    Default Rear laser protection

    I Currently have a Zr3 jammer with all three heads up front on my Bravada, an will probably by a dual head diode jammer after GOL test reasults are posted. I am wondering if I should put one of the diode jammers in the rear of the vehical, or if I should put the large head from the ZR3 in the back. Or, should I just put all my protection up front?

    ^ Rear protection, from what I understand, is *very* hard to achieve.



    go.mouse had a single-head, previous-version LPP on his late-model (two generations previous) Toyotal Camry, and PTs, depending on situation, occurred between 300 to 500 ft. "from gun." Certainly, if the officer follows the "bait" of the rear-plate, and your jammer is placed there, it would give you higher from-gun PTs, but considering center-mass is so easy to achieve and so many alternative hard-points of aim are present, I would think that sticking to those "worse case" numbers would be valid.

    RacerX's Tundra, though, is protected by dual AL G8s (equivalent to current-generation LPPs) - one near the plate, and one up high, near the rear gate handle cut-out. Combined with three Blinder heads. This level of protection nets him pretty consistent JFGs, from what I understand/have read.

    With your slightly smaller truck, dual rear diodes may be sufficient.

    I currently have a (current generation) LPP head out-rear, right above my license plate. At the same time, I also have my ZR3 head under the plate. The ZR3's positioning is not level - it's actually aimed "up," in my hopes of perhaps better coverage from elevated positions. The LPP head is nearly zero-bubble.

    Even though I drive a standard sedan (with rear aspect comparable to that of go.mouse's Camry), based on his data, I'm still not convinced that I'm getting "unbreakable protection." However, I do think that if I can get at least 500 ft. "From Gun" jamming protection, that I should be able to spot the typical on-ramp or rear-elevated enforcement, and slow-to-reasonable/PSL in the time allotted, particularly if my road-speed is not excessive to begin with.

    Hope this helps!

    all 3 ZR transporders will NOT give you a JTG performance on the back at extreme angle and close range..

    If in your area is used photo jenoptic or photo marksman for targeting from back LED jammer is not an option...

    What about an Antilaser-type of product? The Laser Interceptor perhaps?

    ^ Again, more than likely, two will be needed to insure full protection - it's been shown that depending on enforcement "skill" as well as the exact hardware and situation, it's possible for even a good diode-based jammer to show PTs, on a typical medium-sized sedan w/o "outrageous" hard-points, at anywhere from 300 to 500 ft. "From Gun."

    True JFG in a rear-on scenario will likely require either extremes in terms of passive protection (i.e. VEIL so thick or a set of light covers so dark as to be opaque "by sight," and thus illegal -everywhere- Stateside), PAIRED WITH a single-head diode jammer (on a vehicle of no greater rear aspect than a typical sedan) - or outright dual diodes.

    There's plenty of videos out there to support this, yes, some are even from those selling the very same diode-based jammers.

    Of course, in the real-world, it could very well be that an enforcer may not have situations biased in his/her favor, and a single-head rear diode could provide you enough protection. But again, this is playing the odds, and the odds here are significantly worse than that of the "single-head up-front" scenario, for frontal protection.

    I don't think that the OP was thinking about using all three of his ZR3 heads on the rear of his vehicle.

    He states:

    I am wondering if I should put one of the diode jammers in the rear of the vehical, or if I should put the large head from the ZR3 in the back. Or, should I just put all my protection up front?
    This would break down to the following three scenarioes, in-order of his sentence/question wording:

    (1) one diode front, one diode back
    (2) both diodes front, rear ZR3 head back
    (3) both diodes front, all three ZR3 heads front, NO REAR

    He states, also, that his current setup is all three heads (ZR3), front.



    I don't think that he is thinking, at all, that even three ZR3 heads will be anywhere near sufficient to protect his rear-profile, which, as an SUV that's rather "boxy" at that area, is decidedly hard to protect.

    Hmmm...here's what I would think:

    Leave one diode head up front, center mass, and 2 of the "front" ZR3 heads up front, near the head lights.

    Then, place the other diode head above the license plate, and the rear ZR3 head near the passenger side tail light, assuming that the LEO will first go for the license plate, then go for the nearest tail light(assuming they shoot from on ramps.)


    Or, just place both diodes up front, and the whole ZR3 system("rear" head over plate, other two heads near tail lights) in the back, assuming front enforcement is more prevalent.

    ^ That's a good thought - biasing more protection towards front enforcement, should that be more prevalent.

    My only worry in that case is for the off-chance rear-enforcement encounter. The ZR3, which is barely effective for protecting even a much smaller vehicle - depending on the enforcement hardware - may be totally ineffective employed thus.

    I'd rather then just keep the entire ZR3 setup up-front, too, so that it would have best-odds against those few hardware for which it is still quite capable.

    ZR3 has saved me from the back....
    ( It was prob a pro laser III, but it would have been a ticket w/o the jammer just the same.)

    ^ Exactly - it's probably very much hardware-dependent:
