So I heard about this radar scrambler and was wondering if anyone knows how effective they are. Here's the site: http://www.prt.net/Phazer-2.htm

Anyone own the Phazer II or Phantom 4? I would appriciate the feedback.

There's a site that debunks the claims that most of these companies make, I don't recall which one. In my opinion, police radar jamming is easily possible, it will just violate a bunch of FCC codes :p .

here's an Automobile magazine article on the subject

here

note that most of the Passive jammers actually increased the range at which you could be detected, likely due to the antenna being tuned for the optimum frequency.

Wow, that really disappoints. what a scam!

Anyone have any recommendations for a good radar detector?

I have the Escort 8500. It's saved me quite a few times. Many people like the Valentine V1 too.

Just drive like a grandma and you should be ok.

Do a search on Phaser and "scam" ... also check out radarreport.com (I think thats it)..also the escort site has a link to radar sites.. basically the phaser doesn't work-- its a joke.

And its not illegal because it doesn't emit any power, but a "FM" chirp (more bs).

Its a little refractor that supposed to reflect a "confusing" signal...

Now, how does a 1/2" non-powered "reflector" compete with 3000lbs of metal to a radar gun? You tell me.

Radar is easy to jam. We dont use radar anymore. It has mostly been switcher to laser. So these radar jammers are a waste of money. You will not jam a laser or get by a laser. Just trying to save you money

amartin

Laser jammers are out there and legal, though pricy.

Cattywampus

Lasers are designed to not jam. Unless it's a jet. A jammer needs to lock onto it's target first then jam its sensor. A laser is automatic and instant. We have tested them in laser school. They can not jam. They claim to scramble or jam the laser gun but its not reality

The Phazer does actually work -
if you aim at one with a radar gun in the store, it gets all 'confused', and that's how they sell 'em.
However, put the Phazer in one car and the gun in another more than ten feet away, and we are back to the "3000lb hunk of metal" scenario.

The Bel '9' series is very good, the Passport 85X is excellent.

...and it's good to know that jammers don't work, logically then, I can't be going as fast as it seemed, otherwise your Kustom Signals Pro Laser III would be locked on, right Officer?

So by the ex cops site you need a really good radar detector to slow you down before the laser can clock you? What if they only use laser to get your speed? That is really dumb. Not all ex-cops are really smart, many of the statements on that site definately sounded like BS. Probably gets money from the manufacturers to put BS out under a title ex cop??

devious12

So how do we beat your laser? :D

Aseras

I think the laser were getting jammed and they warn you they are picking something up and you slow down. Actual jammers like the scorpion ( only one I've seen work except a stealth rc2 something or other that fit in a semi of my dad's and was the size of a cooler ) are always on and they have a bypass or cool down where they deactivate by button. They are not designed to totally jam the cops.. they are designed to give you a few more seconds to hazardously slow down and cause a wreck because of the BS speed laws here in the country.

it's the most scientific I've seen so far.. I say we all buy a setup and test em

IMHO best bet is not to speed much out of "grace" and to keep your eyes open. You almost always see cops doing radar. 99% of the time they just want peeps to slow down and they can't do that hiding in the bushes.

Cattywampus

Go by at atleast 120mph and I will leave you alone. Just not worth the gas :D

therm8

That and leave off the front plate. The 8 looks to be a little more laser resistant than most cars, having no flat spots. And the best radar signals come from sharp angles (90 degree giving the highest reflection), of which the 8 doesn't have very many. I've noticed that I have to be alot closer to those speed displaying signs than everyone else, in order for it to display my speed. Though they are probably old school K-band frquency.

bxb40

Speed displaying signs are K-band on my detector. Laser is a ray of light hiting your car the moment the cop pulls the trigger. They do aim for something flat or at least lighter color. Either the plate or the headlight. You cannot jam it, it is too short of a pulse and a very narrow width. Only fog or rain will "jam" those. Your only chance is not to be the first car measured so your detector catched a small scattering when the cop measures someone in front of you (but if your RX8 comes along, I bet he will wait for you patiently). So at the least laser warning, you need to slow down quick because you'll most probably be the next target (unless you already are). Which is a very hazardous maneuver, the guy behind you will not have your RX8 brakes, and even then, the reaction time and his realization of the strength of your braking will have him hit your car. So........ very dangereous to try escape a laser gun. You get to chose between a fine and an accident you caused right in front of the cop (so guess how will be guilty for it?) Conclusion: speed only when not alone on the road, watch for any cars parked on the highway (police or unmarked).

You can't go wrong with a V1 (www.valentineone.com). The only one that detects from front and rear and gives you a display of the radar direction. It has also been rated as the best Laser detector. In most cases, that means you know 3 milliseconds earlier that you are about to get a ticket. -

No defense for instant on laser except advance warning from cars being pinged ahead. You must still drive sensibly, if there is no traffic ahead of you, you are a sitting duck no matter what the technology.

There are true radar jammers but you are getting into FCC/USC felonies since they emmit R.F.

The Blinder http://www.usblinder.com/ is said to be effective against Laser and only emmits light (No FCC issues). However more and more states are adopting laws against interfering with police speed measurement devices. Laser jammer sensors must have a line of sight and therefore are going to be visible.

There is a DIY here for V1 hardwire install to mirror power:

Have you guys had any problems with the new infinity series cars that have the intelligent cruise control that uses a lidar(laser) distancer to determine how far you are from any oncoming vehicle when using laser?

Here's a little write up by the BBC (i think) with a Dr. Michael Clarke (some British laser/radar expert)

[Erroneous distances

A wing mirror and a road sign doubled the distance recorded
The machine relies on the laser beam being reflected back at the gun.

However Dr Clark demonstrated what happens when that beam of light is deflected off another object before returning to the speed gun.

He set up a situation where the laser beam was hitting the wing mirror of a stationary car. He explains;

"What's actually happening is the device is sending out a laser beam that is hitting the wing mirror on the car, then it is being reflected onto the [roadside] sign … it's then coming back off the sign, back onto the wing mirror again and back into the receiver."

As the devices use a distance measurements to work out the speed of a car, Dr Clark believes that such reflections could cause erroneous speeds readings.

The slip effect

If the laser doesn't focus on the same area you can get the slip
As the gun calculates speed by measuring the changing distance to a car, if the beam of the gun is moved along the car while taking a reading, this could affect the results.

As Dr Clark explains; "This instrument doesn't know if it [the speed gun] is moving. So it started measuring a little bit further away down the vehicle, now it's a bit closer so it thinks there's a speed reading".

He then pans the speed camera down the side of a stationary car and clocks it doing 4mph.

"This is of course very relevant. If a policeman is pointing at a vehicle going by and he moves it across [the vehicle] then he will get an increased, or indeed a decreased, speed reading."

Dr Clark says that all laser speed guns suffers from the same problem so we thought we would give it a go on a wall with one of the latest guns used by the police: an LTI 20.20.

We clocked a stationary wall at 58mph - now that's motoring
By aiming at the wall and pulling the trigger whilst panning with the device we managed to get a reading of 58mph from the stationary wall - enough to get three points and a fine in urban areas.

Dr Clark has only been demonstrating the speed guns on stationary cars to us, but he says the problems could be worse in real-life situations;

"Because the car itself is moving they have to hold it very very closely on the same point on the vehicle otherwise they will get an erroneous speed reading."

In theory, this means that when doing a speed check, if the operator lets the measuring laser move across the side of a car during the speed check, then the length of the car could be added to the distance the machine uses to calculate the car's speed.

Laser guns typically take their series of measurements in about a third of a second. If a slip effect adds an extra couple of metres onto the distance you travel in a third of a second it can increase the speed registered by anything from an extra one to 30 mph.]

Interesting to say the least Particularly the 58mph wall :p

Cattywampus

Yes the new M45. I havent expierenced with it yet. We have had discussions about it during down time. Some deputies have said there is no difference. Some have said they dont pick it up at all. We havent tested it yet but the lead coordinator of the laser school owns one and we are wanting him to test it. I will find out oon as to why some can pick it up and others cant.

Ajax

The M45 isnt the only one now either. The FX45 and QX45 have it as well. It's slightly irritating as my V1 picks it up all the time :b
I think the problem is that infinity has the right idea and we're going to see it more and more in cars as a safety feature as the ability to pre-pressurize the breaks for sudden stops would probably save tons of lives.

Rotarian_SC

More importantly, how do we beat your VASCAR :p. Is that still widely used?

I've heard you can legally block lasers by installing certain devices on the front of your car that open your automatic garage door when you get near. Does that claim hold any truth?

Thetitanium8

I just drive the speed limit. Saves money and lives who would have thought :p
