I've gone through all of the threads already in regards to detectors and jammers and I'm finding it all so confusing. Is there a conclusive answer as to what the most effective laser jamming system is? I have an F430 Spider if that makes any difference at all.
Ask any cop and they will give you the answer. The best protection is to stay within 7 mph of the speed limit. Remember just because you didn't get a ticket doesn't mean they didn't know how fast you were going.
Where's the fun in that? Hehehe My jammers have saved me quite a few times where otherwise fun might have cost me my licence, or even my liberty
So if you have a laser jammer and you are going 95 in a 65 zone, what does the cop see on his laser gun, 65, or 0, or 140?
He sees a jammed signal; He'll look at his laser device with a puzzled look and then look carefully at you to decide if he perceives that you are speeding excessively. He knows your car sent a jamming signal, and he now has to deicide what to do. Face it, he pointed it at you because he had already decided you were probably speeding so he's already inclined to believe you are, now he's looking more carefully and making a mental decision about how much over you are going. At that point he can make a personal judgment about his perception of your speed and decide whether pull out, pull you over to ticket or not. In a court of law, more often than not his judgment about your speed will be accepted as informed and valid. For me, the jammer has been not so much useful for jamming my own speed as much as an alert that there is a laser ahead, letting me know that the car in front got lasered, and I should slow down. I can't think of any instance where it actually got me off after 50K miles with one. I have the Passport system, and its cool and gives me plenty of warnings. But I have no allusion that I've gotten off because it jammed a signal. Mostly I get a pass because I wasn't going that much faster than anyone else, and I'm not worth the effort compared to some yokel going way faster.
Here, a cop has to prove the speed, the jammer therefore jams his gun, so he gets an error message, and then stops jamming five seconds later, during which time you had the warning and stamped on the brakes. He then gets a speed reading, ideally at or around the limit. Here, that means he can't prove your speed, so technically can't get you. However, he may still stop me, and will ask why I was stopped. This is the best bit - if I admit I was going too fast, or that he stopped me for speeding, in any phrasology, he gets to stick me on for speeding due to my admission, as he no longer has to prove my speed. If, however, I say 'I have no idea officer, please explain', then in order to prosecute me he MUST PROVE my speed, which he cannot, he can only prove the speed after my jammer shut down, which will be lower. I have enjoyed this fun and games on many many occasions, and have been ticket free throughout. I've been hassled, chased down, threatened and just use a thick skin and polite manner every time, as I know the law requires particular action, regardless of what a cop will say. I've had them tell me they will get me banned, they've turned up at the house claiming they will take the cars unless I cooperate and admit guilt to something, I just refer them to their rules and the law, and walk away In the states, I haven't run a car with laser jammers, so I haven't any experience of trying anything out, so it's interesting to hear that a cops opinion is law. However, I have been caught speeding a lot there and paid some pretty good fines, and avoided jail in Florida just because I was polite I think! (135 in a 65 stretch of highway, fine was around $1000 as I remember with triple fine zones etc, which I'd never considered before)
I am guessing that you're thinking of laser detectors. A laser jammer is a completely different beast, they do work, the cop does not get a speed reading, and it works exactly as Sid described.
Nah, I find Americans and Canadians way more civilised than the average Brit, many are exactly the stereotypical lager lout you see on the telly!
This always comes out to be a 3rd rail discussion. It's like what is the best oil to use. I can't speak for other then NYS and maybe the US but any form of jamming system for radar or laser is illegal in the US. Some states even outlaw radar detectors. My BIL is a retired NYSP officer. All of his cars were equipped with radar and laser speed enforcement equipment. They also have radar detector detectors to see if you have your unit on. They know when/if there are any jamming devices working and will make a decision to either do something like follow and stop you for some dumb law that you or your car violates. We have so many motor vehicle laws that you almost always can be stopped ( no front plate, etc.)for some reason or another. It may be harassment but it is done. If you have a visible jamming device when stopped and it is on it will get confiscated and you get a ticket. In some cases you can also get your car impounded. I don't have a dog in this fight only letting you know what they can and will do. I understand the discussions in the barracks is pretty funny listening to the various stories people come up with. So if their detectors malfunction they assume what the problem is. If they want revenue they would do a tandem speed trap where there are 2 cars spaced maybe a 1/2 mile apart. You slow for the 1st car and they get you with the second. Hey you take your chances so enjoy the drive.I'm only repeating what I hear. My speed is limited to 7 mph over the limit where you are invisible.
It's actually far less ambiguous. From Wiki: Nine states have state laws specifically banning laser jammers: California, Colorado, Illinois, Minnesota, South Carolina, Tennessee, Texas, Utah, and Virginia. Radar detectors are legal in the aforementioned states (Excluding Virginia). But at least in CA and WA, an officer can pull you over for speeding based solely on their own judgement of your speed. They are trained and experienced seeing cars at speed, and their testimony in court is more often than not upheld as to speed. Radar and laser just give one more data point, but are not the only way you can get caught in most states for speeding.
And air. As far as I am aware, in NYS laser jammer is legal. Now it might not win you a lot of favor with the officer who pulls you over, but it is legal. Radar jamming is illegal because radar is a radio signal and that is the jurisdiction of the FCC. The FCC says radar jammers are illegal. That's nationwide. In NYS these things are legal except for vehicles with a weight of 18,000lbs. New York Vehicle and Traffic Law - VAT § 397-a | FindLaw As far as I know the two places radar and laser detectors are illegal are Washington DC and Virginia. Radar detector detector systems work because poorly made radar detectors emit certain signals. The better ones are not detectable at any practical distance. My recommendation is the Escort custom install system- except I think we might see something at CES with an update- and that means maybe 6-7 months from now on the market. If you have to go now, I'd go with the 9500 CI (custom install). My experience is these things do in fact work. But, better than any system, based on over many decades of driving, I think your best way to avoid tickets is to use your eyes and common sense and don't drive like a maniac.
You may or may not find this interesting about NYS: NYS does not recriprocate ticket info or points with any other state. If I get caught in Pa,Ohio or Hawaii you just pay the fine. HOWEVER NYS does recriprocate points/info with Ontario Canada. If you live in NYS when you exit the border the green flag drops unless you are in Ontario. Yes you pay the fine. Have gotten stopped in all of the above plus others except Ontario. Once crossing NE Pa got stopped and the officer said he caught me going 81 in a 65. I said guilty. Paid fine. We did not discuss my actual speed......... GTS Bruce
Succinctly: unaided visual estimation by a trained/certified officer can get you convicted. Spend your money if you wish. But, any officer writing for speed and using any detection method only does so for corroboration of visual estimation, which is based on training and requires certification. While they make for an easier prosecution, aides such as radar/lidar/vascar/etc are not requisite.
