PL2 VS PL3 jamming

[IRCMUSA]

No it was there I posted it

See the difference between the detection ranges it has to do with head design. The LPP has a large domed collector inside the head and 1 very directional laser diode so the head can stay small and it doesn’t interfere with itself kind of like feedback when using a microphone.

The blinder on the other hand uses leds they disperse light in many different directions. The sensing diodes on the inside of the head have little metal pieces to cover up the sides to keep this feedback from happening, but in doing so you loose surface area to detect.


The LI has a LARGE dome outside of the head I bet it’s a good performer because it can SEE so well with that large convex lens. It will allow IR light in from many directions.

With active jamming (not brute force) you have to be able to see the signal to transmit a corresponding jamming sequence it cannot make up its own or a PT will occur.
That is why having no feedback and being able to see the signal is detrimental to successfully jamming a gun.


Does it make the Blinder a bad unit no. It jams guns very well! The software is great!!
It merely has a smaller detection radius due to head design.

Shoot the plate below the head JTG every time!

So know in your area if they are taking these close in shots mount them closer to target areas and maybe invest in another head and spread them out a little. Also keep in mind the average Cop will take a center mass shot at all ranges, so you should have enough time to slow down anyway. (if not Blinder has a ticket rebate program).
Lets face it its hard to JTG a lot of today’s vehicles out there because they are so darn
Reflective just know that the 18” rule is only in effect for 1000 feet.

On my vehicle an m-25 installed correctly is just fine for today’s 3rd Gen guns for a JTG
on a small car But a Lincoln Navigator no, you will need 3 maybe 4 heads.

Sophisticated.

Here's the rub: Jammer heads aside:

Both the PL II and the LTI MArksman (20/20) have the largest optics in the LIDAR field.

Both of these guns are corded guns which get 12v into the unit.

Someone is going to have to measure the mW output of the Laser Diode because its NOT a direct Bigger optics is a brighter LIDAR beam.

IMHO its the reverse. a more compact lens "focusing" the beam seems to be best. The Rx lens should have a decent focus of light back to the sensor in order to be really effective.

I suspect this is what LTI has done. Their Rx lens is larger in the Marksman Vs. the UL. When you view the two LTI guns side by side the UL is really HARD to see. It "seems this way to me in the field. Marksman: BAM! Instant.

UL works for a reading. and is dull (visibly)

The lenses will play a part in the equation, but its not a real direct correlation to what will yield the best results........

An example:

Stalker: bright Tx, but weak / smaller Rx lens IMHO.
Laser Atlanta seems to be targeting this with the larger Rx, smaller Tx lens (similar to Pro II).......just ALSO understand both guns came from similar schools of thought because Laser craft (of GA) makes the Pro II and Pro III and LC seems to have fractured from Laser Atlanta years ago.

optics on PLII are much much more soficticated and bigger surface then on pl III...

for my count PL II is a nice LIDAR and PL3 is POS...

The LI has a LARGE dome outside of the head I bet it’s a good performer because it can SEE so well with that large convex lens. It will allow IR light in from many directions.

It's the other way round. The lens REDUCES the field of view but INCREASES the detectability (signal to noise) of the light it actually does receive.

The lens on the M20/25 reduces the vertical field of view (as seen in the beam pattern) but INCREASES the brightnes / detectability of the light in its field of view

as far as i recalled, zr3 has the best laser detection sensitivity outta all jammers. can anybody second on that?? Yet it's receiving component set up is similar to what IRCMUSA just described above for m20/m25. The receiving diode is covered with a metal case to prevent "cross-talk" (to interfere by the jamming diode signal).
so i m suspecting there is something else that made the sensitivity difference.
dont get me wrong, the dome lense inside and outside of LPP/LI definitely made some difference, but is there something else?

Nevertheless, detection is very important for a jammer. it needs to synchronize with the lidar signal inorder to jam. i learned this principle from the mater.

Great video! Thanks.

So you're saying that police should put Veil over their PLIII optics to make it less detectable?

Don’t take what i say for the gospel truth, by looking at the video its all educated assumption

Remember im not bona fide here in this forum that’s GOL's job!!

just offering what i observed from the past, that's all
i m as curious as you are in finding out the explanation. please dont take it the wrong way...

[crazyVOLVOrob]

The reciever in the Escort Zr3 is extremely sensitive, so is the LE30...The only jammers i know of to pick up scatter

I would assume though that the LI has a great reciever as well
