Angry Bel RX65 Pro= Garbage?

I have a Bel RX65 Pro hardwired installed in my M and twice detector has failed to warn me of a supposed clocking of my speed with laser.

The story:
So today I am driving down a four line road and some jerk gets in front of me and slows down ( mind u there were hardly any cars). So I gun the car, look down at my speedo and see that I am at 110 in a 55 mph zone. I slow it down and keep on going my way. Then I ran into a red light, sit there in traffic for a good couple of minutes and then as soon as the light turns green, a cop on a motorcycle pulls up behind me and pulls me over. I think to myself that he is pulling me over for not having a muffler. Since neither my passenger nor I saw any cops on the side of the road; we were sure that it had to be for the noise. Nope: he was "on the opposite side of the road" , despite that we did not see him and that my radar detector Bel RX65 Pro did not go off. This is the second time it happened; about 2 months ago, 52 in a 45. Once again they “clocked” me with a laser gun and my detector did not go off.
BTW: It has gone off before and warned me about laser. Something's not right.

Is my detector faulty, despite that I bought it new?

Has this happened to anyone, with the same or similar radar detector?

Has anyone been able to fight a laser ticket in court successfully?

Is there a way to test out my detector, other than being clocked by a cop?

Sorry to hear. I've had a Velentine for 7 months and the thing works flawlessly. Maybe it has to do with the placement of your detector. Do you have a tinted windshield by any chance?

that sucks bro, it looks like they are spending a lot of money on catching car enthusiasts speeding when they should be looking into other issues, there was a post on here about a new laser that Los Angeles PD is using that is gonna make things really hard to have some innocent fun on the freeway, but then again there are some guys that take it toooooo far..

My Ride: shines like justice
I remember reading that laser detection is a game of chance because its pretty much counting on the light from the laser being refracted from other objects and hopefully into your detector. So not detecting the oncoming officer may be due to the light from the laser refracting from another car but not reaching the detector or maybe there wasnt any other traffic to refract from. Still you'd think of the cop laser'd you, youd at least know it...hmmm. Sorry this really isnt helpful

He never showed the reading, he just held it up and said these things (laser detectors) are accurate, blah, blah, blah.

Sorry for the noobness but, do I have the right to see the screen/reading on the spot?

A detector will only warn you *IF* you are lucky enough to catch a stray reflection as the laser (lidar) is used against another vehicle. Despite many people being enamoured of this concept - the reality is much more harsh. Laser speed measuring devices used by police have a very, very narrow dispersion. At 1,000 feet (and cops never use it at anywhere approaching that range) the "cone" of laser light on your car is 3 feet wide. At a more normal usage of say.... 250-300 feet it is less than 12" wide. This minimizes the chances of catching a "stray reflection". Your speed is measured by a series of light pulses - about 1,000 in one second. A lidar unit only needs 2 pulses to calculate your speed - thus calculating your speed in less than one second from the time the trigger is pulled. The light from the laser gun moves to your car and is reflected back to the unit at a speed of approximately 980 MILLION feet per second. Thats why anyone thinking they can hear the detector , apply the brakes and change the measured speed is so laughable. Add to that the fact that if you are going 100 mph - the chances that there is a car right in front/oblique of you is probably about zero. Cops can see a car thats doing 100 mph and your are going to be his new favorite target - above all others.

Here is a quote from a study of the effectiveness of detectors against LIDAR:

"Speeders ticketed by police using laser devices were four times more likely to have radar detectors than motorists apprehended by officers using conventional radar." (Source: Teed, N.; Lund, A.K.; and Knoblauch, R. 1993. The duration of speed reductions attributable to radar detectors. Accident Analysis and Prevention 25:131-37).

If the cop measured your speed from the rear of your car then there is a good chance your detector never "saw" the lidar. If they measured it from say... 100-200 feet (a distance I often see it used at) then then can accurately aim at your license plate (#1 target) and the beam would be narrow enough that your detector would never see it. I know plenty of people that got laser tickets with a V1 in the car.

Relying on a detector to protect you from laser is very, very ineffective. Once it goes off - chances are 95% the cop already clicked his pen and pulled out the citation book. You cannot out-brake lidar targeted at your car.

At 110 mph you are waaaay deep into reckless driving territory with some potential heavy penalties. I suggest getting a good lawyer.

Nope; here’s a pic of the placement.

A laser detector is worthless. They would be more appropriately called "ticket detectors", because although they may alert you to the fact that you are under lidar scrutiny, you will not have time to adjust your speed.

You do not have the "right" to look at the readout on the gun. Defenses? Two. First, the operation manual for the lidar will advise that the lidar is to be used from a tripod only. Why? Because the lidar pulses to measure so quickly that even a slight movement by the lidar gun may cause the first pulse to measure a different part of the car than the second pulse. Since the lidar needs two pulses needed to measure speed, calculating the difference in reflection time between the first and second pulse, if the first pulse hits a part of the car that is farther from the officer, i.e., the windshield, and the second hits a closer part, i.e., the grille or headlights, the additional three +/- feet is misread as an increase in speed. So the manual requires a tripod for repeatable accuracy from the reading. Will this help you? No, because the officer will say he was targeting the front plate, if you have one, or the headlight if you don't, and will swear there were no errors in aiming.

You would have a better chance of success in defending yourself if you can raise doubt about the issue of identity. I have no idea of the layout of the area where you were stopped, but if the officer was out of the line of sight for a period of time, you can claim it was another vehicle that was speeding, and yours simply resembled the one the officer clocked. Will this work? No, for two reasons: First, no matter the physical layout of the scene, the officer will swear up and down that you were the vehicle that was clocked, because they'd rather lose an arm than a court case (not to offend any LEO here, but you know it's true). Second, the judge will believe the officer anyway, no matter how insane the testimony. Get an attorney. The best you can do for yourself is avoid getting kicked by the kangaroos.

Now for some actually HELPFUL advice. Get a laser "shifter" or "defuser". You can find them online and they are legal in all states but one (but who cares?). They are basically an infrared flashlight mounted on the front of your car that blinds the lidar gun from getting a reading of the reflection of the gun's laser beam. About $500, but worth every penny.

I've had these on my cars for years. In the beginning, the lidar guns couldn't get a reading on me at all, and I could go by and watch them point it at me, then at the ground, fiddle with it, point it at me, then the ground.........LMFAO. Best time ever was one summer when I was cruising +20 over, some a$$hat in a Taurus comes up beside me and (like so many morons) won't pass, but drives right on my quarterpanel so he can speed but not get a ticket. Then I notice Mcycle patro at the side of the road, hidden behind trees on the side of this wide, level, straight six-lane road in the interest of "safety". The officer steps into the middle of the street, and stops us both. Then, he waves me by, and directs the Taurus to pull over. I have to stop at a red light just past the Taurus, and my sunroof's down, so I can hear the a$$hat going nuts and asking the officer why I wasn't stopped since I was ahead. The officer said "I couldn't get a reading on that car, sir, but I did on yours". Needless to say, I have been sold on these devices ever since.

Present day lidar guns are more advanced, and you have to slow down or they'll get you eventually, but the laser shifters can buy you precious time. HTH

As a footnote: The newer lidar units have been developed to be less sensitive to jamming units. That is not to say that your jammer will be ineffective - just that it may be less effective. There is no "sure thing" defense against lidar.

Also remember that your speed can be "estimated" visually by an officer, you can be paced by an unmarked car, observed by an aircraft or timed using VASCAR. Detectors/jamming will do nothing to protect you in these cases.

Are you a retard? 110 in a 55. . You could have killed someone. BTW. . Get a good lawyer jackass.

In our cars you reach those speeds in no time. But then again that's NO excuse. All it takes is a grandparent to turn in front of you and it's all over. But like I said before, I got there in a couple of seconds and slowed down when I saw how fast I was going ; I wasn't driving at a constant speed. Additionally, the road I was driving in had hardly anyone, and it has no intersections for a LONG while.

Apart from my speed ; has anyone encountered this problem before? Most of you on this forum have or had a radar detector at some point.

I have the Bel 995i and it works great... When it comes to Laser and POP you have no chance. The only chance you have is when theres other traffic in front of you that is getting zapped. Radar Detectors are not COP detectors...

Read the detailed post above that explains why your detector didn't go off (and IF your detector did go off - why you would still have gotten the ticket).
