View Full Version : will jammers work if laser is used from a high bridge?

Hello
I'm considering getting a jammer, either the M20 or Lidatek, leaning more towards the Lidatek coz i like the 5 second auto off feature.
But here in HK, its a common practice for the cops to shoot laser from bridges, down at approaching traffic.
From what i understand, sometimes a jammer won't work if it is not mounted properly and not pointing directly at the targeting gun. If mounted correctly, it will succesfully jam laser guns that are level to your car, but what if it's used from a high bridge, i.e. targeted at you from 20-30 degrees above you? Will it work?
P.s. the lidatek is just one head, is that enough for the whole front of a car?

With your VEIL job and laser sheild i think it should be good to have one transponder but some of us enthusiasts only settle for ultimate protection which is why i have 2 lidatek heads....
I think you should be fine with the one head, but you can always mount the on/off switch for the blinder in close reach so you can turn it off after you get to a certain speed
The high bridge shooting might be difficult for the jammer

The reason i'm getting it is because i want to remove the veil.
What about the bridge issue?

good to hear your finally wanting a jammer :D. although its illegal for you, its a very good idea to have one
i wouldnt remove the veil if i were you, i'd use both. most likely the cops are getting some code from your veil/lasershield already and with a jammer, it wont be any different. correct me if i'm wrong any of you GOL
i believe that the jammer will work just fine from a bridge. if i were you, i'd consider the blinder becauser its supposedly less likely to give jamming codes. what guns are you up against again? the LTI 20/20 and what else?

I am sure you have seen Outrun's videos with the saturn and you notice how the angle made it easy to get a lock? reverse the angle and you have a bridge situation
Without VEIL i would recommend the Dual LE-30, One is not cut it with no veil

Hey there! Whats up?
I wouldn't bother gettting a jammer if i wasn't removing the veil. The only reason i want it is coz i really miss my bright headlights from before. Veil does a great job, yes but it really messes up with my projector HIDs.
Sometimes i wonder if i got the older version of veil which was more dark....

Yeah, i saw the video of him with the saturn coming out of the tunnel and the blinder could not jam. I'm worried about the same thing because police always shoot laser from overhead bridges down onto approaching traffic here

I guess you could go with Just the blinder M20 judging by the results from the first GoL test

I personally don't trust any jammer without VEIL
Oh and since jammers are illegal when you want to be extra stealth you can hide your transponders with this thing

All jammers gave error codes on LTI and Stalker everytime at the GOL test.
most likely the cops are getting some code from your veil/lasershield already
Stalker gave an error targeting's Jim's car with no jammer. The gun seems to provide an error from just not being able to get a reading whether it's jammed or not.

thats an interesting thing to know, i assumed that it would give codes on most guns, just like any other jammer.
Blinder M-40 Xtreme
As portions of the Cannonball 2005 race was heading through a few states where laser jammers are illegal, it was decided to install a the Blinder laser jamming system as it is less likely than other models to produce a jamming code.
thats where i remember seeing that, dont know how much less likely it really is tho... a jammer is still a jammer

now, the big question is do the cops in HK know the different codes and what they mean? most over here in the US i have heard do not, they just try to lock on and if they cant, the look at their gun in bewilderment and then go lock onto another car :D. most of them either dont know what a jammer is, or that they even exist :lol:

Here in Hong Kong.......hardly anybody has jammers so if they get an error code they'll just get confused. I have a few friends who have had the guts to leave their m20 on and jam to gun, they didn't get pulled over.
I"m still hoping someone can answer me about the laser shooting from a bridge issue....

:shock: :shock: they've got some guts! i wouldn't even do that here where its legal. lol. i think you'd be more than safe getting a jammer in that case. in regards to the actual purpose of this thread...as long as the jammer is not hidden from the line of sight, it should be able to jam as far as i know. i remember someone was talking about mounting their blinders and jammertestwebmaster wanted them to mount them more foreward so that they would not be blocked for a circumstance like that. you'd have to ask jim or one of the other encyclopedias of enforcement and countermeasures (;)) to be sure

Yes...i was hoping one of them could answer.
I remember outrun made one video where his blinders were not effective against the police when his car was coming out of a tunnel coz the blinder would be pointing at the sky and not at the laser gun.
same thing in my situation. the blinder would be pointing straight at the road ahead, and not up at the bridge where the police is shooting from.
I"m leaning more towards a lidatek because I need the 5 second auto-turn off option. Other members of my family also drive the car and I dont want them to get in trouble if they jammed to gun.

considering you probably dont want to educate everyone that drives your car about your illegal devices, thats a very good idea. you wont need more than 5 seconds to slow down. if i were you and had the money, i'd get those A-Bond jammer hiders, those look pretty cool. dont know how you'd mount that tho, especially for jamming to a bridge

I think the only reason why the gun didn't get jammed was because of a high angle. The jammer probably responded but "missed" the the gun. One should query the validness of these measurements... :?
What is the closest a laser gun will work??? :shock:

Yo Dilip!
I would say we should wait for the Drive Smart "Defender 2" laser jammer... they have SPECIFICALLY designed this unit to fight the LTI guns. At least wait till they release it, and perhaps GoL has a chance to test it.
Head over to www.drive-smart.co.uk and take a look, they are real friendly, and drive-smart is in fact on this board already :D
I dont know about final pricing. Heck, you know I've got the Blinder M40 for my car anyway, and it has indeed saved me, and i consider it the best LED system out there. But if you're considering going for... dammit... what are the diode-type in the Lidatek (and also Defender2)... then I'd go with the Defender 2 if it tests to be good, just because they specifically desgined to fight the LTI guns.
As for the Veil... I remember when I put it on with you, it did make it darker, but I doubt it was any "older" than the current stuff, unless Veil guy has now made a completely transparent one?! :shock: It doesn't LOOK dark by just looking at it, but it does affect your HIDs. It didn't seem to affect my HIDs as much as your's though.
Perhaps you could compromise and wipe out a round bit on the lights just where the HIDs point out, so the laser signature is still reduced somewhat.

Hey whats up man?
I fixed my car! So...... when we going for a cruise?
You had the M40? I thought u had the M20! Anyhow.... has your blinders saved you whent he cops target you from a bridge above you?
I' really want to get one soon if it's within my financial capabilities. It is too difficult to just wipe out the veil just around the projector headlights, its almost impossible to accomplish without making that whole area look really really ugly.
No, the veil guy didnt make any new veil. I just read on the site somewhere that veil from last year, is darker than those released this year.

Yes, it has saved me from a bridge, but it was along Tolo Highway, I was going home from Luk Geng (Deer Neck) and you know how they have those passes/bridges over the highway? They were up there, and shot my car. I was quite far away when they shot... it took about 6-8 seconds to reach them going about 100Kmph. The Blinder warned and all that. I was going about 120-150Kmph before that i think, i dont remember exactly though.
I actually have the M40, but I never got around to fitting the rear blinders on my car, so I only have the front 2. I am thinking of selling my car to get the new Evo 9 :lol: So what I MIGHT do... and I haven't decided this yet, is either put 2 heads on the front, 1 on the rear, IN ADDITION i'll put a Drive Smart Defender 2 on the front... or otherwise, sell the Blinders. The rear 2 are actually new and still in the box! Or move the Blinder to my other car (the Levin). Not sure if anyone would be interested in my Blinders though.

Yes, i know what bridge you're talking about. Hey......i might be interested in the two blinders if i can afford it......... So it did work against laser from a bridge? hmm.... cool!
let me know when ur free!

It did work for me... of course, if the conditions are really bad, like you are going downhill slope, and the cops are high up on a tall overhead bridge, it might not be as good. But in this case, the Blinders have enough "field of view" to block their attack.
Do you plan to put any jammer on your rear as well? Or just planning for the front? I think they do shoot from the rear here, but i havent' had it happen to me... yet...

PRobably just the front, the rear is used but very seldom.....

The good thing is that too much angle is not good for them, becuase of the cosine effect, if the angle of the laser gun with respect to the trajectory path of the vehicle is too large, the gun will diplay a speed that is lower than the actual speed in proportion to the angle.
So if they shoot from an overhead pass, they will have to target the vehicle at a certain distance so as no to let the angle get too large or they won't get an appropiate reading.

Here is an overpass shot and this was a 9 second jam because you take about 5 seconds or so off the end jam time. Good video of overpass shot.
