Radar Detector/Laser Jammer Setups

Just curious, what do you plan to modify? They are just detectors, the jammers never seem to work effectively other than to let the police see you sooner.

It's not hard to jam radar with a microwave transmitter, it's just illegal as all heck. Passive jammers are a long running scam.
Jamming laser? Nah... don't buy the hype- you're MEAT if they have a laser. The headlights are easy targets for the laser gun and have a nice huge return.

Any way you slice it, using a radar jammer or laser jammer could get you a nice ticket for obstructing justice....or interfering with a police officer in the line of duty... Look it up...
Kobyman - go to www.radarbusters.com and read their tests.. They are pretty good and fair tests. You'll see that the jammers really don't work to well. Even the best detectors don't work well against the POP guns unless you are in a really busy area with lots of traffic being checked. Open road your going to get hit.

Why is this in the Discovery section? Why do you need a radar detector/jammer? It's obviously not for a Land Rover

Actually it is for my DII. Highway and open roads, it's easy to drive over the limit regardless of what kind of vehicles you're in

That whole thing about receiving a signal, manipulate and resend is bull.
The radar gun gets a HUGE return from a vehicle, especially a truck. The largest return comes from the frame at the top of the windshield, according to the training manual that came with the Stalker Radar I used to use. You can't absorb *all* the radar energy and make it disappear, then send back a manipulated signal. The only way a real jammer works is by overpowering the receiver in the radar gun with junk signal.
To transmit on that freq requires a permit as well.
Laser- it's pointless to try to confuse it. IR LEDS on a license plate frame do nothing- most times when I used one I'd go for headlights- they give a HUGE return, just as good as a reflective license plate.
If you did buy a real jammer- and they cost a LOT, you'd get SO busted...

Steve,
They just showed an episode of "Fifth Gear" on Speed Channel where they tested a laser jammer and the results were quite positive. Simply, they work. They also detect the laser directed at the cars in front of you, not just the one pointed at you.
Briefly, they mounted the unit in the front of a Volvo wagon, just above the license plate, and below the bumper. The unit detected the laser, jammed the signal so that the gun showed an error, warned the driver, and then shut off.
The theory is that the cop gets the error on his first try and then you can slow down, and if he still pulls you over the unit is off, so he can't try to trigger the device.
The "talking head" (a.k.a. expert) said the biggest problems with the unit are installation related. Many people don't install the unit properly so they have a reputation for being ineffective.
Regardless, for crying out loud, it's a 4500 pound Land Rover Discovery. I don't know how much faster than the posted limit I'd want to go with the lousy brakes and momentum they carry.

The only way that works is if the laser was pointed at the license plate- it takes all of one second to aim at the headlamp and re-shoot the laser.
A lot of the reviews you see on tv etc are not going to recreate 'real life' use of the equipment and they won't crucify advertisers. Detecting laser is simple- retransmitting light back to the laser receiver to confuse it isn't so easy. New laser speed systems are getting better at receiving only the type laser light that they transmit so they can't be messed with my IR LED's etc.
When I was doing speed enforcement stuff, we tried all our own detectors and stuff when we were bored. One guy bought a 'jammer' that did nothing, so we took it apart. It had a chunk of metal, some LED's and a circuit that looked a lot like a pager cicuit board- it must have been some kind of hoax.

i've got a cobra radar detector in my dI and it has saved my ass i don't know how many times. i would highly recomend it and it only cost about 90 bucks

I installed a whistler remote radar/laser detector in my truck- the antenna is behind the grille. I didn't install the laser module because it would only tell you after you are busted anyway. The display is hidden in the ash tray- close the ash tray and it's gone from view.
Hope you don't get hit one night by a trooper running specter while your the only one on the road and he's in a bad mood.

if it's passive (meaning it does not have a transmitter), it sends back a signal way under measurable. The "radar scramblers" is a scam just like Tornado.
Steve is right on every aspect of laser/radar detection and jamming. However, one can built a very stealthy radar jammer.

I had a BEL615 StIR in my DI mounted behind my grill.
For my DII, I got a BEL915 StIR and removed the antenna from it's plastic box, and mounted the antenna under by binacle cover. There's plenty of room in there behind the instrument cluster.
I did this mainly because it's a pain in the ass to get behind the grill (lesson learned!), but it's definately stealth. I've also got a V1 which I move between my other vehicles. I just mounted the V1 inside an old 'cd holder' and have the wire running out of it to a concealed display. Someone even makes a rearview mirror with a V1 display built into it.. it's expensive, though.

I saw a 'how to' article on how to build a display into a mirror- it's actually really easy. The hardest part was cutting the new mirror glass to fit- you have to buy the type that let light pass through from behind.
One thing I found is that radar detectors are really almost entirely useless unless you are on a lonely highway in the sticks. Even then, they usually leave the radar off until they see ya coming...
I think the last time I even turned mine on was a year ago.
Did you mean Spectre? Yeah- they work and work well, but they are also very expensinve and mostly only used near the borders of the state. If there's a group of cars, it's completely useless. VG-2 was easy to defeat, Spectre changed things.
