    Default Laser Detection

    I have a question in regards to Laser Detection for Radar Detectors AND Laser Jammers. If you look at the picture below that Chris has done such a good job at representing, you will see the approximate beam width of laser at 500 and 1000 feet. Even at 1000 feet, when laser is aimed at the headlights the beam does not strike the Laser Jammers much less the windsheild where most of us have our detectors. If the beam is only that wide at those distances, how can our detectors pick it up? Better yet, are the jammers going to jam it? This has made be quite nervous and I would love any explations anyone may have. And yes, I have permission from Chris to use this picture in my post

    This picture shows why Outruns RX65 didn't go off and his blinder did. This illustration shows why Veil needs to be used with ANY laser jammer. Most cars don't have the perfect mounting spot. By using Veil and the Laser Shield you reduce the reflection from the laser beam. SML taped the Blinder to the bumper in order to get the best testing performance. All of you should learn something from this. Mounting location is your #1 priority. Keep the jammers within 18" of the headlight and license plate. If this is impossible for your vehicle get Veil and the laser shield from radarbusters.com

    Keep in mind the wobble factor and what I mean by this is the majority of the LEO's operating laser devices are not on a rock solid rest and at a distance of a 1,000 + feet it doesn't take much of a movement to make a 18" beam much larger.

    Think of it like this say a sharp shooter with a high powered rifle goes to the target range sets his weapon on a rock solid bench and fires five rounds at 200yds he should get a fairly solid/accurate group now if he's stands up and fire's another five rounds they are going to be more scattered due to the fact he's standing and not on a solid rest.

    So, i'm relying on the shakyness of the officer in order to detect the laser beam? I know what you mean, however, hoping the officer has a wobbly hand seems a bit risky to me. My jammer heads are EXACTLY where Chris's are on his car. The Eclipse has horrible mounting areas as well.

    Is there a potential that he could shoot my headlight and my detecter AND jammer would not alert? This is what I'm kinda worried about.

    I wouldn't lose a whole lot of sleep over it. If you look at any of the jammer test videos where the camera is looking through the laser gun, at 1000 feet, you're not aiming for a headlight or plate, you're aiming for a car.

    Though that's a great depiction of what's going on, I think that there is a bit more to it. The red circles are the bulk of the beam. This is where the beam is strong enough to illuminate objects. Outside of that fairly sharp cutoff in power there are "fragments" that, while weak, are still visible to a sensitive enough detector. Some can see this, some can not.

    I think it was happya$$ who posted a short video of a trooper shooting laser from the median. (This was a couple months ago.) On it you could see a small point of light emanating from the gun just prior to his alert and again during the alert. No doubt the officer wasn't shooting directly at the camera. However, the CCD was still able to pick up the IR "glow" from the lidar gun's optics.

    I am not sure if you have ever looked through any type of laser gun before but at a 1,000+ feet the only way the beam is not going to spread open at least a little due to shaking is if it is on a solid mount like a tripod or something and I don't think to many LEO's use them

    Ad some veil I'd say you'd almost be bullet proof then.

    Unfortuantly I have never been able to look through a laser gun before, but I do understand what everyone is saying. I guess I just got a little over paranoid and wanted some explanation, which so far, you guys have provided.

    I agree with the wobble factor. If your jammers are near the bottom of the car like mine you're going to have punch through on the headlights. I experienced it with the Laser Mimic and I had the same results with the Blinder. The only way around this is reduce the reflective surfaces by using Veil. I envy the people who have prime mounting locations.

    Is there a chance your Blinder won't go off? I highly doubt it. Your blinder will go off, but at the close range of lets say 400 feet the headlights reflection of the laser beam will over power your laser jammer on the bottom of the car.
