I can tell you with an experienced officer that none of the detectors are going to work in time for you to react. The newer systems do not emit any signal, and after several years on the job, a cop can guestimate your speed within a couple miles per hour an then activate the radar/laser. It takes about 3/4 of a second to react to the detector and at 70 mph you've gone 100 feet or so before you brake and the radar/laser is intstant. I've seen many deflectors, jammers, and systems with guarantees that did not hold up to the expectations...

If i am correct your laser detector works like the radar portion.You don't have to have it on your car.It picks up the signal hitting cars ahead to give you a warning. I agree with the person earlier.Most lazer guns i have seen have a sight like a scope,he sees you befor you see him.Your only hope is to get notice from cars ahead. If it hust went off when it hit your car it would be to late.

The headlights provide the other best surface to get a reading, but Unlikly on a c6.

This being said, There's also a Minimum and maximum range (again pending laws in your area) at which Laser speed tracking is deemed admissible my a court. Even from an elevated position like a bridge, a laser would be able to pickup scatter and at the approved range of detection, the speed displayed will actually be slightly (fractions of an MPH) slower than your actual speed due to the angle.

Also keep in mind that a typical LEO traffic unit is running laser from the side of the road and not always aiming at the outermost lane.

Your best bet for positioning the Jammer/Shifter pods is still going to be in the radiator opening as wide and high as possible.

Good to know on this point! There were cars in-front of me, so that could explain the pause in the alert - perhaps targeting one car then another. If so, the detector provided good warning time.

No front plate required in NC, so I am curious if placing shifters in the grill area would be too low if the laser is focused on the windshield. In this scenario it is a three lane highway. The LEO was positioned directly over the far left lane. I was approaching in the far right lane.
Also, what is "scatter"?

So no radar detector can see laser beyond a laser that touches the detector's sensor?

I prefer the Valentine One for the reason that it tells you where the signal is coming from. For me this is critical. I had heard that Valentine's patent on the arrows expired and that we should start seeing them on other detectors. I haven't seen any yet. I also haven't shopped detectors in a couple years.

When it comes to radar, it's very difficult to get a reading on a Corvette due to it's shape. The lower and more aerodynamic a car is the more difficult it is to get a reading. Much like a stealth fighter/bomber. The Corvette as similar angled surfaces that reflect the signal in random directions. This is especially true when there are other vehicles around. If you're next to a semi then it's impossible for the radar to read your car as it can only 'see' the semi due to it's large size and flat, vertical surfaces.

Laser/lidor is similar but is so much more accurate and refined, it's beam is very narrow, and with it's aiming capabilities.

Think of radar as a musket from the American Revolution and laser as a M4 w/ a ACOG scope.

True.

However, LIDAR has a few disadvantages to LEOs:

- LIDAR MUST be aimed by the individual. This requires effort....aka no more sitting on the side of the road with your vehicle-mounted radar going while you goof off on youtube.

well, its more like the corvette forum I goof off on, but I assure you, LIDAR is far more simple to use than radar. Radar requires much more observation to traffic to determine which vehicle the radar is displaying. LIDAR is the opposite, point and shoot, 99% of the CF members could go out with 5 minutes of instruction and using LIDAR AND be 99% accurate, radar not the case.



actually, it effects the range, not a good reading.



if you are going to shell out the big bucks on a jammer, kudos; as soon as you pass me, there is another idiot (not calling you an idiot) doing the same thing or twice over...........

Using LIDAR where I work is like fishing for 8ft fish in a 2ft pond, its a joke. And im not talking 5,10,15 or 20 over, im looking for 40 over and it usually takes about 3 minutes to get one.


And just food for thought, and this is for the OP, the reason your detector acted goofy was probably him trying to get a reading and couldn't. His elevated position is not how you are suppose to use the LIDAR, you are suppose to be as parallel and level to the target you are trying to obtain. But as I argued in several other threads, we have to do things that keep us safe, like and overpass. So the beam was being reflected off your car for several seconds before the second LIDAR eye was able to receive beam that was transmitted due to the angle at which the operator was shooting. Again, as someone else stated, it only gives us a speed LESS than actual, so its in your favor.

As I teach, the optimal spot for shooting is the front bumper. The beam width is "about" a 3ft by 3ft box, as I explain to the newbs. So, if the beam is not specifically targeted at your car, I cant see how a radar detector would go off and benefit you to the "trap:rofl:" ahead. If your radar detector goes off, and the operator is using it correctly, im sorry, I think its too late. Human reaction time alone, to hear the alert on the detector, the tendency to look at the detector and the brain processing it and telling you to slow down, I should have a locked in reading bye then.........

No, laser scatter can be picked up. It is usually 18" or more from where the laser was pointed. Also, there is shear physics, that if they point it at a headlight on say a Vette, 18" above that is going to clear the fender and could be picked up by others detectors.

I run the 8500ci with the shifters, and have excellent success against LIDAR.

Also, your previous statements were a little odd, you said that the officer was on the overpass, but that there was no car: so did you actually see a cop, or is it possible you just got a false positive from your detector? This can happen occasionally from certain taillights etc.

Thanks for the heads-up on LEO traps in the RDU area. Any more locals have data on where these LEO are would be helpful. Not that I intend to go over 65 but our cars get to 65 very easily...its the car's fault bc its too fast.:yesnod: JK . I stay within 10 mph most of the time. I have a Beltronics V8 works fine but won't beat the Lasers I bet...especially with newer and newer tech. coming out each couple of years.

Nice work Corvette Forum posters!!!

Inner beltline/440 1000 ft prior to the lake boon trail exit. Just as you cross under the Ready Creek pedestrian overpass around the bend where it goes 2 lanes to 3 lanes. RPD parks a white SUV (tahoe?) in the far left emergency lane to take readings and the chase crew is up ahead... Seen this spot a few times. 440, in general, is not a highway you want to speed on.

I will give you guys some insight. I am a motor officer in California and in order for us (officers trained with radar/LIDAR) to use RADAR or LIDAR we are trained in visual speed estimation. In California the courts established that we can be within +/- 5 mphs in our visual speed estimation. I use LIDAR for speed enforcement. I use a custom signal pro 3 laser for enforcement. We first do a visual speed estimation then I activate my hand held laser to verify my visual speed calculation. I can issue a cite strictly on visual speed estimation.

One of the posters stated that LIDAR can not be used when pointed through a closed window or windshield and that is incorrect. I have used my LIDAR when driving a patrol car when my duty bike was getting service done and it works perfectly. LIDAR is target specific unlike RADAR that sends out a cone and the officer has to determine which vehicle is the fastest in the group.

Being a accident investigator as well the fastest perception and reaction by scientific study is 1 second (.5 second to perceive and .5 to react). What this breaks down to is that when your laser detector activates the officer using the LIDAR has already captured your speed before you can react. Many times I have already locked in a speed on my LIDAR and then I watch the vehicle brake aggressively.

Happy motoring.

Driving to 1 on 540 from Brier Creek just about to pass Falls of Neuse and I saw a popo standing on the upramp point what I believe was a laser with about six cop cars down the ramp. They were obviously tagging and bagging. My question is, is Raleigh now using laser technology that my 9500ix will not pick up because I was in front of everyone in the very left lane with a Torch Red GS. You can't tell me they would not of pointed that laser at me? The 9500ix remained silent...I was only doing 75 in a 70...

This could give me a reason to upgrade to the Max...

My guess is (and I would appreciated being corrected) that laser readings require some skill to get focused on a reflective surface, on a Corvette, that actually gives a reading? And if so, a driver has some moments in that time to adjust speed?
