans game I guess.
