PL2 VS PL3 jamming

This is why the pl3 is easier to jam the heads can see it better!!!

Of all you videos this is by far my favorite because it changes the way we all think about the PL2 now I believe. I would agree with your theory that it's less powerful, thus you have less light scatter.

You know what would be very very cool? Put a Blinder M45(single head) at the exact same spot you have that LPP. Stay at the same distance away, and lets compare the reception of the LPP vs an M45(single head.)

Now that would be a bad arse test and something nobody has done before. Thank you very much for the cool video.

Awesome Video.

If this was filmed in the day time its sensitivity would be reduced even more.

I think you are correct again here and its not that the PL3 is easier to jam its that the jammer sees it much better.

I wish we had more sensors to mount at different parts of the car so it could pick up the beam better.

Then we could get JTG's all the time off a single head.

I bet the beam of the laser atlanta is also quite dim.

I think the optics would have to have been better on the PL2 vs PL3 for the very fact that the beam is so dim.

I love IR video. I need to get me a nightshot camera with a 850nm filter too

I still think optics have something to do with it. You'd think that it's have to have good optics to be able to pick up a weaker return beam.

Also, I found it weird how as the test progressed, the PLII seemed to became harder to detect. At first, the LPP detected it when the beam was under the driver headlight. In one of the later tests, you were actually able to shoot further in (closer to the head) without the LPP picking it up.

Good stuff

Muahahaha! :twisted:

I wonder what collectors/sensors/receivers could be made out of and how.

I donno.....if they were small clear LED's like in some radar detectors that would work....the problem would be that we'd have to make a lot of holes in the car to mount them all over.

Clearly this is why a dual head LPP is better...you can spread out the heads wide for better coverage.

Its clearly not the light issue....Its the sensitivity and software that sets one jammer apart from the rest.

Perhaps a better lense filter maybe? Maybe its filtering too much light to cut down on falses which is reducing its sensitivity a bit?

I have a question IRCMUSA can you play with the LPP sensitivity settings...the ones you set for range that make it pick up further in parking sensor mode

Try and set on the most sensitive for furthest range to see if it picks up the laser better than it does when its set on the least sensitive range.

That has been running through m y head for awhile now and it would interesting to see if its true or not

Please please please...
Do a similar comparision between a m25, m20, and lpp head.

To keep things fair, test the distance to sensor side of m20/25

**IRCMUSA** · 10-04-2007, 08:34 AM

i will see what i can do guys
m25 single got it.
play with the parkingsensor sensitivity got it.

cant do the m20 its new in the box id like to sell it i need some money.

Laser pickup performance is definitely unrelated to parking sensor range.

The microcontroller inside the head can and does change the sensitivity of the receiver on the fly (for example, to compensate for ambient light). Therefore, it doesn't need to use a lower sensitivity all the time if parking distance is set to minimum.

Now disabling the parking sensor would possibly make a negligible difference (maybe jamming a pulse or 2) in the unlikely case that the laser gun starts at the same time as the parking sensor laser pulse.
