Default Laser "Shifter"

Has anyone had a laser "shifter" such as the Escort ZR4 installed in their S4? If so, how were the laser head units installed in the car, and importantly, does it work as advertised?

Thanks

Default It's a jammer

Receives signal from police laser gun and transmits jamming signal. Police cannot get return lock. It is legal except Virginia. Requires two sensor/transmitters mounted in front, likely in grill. Wondering if an S4 installation requires cutting or something drastic. Look at Escort ZR4 or Blinder.

It "jams" police radar significantly reducing the distance from which their laser guns can read speed.

The escort jammer is known to be pretty weak. From what I've read; laser interceptor is the best and the Blinder M27/M47 is close behind.

Read up on it for yourself at the radardetector.net forums.

Worth reading the reviews on the "laser interceptor" I wonder if other units have the same issues;

http://www.laserjammertests.com/lase...ptorreview.htm

Seems that at $500-$1000 for one of these things you would really be better off paying for a traffic attorney if you got a speeding ticket.

Or, better yet, use some brains about when and where to speed. I have little sympathy for all the whack jobs in my neighborhood who think it's okay to drive 40 mph through a 15mph elementary school zone.

I could have sworn that jammers are illegal in most states (hence the hiding them in the grill), where as Lasar/Radar Detectors are legal in most states. Comments?

"Laser Jammers and Radar Jammers are illegal in the states of Nebraska, Minnesota, Utah, California, Oklahoma, Virginia, Colorado, Illinois and Washington DC."

http://www.radarbusters.com/legalissuesarticle.cfm

I can't vouch for the site itself, but it looks legit and was the top google hit when I searched for it.

I also remember reading in the forums that laser jammers are illegal in California.

I'm in Canada. I haven't taken delivery of my S4 yet but I installed a ZR4 in my A4 about 5 years ago. I buried the two front units in the fog light grills but I needed to cut the plastic ribs. The plastic A4 fog light grills didn't cost much to replace if you screw it up. I also mounted the unit meant to go on the back trunk in the center grill but it sticks out a bit.

Does it work? The thing rings when its supposed to but I haven't had an occasion to find out that it doesn't scramble the signal. I do know that I haven't been pulled over the 10 - 15 times that I was doing 12 - 15 MPH over the speed limit. I'm a lead foot on the highway but haven't been nailed by laser going at speed that would catch a ticket for sure.

I've used both the Blinder Extreme M20 + Laser Interceptor. Both had two forward facing receivers/emitters. Both were installed on previous cars (STi's) - I haven't yet ordered a jammer for the S4, but plan on doing so soon.

I've had very positive results with the Blinder. On more than one occasion it has alerted me to (and presumably jammed) laser. When it activates, I typically check my speed, quickly adjust if necessary, then switch off the jammer. I've noticed many confused faces when I then pass the guy shooting me.

I had the Interceptor on my most recent STi, but sold it before it proved its value. So I can't comment on the effectiveness of that unit. I bought it due to the high marks from http://guysoflidar.com/ - so I presume it's quite effective.

If I do install a jammer on the S4, I'll make sure to post a DIY with lots of pictures. =)

Here's a link where someone installed one of these on a S5.

I'd be up for this for sure; I'm basically in San Jose and I think the rest of us are in the bay area as well.

Default Thanks for that

Very helpful. I was wondering if the spaces in the Audi grill were big enough to accept the sensors without cutting.
