I know laser is instant on but the jammer disables the reflection
by throwing up a "cloud" of IR that kills the Doppler effect so the gun does not register a speed.
The jammer works at the speed of light too.
BTW if you happen to be slowing down quickly while being painted by laser even without a jammer (which is legal) the gun will go blank and not register a speed because Doppler needs a constant speed to work.
I've had LEOs lower the gun and raise and shoot it again after I have slowed down and turned it off

Also I know radar can be instant on but I said in my area the LEOs sit around corners and over hills or behind bridges with the radar on all the time.
In 15 years I have never been painted with instant on radar because almost every police car has rolling radar and human nature being what it is it seems to be too much unnecessary effort for the LEOs to do the instant on thing since they make their quotas without it .

 

I'm very familiar with how each system works, but I was making no reference to laser defense (transponders) at all. Just pointing out that ALL laser is stationary and instant-on.

Since you mention it, I too have laser jamming capability, and it has proven very for me effective when used as directed.

 

Yes and in my experience some cruisers have the laser built in out the front or back so the LEO does not have to open a door or side window and use a hand held gun.

My mechanic services trooper cars so I have seen these devices close up.

 

From your description, it sounds as though you're saying the "laser" gun is mounted on a fixture/bracket so as to shoot THROUGH the glass, i.e. windshield and/or rear window. Correct? Or, are you saying this "laser" is attached to the car outside the passenger compartment, i.e. to the front buddy-bumper and also the rear bumper?

 

On the tops of the fenders front or back but I suppose bumpers would be ok as well.
The car has to be at a certain close range before the LEO paints it with a fixed mount.
Laser has I believe a small reflection circle about 5-6 ft wide like a spinning rope at 1400 ft and probably gets smaller as you get closer.
My jammer went off pretty close to a cruiser at a sign gantry about a month ago without the LEO using a hand held gun, a painting a lot closer than typical.
I didn't get a chance to turn my jammer off until I was right at him.
He pulled out but didn't pull me over.
Maybe he was done at this spot as I had never seen a cruiser there in 15 years and I drive this route every day.
I was a bit unnerved and quickly took the next exit anyways.
Luckily I always slow down for this gantry anyways as it has a built in radar
to monitor average traffic speed so I don't want someone falling out of their chair somewhere.
A hand held gun is more versatile with a range of 1400 ft or so and probably cheaper than a hard mounted unit.

 

the V1 has a remote option that allows you to hide it.https://store.valentine1.com/Store/closeup_20110.asp

from their website:
I want a hidden detector, with the receiver remote-mounted down in the grille, but you don't make one. Why not?

I want a remote too, but I don't want to give up any protection. For the same reason you see high radio towers, the radar detector antenna needs to be high in the car; it sees over hills better, increasing range.
Mounting down in the grille amounts to a low tower. You also have the problem of traffic ahead blocking the signal. The only time I've seen a grille mount outperform a windshield mount was a case where the detector could look under the truck just ahead. Normally, a high mount has an advantage because it's up where it can see through the windows of other traffic.

Another thing; the really sophisticated direction finding and bogey counting that V1 has requires perfectly synchronized information from the front and rear antenna. It's possible to maintain that synchronization when the system in broken apart into units at the front and rear of the car, but you pay F-15 prices. My best compromise between maintaining performance on the one hand, and hiding the detector on the other, is the Concealed Display. This keeps V1 in the window where it works great, but operates "dark;" all the light-up warnings are transferred to a small Display that you can locate where only you will see it.



Your Concealed Display looks like exactly what I've been looking for, a way to keep my detector warnings all to myself. How hard is it to wire up?

How, exactly, is the "laser" beam directed at specific vehicles? We know there's no such thing as "moving" laser, so how is the LEO "pointing" at specific vehicles while he is stationary? Moving/adjusting his car slighthly so as to "aim" the laser?

Remember, laser beams are approximately 3' wide at 1000' (typical LEO shooting range to begin "tracking" is 1000'), but tracking a moving vehicle (target) still requires the ability to adjust/alter the beam so as to hit the intended target.

 

As I said with a fixed mount the LEO has to fire it when a car is in a certain closer range since beyond setting the angle initially he can't move it around like a hand held gun.
I'd say this was at a range of 4-500 ft.
As I said above I always slow down for this gantry anyways as it has a built in radar/ laser of some sort to monitor average traffic speed in the morning (both V1 and LI go off) so I was doing less than 10 over since I don't want someone falling out of their chair somewhere.
The LI has a sexy talking chick that identifies what kind of gun is being used and can be updated through a com port.
This time instead of saying unknown gun it named one and then I saw the cruiser.
This laser would not be practical at a busy time on a highway.
This is my just opinion anyways as it all happened so fast I had very little time to react let alone make studied observations.
This was a perfect place for it at 11:30 am when it's not busy and no hand held gun shooting was done but the jammer went off.
I keep a better eye on this gantry now and it's not really a good overall spot on a straight piece of road and I kinda doubt I will see a cruiser there again now that I have thought about it and realized how limited this type of laser is.
My mechanic said they have fixed laser but it's expensive and not common or as versatile and this has only happened to me once (so far) in 15 years of driving this road.
LI jams to gun pretty well all known lasers but I was still unnerved since I didn't turn it off until I was at the cruiser even though I wasn't going fast enough to get pulled over.

 

Are you saying the ticket you received was laser (LIDAR) or radar?

IOW, you did not get any tickets from some LEO driving/operating one of the so-called cars with "fixed laser" mounts, correct?

As far as I know, there are NO "fixed laser" mounts on LEO vehicles, and I wonder if your mechanic wasn't seeing one of the newer Automated License Plate Recognition (ALPR) systems that are just now starting to come into service at some locations around the country, typically in larger metropolitan areas. Those "laser" units you describe may very well be ALPR cameras (which is what they are) that use infrared and OCR software to rapidly "read" license plates. LEO vehicles with ALPR systems WILL have one (or more) cameras externally mounted and aimed to as to give the best effective angles/viewing position necessary to "see" license plates.

If you can, snap a picture of this LEO vehicle next time it shows up in this shop you speak of.

 

Perhaps you are right.
My mechanic is not an expert on this and his info would be second hand.
I didn't get a ticket as I said but the whole experience was unnerving as
I was laser painted at close range and this type of thing had never happened before.
I'll keep it in mind to snap a pic next time he has a cruiser in the shop
that has fender mounted devices.

 

I think the LEOs are cheating too by using radar and lasers, especially instant on

Lets go back to the old days when they have to pace you

 

In Car & Driver's latest issue, the new Escort Passport MAX beat the Valentine 1, primarily because the MAX had superior features and higher intelligence.


Now, the Escort MAX is more expensive, but according to the comparison article, its performance and features are unparalleled.
