Thumbs up Blinder M25 & Escort ZR4 on Lexus IS350

This is a customer that wanted to test his Blinder M25 and Escort ZR4's out. We tested this customers car with the Pro Laser III. Both the Blinder M25 and Escort Performed very well. We were able to cut each one of the jammers off to test the other. The escort ZR4 has good front protection, However the rearZR4 head is not enough coverage for the back of this car.

Question:

Time-point 0:29 through 0:32 - Cameraman/narrator indicated that the ZR4 rear head in the middle, above the plate, was flanked by two Blinder heads. Was the rear Blinder setup tested? If so, results?

Comment:

Please have the customer re-test his setup:

(1) At night, frontal aspect, with both Blinders and ZR4s on.

(2) At night, rear aspect, with both Blinders and ZR4s on.

Try to get as many different LIDARs as possible.....

My fear is that with both the ZR4 as well as the Blinder heads being unconventional in design (with IR-transparent portions not limited to just their frontal "lens"), that cross-talk from light-scatter (emitted light from the jamming pulses) may be a concern, particularly in darker surroundings.

The wide separation of the forward heads may mitigate or even outright eliminate this effect, but it is not a possibility that should be disregarded, given the catastrophic but unfortunately totally unpredictably unpredictable nature of such crosstalk events.

The rear setup would be a great concern to me, if I were the vehicle owner, as the proximity of the heads, along with the way such scatter can be so easily reflected by the nearby body-panels (proven now in more than a handful of installations, where multiple jammers are active, simultaneously).

The problem is unfortunately only exacerbated by the fact that both the ZR4 as well as the J16 variant of the Blinder are such excellent receivers, as demonstrated by their abilities to counteract the TruSpeed.

Talking Re-test

TSi+WRX,

Yes the Escort head, is in the middle with two blinder heads on each side. Even as close as they are, the escort heads do not effect the Blinder heads and Vice versa.

We tested the Blinder but it was in its 30 second test mode, which means it was not ready to jam until after 30 seconds. The customer didn't have alot of time and was on a tight schedule. We did not get to test the Blinder rears On camera, However we got one test run with just the blinder heads on, and got one punch-through at 535 feet. After that it was JTG on the tail lights and center.

I will try to have this customer come back out so we can test your theory of night shooting with both on. The Blinder and escort work real well together. Thanks for the feed back TSi+WRX. I wish you could come out to atlanta to test with us. It would be good to have another hobbyist who enjoys what we do.

I'm glad that this was looked-into.

The prospect of cross-talk has always concerned me, particularly with the models which are above-average receivers, compounded with their unique head designs.

I think the rear performance is very indicative of what we can expect, on-road, with these jammers.

In that the most crucial moments will be DIRECTLY after the vehicle passes the enforcer, I think that a "plate centric" setup can buy at least some time to react, but that at both mid-distance (approx. 450 to 650 ft.) as well as at longer distances (approx. 1000 to 1300 ft.) exists "critical points" where some setups/systems will suffer potential PTs.

With the rear of the vehicle being so hard to protect, I think all that can be asked for is that, while seeking "true-JFG," more priority be paid to the setup being able to jam "anywhere" rear attempts for at least the first 500 ft. or so (thus allowing the driver/vehicle to correct-to-reasonable/PSL), in reasoning that the driver should have made visual identification of the enforcer/enforcement threat as late as even "being on top of it," but having taken corrective measures instantly thereafter.

I hope you guys won't see any crosstalk issues, but it's definitely one to look out for, given the fact that both systems emit light in a non-traditional manner, and also in that both are such excellent receivers.

If crosstalk does present to be an issue, I would then recommend that this particular end-user simply switch their ZR4 to "Receive Only" mode, as the overall performance of the Blinder J16 revision much exceeds that of the ZR4.

Be sure that the vehicle owner realizes that this testing may take some time to complete - in at least two of the reports of such crosstalk, the effect was not observed in a consistent basis (i.e. the "combo system" sometimes showed JTG behavior, but sometimes, PTs were elicited at short, medium, or long distances, without any pattern or predictability), so repeated runs will be necessary.

I think it would be fun, too!

Default Rear Protection

TSi+WRX,

I agree if doing a center setup properly with two heads buys you some time before the officer can get you, then I think its worth having something in the back versus nothing. The back of a car is so hard to protect with any jammer.

The Pro Laser III at far distances is capable of getting punch-throughs on my car at the 800 foot plus mark. If I switch to the Ultralyte I can't even get my car after 250 feet down the center. The beam divergence I guess plays a big part.

Technically if you have two blinder heads spread out 12 inches apart on the rear, its suppose to jam better the further out you go. What I have found is the back of cars have so much to cover, that the heads cannot always reach every inch on the back. I tested the Truspeed against my rears. If you go down the center it will jam up to 1000 feet. The minute you move the Truspeed over to my tail lights, its instant punch-through. The Blinders can't even see the beam because its so tight and such a low powered gun.

I believe that putting 4 heads on the rear of a car with any jammer whether its Diode or LED, should give you JFG performance. This is only if the setup is spaced out perfectly so that every inch of the rear is accounted for.

All we can do is hope company's like Blinder, and escort, etc come out with a head that is so powerful and can truely defend the rear spacing on the back of cars/trucks. Maybe a skinny Magnet with 25 built-in LED's can be put accross the back of the car to cover all surface areas. LOL!! The technology is there to do such things.
