    the fact that V1 alerts before LI may be because of heightened V1 position. also it can happen that some of LIDAR light goes through the glass of car in front of you, and V1 picks it up...

    I know that my V1 picks up laser scatter a lot, that is usually my hint to slow down before my LI even goes off.

    but back to topic

    LI jams IMMEDIATELY upon detection but there is a 1 second delay before Ms. LI makes her announcement!

    Strange.

    Why is he not getting true-JTG up-front?

    The rear, I can understand - the plate's down low, way low, and his rear deck's vertical plane is very large, as well as is white.

    That, combined with his farther-displaced set of tail-lights, would effect closer-range PTs - and moreso if a glancing/lucky shot from the LIDAR was able to capture his rear spoiler surface, which is *very* far from the protection of his rear heads.....

    But his frontal profile is essentially the same as hockey's, and the physical size of his vehicle isn't any larger, either. It's also white versus metallic silver, again, what I'd consider to be even-draw.

    What's the issue, here?

    Just that the front mounting need to be refined?

    And also, what can we do about the rear?

    ^ I ask the latter not so much altruistically , but with a hidden purpose, too, as I'm considering an Evo X as my next car.....and that vehicle has a rear plate/profile setup very much akin to muledoe's.

    The front seems fine to me really i might just need to make sure they are level again. As far as them being spread out evenly and covering the car at center mass i think its fine.

    Now for the read i cant think of anything. Maybe just little messing around with it, but other then that i cant move them anymore out or up or anything, i am stick with the rear set up. That is why i asked has anyone actually tried a putting a head behind the glass and it working? If it does i wont mind added a few more heads and sticking them inside, no problem 8 head set up would be crazy tho haha

    I think that a "through the rear window" kind of thing can work - but here's the problem.

    We've seen countless corroboration of data from our fellow hobbyists and enthusiasts to say that police LIDAR devices, when shot from within the vehicle, through vehicle greenhouse glass, takes much longer to acquire lock. This translates, in-part, to a much-decreased lock-distance from-target.

    Similarly, we've also had confirmation from ELVATO and edwierd that the ZR3, an LED-based jammer, becomes all but ineffective when stationed behind vehicle greenhouse glass.

    At the same time, Mike Valentine is quoted as having said that putting the V1 behind *any* type of vehicle glass is akin to putting on sunglasses - that it will, to some degree or another, reduce the LIDAR sensitivity of the unit.

    My guess, then, based on these observations/comments, is that the police laser device is able to literally "out power" ( I know, this is *really* inexact language, and very qualitative, but without true knowledge of what's actually going on, it's the best make-do description that I can come-up with ) the limitations that passing through vehicle greenhouse glass imposes on it....something which is nearly impossible for LED jammers to accomplish, and which is likely also going to severely degrade the output of even the coherent-light-source that's the laser-diode equipped jammers, such as the LI.

    But your situation is unique.

    Your rear heads do provide coverage - but just not "true-JFG."

    If I'm not misunderstanding you, muledoe, what you've said before is that at close range, at the rear, you suffer PTs, right?

    So, indeed, what if you had another two, or even three, LI heads buried back there, near the rear windscreen glass?

    The question becomes whether or not they'd be "powerful enough" to cover your needs at such CLOSE ranges - would they be able to overcome the fact that they're situated behind the rear glass?

    I dunno.....
