Has anyone heard anything about Escort's ZR-3 Laser Shifter/Jammer. Does it work as well as the Lidatek?

See website:

The ZR-3 is simply a stand alone version of the laster shifter that is included with the SRX and SR-1 integrated radar detectors. Do a search on SRX or SR-1, or just go back a couple days, as there was a post with some pictures of an SRX installation including where the shifters go.

The Lidatek uses LED lasers to confuse the Lidar unit, while the Passport "shifts" it. Several tests have indicated the Passport unit works just fine, as does the SRX an SR-1. We have had people post regarding them working.

The primary advantage of the Lidatek IMO is that it is on a 5 second timer, and that the manner in which it functions is (for now) not detectable by any law enforcement products.

The advantage of the Passport systems is their integration into the car, the ability to use 2 front and one rear shifter with a single electronic module and their availability as a complete laser/radar package.

A lot of folks point out the rather high retail installed price of an SRX and SR-1 (negotiable, depending on installer), but as far as I can see, a V1 w/ remote, Lidatek LE20 with 2 modules will price out in the same range once installed, particularly if you add rear protection to the Lidatek, which would be mandatory in my area (one frequent rear targeted trap, and seen several others).

I have both. SR-1 in M Roadster, SRX in M3.

The SR-1 is based on the Escort 7500. It does NOT have any active capabilities and is NOT VG-2 proof.

The SRX is based on the 8500 and is VG-2 proof and has laser shifintg (the term is only that Escort doesn't want to advertise jamming, works the same way).

I saw the SR-1 components over that the installers, and there was an active laser shifter module for both front and rear.

In addition, they website has the following copy directly over a picture of a laser module
"Passport SR1's laser section incorporates special low-noise circuitry and 8 high-performance laser sensors (4 front and 4 rear)."

I'm certainly not questioning that yours has active laser defeating, as I'm sure you would know if it does. Any thoughts?

Read your link carefully. There is no mention of laser shifting, just laser detection - front and rear. IMO, worthless as far as laser protection goes.
