This past Saturday night I was riding along with my friend and we stopped at a red, took a right into a 30 mph zone and approximately 100 yards in front of the car on the right side of the road was a police cruiser. Needless to say, we were pulled over (doin' 45 according to Officer Revenue...) The V1 did not go off, and get this, the cop would not show us the LIDAR gun reading! He said, "I usually do but I was just getting set up and by now the gun has 'reset'..." Now granted, I would guess that just possibly the V1 may have been outside the gun's beam at that range (it was mounted just below the rearview mirror), but, that tied with the fact that he refused to show us the reading seems fishy hmmm . I think he eyeballed us/our speed and didn't realize we had a laser detector until after he said he used LIDAR.

I seriously doubt that LIDAR guns "reset" without the cop's input.

Anyone know offhand the approximate LIDAR beam width at that range (figure maybe two vertical feet from license plate to mount position).

Do the guns reset? Or was he full of it as suspect?

I told him to fight the ticket.

I'm curious as to what you all think about this situation or if anyone has had a similar experience/suggestions and what he/she did about it and how it turned out. Glad it wasn't me...:D

Jutty :cheers:

LIDAR needs to be unubstructed but not a lidar detector. First a cop doesn't have to show you the reading, period amen end of story. Also a cop's visual estimate of speed is plenty to hold up in court when fighting a ticket. YYMV but here in NYC you are screwed without a lawyer, cop wrote my plate down wrong I fought ticket, guilty even with proof that my plate was written down wrong. Sucked

Several times, my up-high-on-the-winshield-mounted V1 failed to detect Laser that my grill-mounted Lidatek "saw". I attribute this to the cop having a very good and steady "aim" at the grill area.

Jutty:

Some of Drew's information is contrary to my experience with law enforcement, courts and tickets. It could be that laws vary greatly between Oregon and NY but I also advise you to hire a good, well known traffic offence attorney and to fight this one. (Chances are about 50% that if you plead not guilty at your premiminary hearing the officer will not even show up at your court date - especially with poor - or no - solid evidence against you.)

Derek

Also, doesn't your V1 go off when you're hit with LIDAR?

Recommend you/your friend contact/join the National Motorists Assn for assistance in challenging the ticket. They can answer your questions or direct you to someone who can. Visit their website for further info. Well worth the small price to join.

Although the V1 has laser detection to the front and rear, it may not pick up that you are being hit with a laser gun unless the laser gun is aimed at a spot near where you have your V1. The beam is much more precise than radar and therefore if aimed at your front or rear license plates (favorite aiming points because most states plates now have a reflective surface) it will not be detected. Or if detected it will be too late. Same is true if using X50 or BEL radar detector w/laser detection.

A M5board sponsor is Lidatek and their LE-30 laser detector/jammer is designed to assist you in avoiding a speeding ticket via laser. Recommend you visit their website for further info.

I understand your theory - and can mentally agree with it - but I run V1 and Lidatek together and have never had my V1 (mounted by my rear-view mirror) not go off when my Lidatek (mounted by my front plate) was activated. What do you make of that?

Poor aim.

All joking aside I think (know) at distance it is very difficult to hold the beam dead steady.

No joke. The first time the cop was resting his gun on the hood of the patrol car. The other time he was standing alongside the road, resting the gun on a tree. Any hunter or shooter worth his salt will tell you to always seek a rest, only shooting freehand when absolutely necessary... unless you're using a scattergun, of course.

Edit: You are correct about range. Both cases were only a couple hundred yards, where the beam hadn't had much of a chance to spread out.

This does sound suspect, and I would fight it, BUT....

...I would not attempt to argue his account ("it reset") against yours. You will lose. I'd get a traffic attorney to work the cause on legal/technical merits.

I got popped on I-85/75 in Atlanta from WAYYYYY long distance. I crested a hill approaching the I-20 interchange and could see a revenue officer splayed across the roof of an unmarked Crown Vic AT LEAST 1000 yards away, across six lanes of traffic. I knew what he was up to and I slowed, but could see him folding back into the cruiser as I passed. A few minutes later, I'm pulled over against the concrete divider, and he's writing me up for 85/55.

On the notes section of the citation, he listed 384' next to the measured speed. By the time I was within 1000 feet of this guy, I was doing the double-nickel. Bottom line: he clocked me at roughly 3000 feet, and he recorded it as 384 feet. Which was a lie. I'm assuming he did so in order to produce a reading that was within the LIDAR unit's operating range.

So that's why if I were you I wouldn't try to fight it based on the officer's representation of the facts. Rather, I chose to go the legalese route and do deferred adjudication. My record was cleared after a year of ticketless travel.

BTW, this was the event that prompted me to upgrade my 5-year old V1 to one with LIDAR detection. It was also the catalyst for me to buy the Lidatek (that I still haven't installed).

Good luck!
-Dave

This is not a "which detector is better" statement but just an observation - my Passport 8500 has never failed to go off when I've been tagged with laser. Whether the detector registers the hit or not is a moot point though, because w/o a jammer you're meat.

Surety Agent,
I would have to agree with the others, either poor aim, unsteady aim, or cop just aimed it everywhere. Laser is promoted as being pin-point; so if aiming at license plate the scatter pattern will not be anywhere near a detector mounted by the rear view mirror. Either this info about the tight scatter pattern is manufacturer bullxxxx, or extremely poor aiming. Cops claim they can pick out one car from many with laser as they cannot do with radar.

If a guy (case currently in NJ) with the Feds) can aim a laser and hit a pilot up in the air, the scatter pattern must be very tight.

BKH,
Agree that detection of laser is too late if driving way above the speed limit. Need a detector/jammer such as lidetak.

Again, I'm just reporting the facts: I've never had my Lidatek go off without my V1 also going off (on laser warning) at the same time. Whether this because the V1 is extremely sensitive and effective in sniffing out the beam or because the beam is being waved over my windshield as it comes to rest (point of aim) on my lisence plate I don't know. I just know that I get a warning from my Lidatek and my V1 at the same time, my Lidatek jams the signal and, if needed, I adjust my speed. Don't others here who run both systems have similar experience?

Derek

PS - And having participated in my share of competitive High Powered Rifles Matches (not to mention a lifetime of shooting rifle, pistol and shotgun) I am familiar with the subject of aim. If a cop, at a 1,000 yards, is hitting a moving target with a pistol type laser gun without the beam moving around quite a bit then he is superhuman.

Derek,
From my experince, the Lidar has a fairly tight signature and I have been hit on 3 ocaasions where the Radar Detector (mounted up by the rear view mirror) stayed silent. Fact is, if the lidar if being fired at close range and aimed low (at the front plate) it is quite possible the radar detector not pickingup any "leakage'. That is the beauty of using lidar gun, and primariy reason why cops use them. :sad3:

cheers,

P.S. Long time no see!! How are you doing??!! :D

Hey Bee:

Doing well. Working hard. We hope to see you and your lovely wife the next time you come through the area. (Just built a new hotel and convention center that is much closer to our house and Delon BMW - will make it easier for you when you come through town.)

For the first time since I installed my Lidatek it did not go off when the visor mounted Escort was blarring. I thought something was amiss until I realized that the officer had already nailed his mark and it was the car in front of me. He had raised his gun and it probably hit my windshield as he did that and it was out of the range of my Lidatek under the bumper. My best guess is that he might have even shot right through the car in front of me in his haste to get on the bike.

If a cop is very careful to keep the beam low and bring it up to the plates it's highly unlikely that a visor mounted detector will alert, particularly at shorter distances than 500 feet.

It's also pretty much SOP for distances to be under 750 feet for the ticket to hold up in court. The reason for that is, according to the letter of the law at least, the officer must first visually identify your vehicle as being a likely speeder before he can actually point a gun at you in the first place. Something to do with that "probable cause" argument. I have yet to see the traffic cop that went by the letter of the law on that point. I wonder why the radar guns dont just print out a tag showing the speed AND the distance, pretty simple with todays technology. I wont wonder too long about that one, I think I know the answer.:nono:

Derek - I admire and respect your experience with firearms. Not many are willing to admit that nowadays.

I have both V1 and Lidatek in all three of my cars. The only time my V1 has "detected laser" and the Lidatek didn't, is when pulling up behind certain GM SUV's with their brake lights on. For some reason, Lidatek is immune to the wavelength of light emitted by those trucks :M5thumbs:
:cheers:

Hey Derek,
Did you say "working hard"?? or do you mean "Hardly working" :7:

Thanks for the info on the new hotel, but we bought a new pad out in Eugene last year so we're just an Hour away from you :M5thumbs: Please give regards to Megan, and we look forward to see ya later this year :)

I'm glad you mentioned this last point. This is a point I forgot to make but you are dead on correct about this ELEVENS - Lidatek does ignore the false signals (and V1 goes nuts) from the high mounted brake lights of GM's SUV's.

(ELEVENS, is it only on their smaller, mid-sized SUV models or have you ever gotten a false signal from a full size GM SUV too?)
