Raleigh PD Laser testing on I440
#23
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.

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.

Nice THread .. Especially for Locals!
They mostly likely weren't testing but actually enforcing....NC SHP does this on the overpass at I40 westbound just past Harrison ave(Old Reedy Creek rd?) they sit behind the sign and get you coming down the hill, also RPD does it at Lumely rd overpass at I540 they will sit up there with blue lights on like they have someone pulled shooting LIDAR...in all cases it depends on where the officer sights in on and when they hit you and your detector goes off it a little late as it is a small cone of detection ( unlike Radar where you can get a signal from running radar) ....generally if you look around at on ramps you will see the take down vehicles waiting for the Radio call....the officer shooting radar/lidar isn't pulling cars over from those locations.
I have the escort 9500ix like it but always keep in presence of mind to be on the lookout visually...the detector works good but seeing a car or someone that looks out of place in the distance has always saved my but...detector saves me when I'm way to relaxed and not looking for traffic enforcement or in heavy traffic.

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. 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!!!

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.
- LIDAR is subject to weather conditions. Fog, Moisture, rain or optical anomalies will prevent a good reading.
- Unlike Radar, LIDAR can LEGALLY be jammed in many states. The systems with Laser diodes work best (like laser interceptor) Some IR LED-based systems have had some effect, but the low intensity decreases it's effective range significantly

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" 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.........

Detectors are like any other tool...if the owner doesn't know how to use it, it is mostly useless. A TECH II in the hands of an untrained person is of no value whatsoever, but in the hands of a trained technician, priceless.

When driving on highways, I always just watch the road ahead of me and look for brake lights or taps on the cars ahead of me. Its instinctual for a driver to touch the brakes when he sees a leo, regardless of their actual speed. Seeing a few taps of the brakes indicates a speed check is necessary, and since highways are always containing traffic around here detectors are not needed.

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...........

AWESOME DIALOGUE MR.LEO. THANKS FOR YOUR KNOWLEDGE AND EXPERIENCE WITH THIS TOPIC!!!

It's NOT a failsafe. It's just another socket in the box.
