question about my zr4.

[Arashi666]

well it seems that way just because your head doesnt work that fast, not fast enough to see the difference at those speeds, and im talking the speed of light, and thats damned fast

[Retaliation]

I think its not that the heads won't go off at the same time. Its that the rear ZR4 head is not in sync with 2 front heads. Therefore, it may actually interfere with the front heads when they are jamming. As far as I know, nobody has tested this yet.

No the heads do fire at the same time. I played it back thru my camcorder on my phone. and all 3 heads fire exactly at the same time. if there not sync'd then they got me fooled. because there firing together.

[Retaliation]

I mean the jamming pulses are not synced to work with each other. The rear head either has different algorythms than the front heads or the 3 heads are just not synchronized to work together. I believe this was stated by Roy when the ZR4s were first released.

[Arashi666]

I get what youre saying and all, but it may look like theyre all firing together, but at 100-some-odd pulses per second, your brain cant register a small difference if even one pulse is off

and yeah I agree with retaliation, and I just explained why, its all starting to fire, but it doesnt pulse at the EXACT SAME rate, and that can cause confusion

[06blackgto]

I see what you guys and roy is saying. however for some strange reason I believe that it will help. it helped the zr3's. when it was ran like that. I just wished I knew someone w/ a lasegun around kc to test it out. hopefully someone will be able to test it out on here sometime.

^ The thing is, with the ZR3, it was never said that using the rear head in a frontal application, in conjunction with the other heads, would be a potential cause of performance degradation.

With the ZR4, we've got this warning from the likes of Roy himself, who has in-roads with Escort's inner sanctum.

The truth of the matter is that what we can "see" simply doesn't prove much - can you say that you can tell the difference, visually, between 20 pulses per second, and 21? or even 30? We could even somehow time the pulses, and it still won't prove anything...for what if the problem isn't caused by pulserate, precisely - but rather, is concerned with say, the peak output of one not matching the other? Too many potential confounding factors.

At the same time, to take the logical step and to examine the issue from the other side of the equation, we've seen from past history that "Escort's word" about something technical like this is less than totally trustworthy, too.

What needs to be done are some controlled runs against a number of different LIDAR guns. That's the only way to be sure.

totally agree....


I guess I'll be the guinea pig for now... just to have to find a buddy who's buddies w/ a leo w/a lasergun....

Atlanta Jammerfest hopefully will reconvene fairly soon for some more testing. One of the things which I will be testing is my ZR4 with all three heads up front. One test will just be with all three heads up front, but another test will be with a small metal or plastic shield installed on the bottom side of the rear head since the rear head emits a much taller vertical cone. My theory, to be put to the test, is that if I block the rear head emissions from striking the ground close to in front of the car, then hopefully there will be no feedback issues due to scatter back into the pair of front heads.

^ All good stuff!
