B3any Posted April 18, 2003 Share Posted April 18, 2003 Got my Laser Jammer fitted today fella's with the minimum of fuss, (obviously for my garage door) Obviously its a difficult thing to try and if it dont work your fooked, but it recommends that you try it wioth a remote control from your TV which it works with so i'm hopeful, i'll let you know if i get a genuine occasion where it works. Heres a clip of how they work. " When the LRC acquires a Laser gun, it immediately returns a 5 second signal, gives the driiver a visual warning and emits 100DB audible alert. For 5 seconds the laser gun will not produce a speed rating, more than enought time to adjust your speed, then the diode shuts down and the jammer acts as a passive detector for the next 60 seconds, after the 60 secs its good to go again. The Laser jammer transmits a powerful laser singal at the same wavelength the laser guns are designed to receive. Due to the strength and timing of LRC's signal the laser gun ignores its reflections and tries unsuccesfully to calculate speed" Quote Link to comment Share on other sites More sharing options...
TOKYO Posted April 18, 2003 Share Posted April 18, 2003 I purchased a Roadpilot last week, and it is the nuts, and am thinking of getting a jammer. Which one do you have if you don't mind me asking. Glen Quote Link to comment Share on other sites More sharing options...
B3any Posted April 18, 2003 Author Share Posted April 18, 2003 Target LRC100, latest and greatest apparently, Ive got the Snoopre S6 Neo Glen, there great for Gatso's but too late for Lasers, heres a review on the jammer i just bought. http://www.ukspeedtraps.co.uk/lrc100.htm Quote Link to comment Share on other sites More sharing options...
TOKYO Posted April 18, 2003 Share Posted April 18, 2003 as thats what I was recommended even by the guys who supplied the roadpilot. Thanks for the link. Glen Quote Link to comment Share on other sites More sharing options...
Wolf Posted April 19, 2003 Share Posted April 19, 2003 Sorry, thicky question here but I thought a laser speed gun actually fired a laser beam (much like a laser range finder etc) - so how does the jammer manage to detect source and angle and fire a beam back through a possible 180 degree forward radius and probably a 20 degree vertical radius (i.e. the copper could be anywhere in front of you) ...... or have I got the concept totally wrong?

B3any Posted April 19, 2003 Author Share Posted April 19, 2003 Wolf read the review on it, its by an independent guy who has got more info on speedtraps than a speedtrap itself. Quote Link to comment Share on other sites More sharing options...

Glen Tested it out last night Glen, (using a remote control) certainly works, you'd never not hear the thing, its very high pitched and loud, managed to hide the unit very well, and hide the switch mechanism. i'm good to go, cant wait to jam my 1st laser....

Steve W Posted April 19, 2003 Share Posted April 19, 2003 RADAR is completely different to LASER....... RADAR is (to all intents) multi-directional = a wide "WAVE" (?) ( or, like a radio signal, if you like ) LASER is UNI-directional = a "BEAM" ( or, like an EXTREMELY narrow torch beam, if you like) It should be relatively easy to re-transmit a RADAR signal as you don't have to point it EXACTLY at the point of origin. To DETECT and then re-transmit a Single-Point LASER signal is an entirely different ballgame.... ! ! ! [just as Wolf says, NOT impossible, but you'd need a laser 'gun' in the unit capable of MOVING and firing to the point of origin ! ! ? ?] The older 'guns' were/are RADAR, the newer 'guns' are LASER (so they can be sure they are measuring a PARTICULAR vehicle in a group) OR, I COULD HAVE THE PRINCIPLES ENTIRELY WRONG ! ? .......... over to the eggheads... ! ! !

B3any Posted April 19, 2003 Author Share Posted April 19, 2003 Heres a bit of the info i have - "The LRC 100 still uses the gallium arsenide laser-diode -the same found in police laser guns and is still the only laser jammer to use it, other jammers often just use a lower cost diode that can still do the job but take more energy to do so and can suffer power fade over time. The LRC 100 detects the laser beam from the police speedtrap and then fires back a laser signal in the police signal this then prevents the laser gun's computer from computing the speed reading."

Steve W Posted April 19, 2003 Share Posted April 19, 2003 It might very well do exactly what they claim ! Just doesn't tie-up with how I thought the Lasers worked, IF they're like any 'normal' laser then it will only 'hit' one point on the car - if that point's not the Jammer detector, how will it ever see it ? [ thought it was like the lasers used by Surveyors... you can't see that beam until you're actually staring STRAIGHT at it (by which time it's ripping nicely into your retina ! ! - not sure how they get away with them to be honest ? ?) ] Perhaps the laser 'guns' use a spread-out (?) laser beam ! (but then, it wouldn't really be much of a laser then) JUST be a bit wary of relying on it..... STILL watch out for the Jolly-Fat-6ft-geeza-with-the BRIGHT- YELLOW-JACKET-ON ! ! OR, the 2 geezas pointing a LARGE-GUN-TYPE-OBJECT at you off a bridge over the motorway ! ! It's always worked for me ! !

Thorin Posted April 19, 2003 Share Posted April 19, 2003 I don't think it's a case of the jammer having to move around in order to point the laser back towards PC Plod, I think it probably just fires out beams all over the place in a forward direction. Probably why it can only jam for 5 seconds too. Quote Link to comment Share on other sites More sharing options...
dude Posted April 19, 2003 Share Posted April 19, 2003 The guy that runs the site has a collection of all the current speed guns and will come and test the jammer is functioning , or you can go to him . John:flame Dev Quote Link to comment Share on other sites More sharing options...

Adam W Posted April 20, 2003 Share Posted April 20, 2003 The police laser beam is like a fine beam, but when the jammer goes off it's like a floodlight that fires off in all directions and swamps the signal from the bounced police beam. Quote Link to comment Share on other sites More sharing options...
Steve W Posted April 20, 2003 Share Posted April 20, 2003 SO, how does the DETECTOR see the fine beam ? ? unless it's 'always' fired at a 'typical' spot... do the pigglet-wigglets HAVE to aim at 1 particular place on a car ? Can't it be done on a corner/wing, can it be done from the side ? I can see it hitting, say, a grill and the detector being there- abouts and the emitter pointing 'mostly' at about, say, 30 degrees from the straight-ahead ie. where fuzzy-bear's most likely to be... but, if he's NOT ? ? ? ? JUST, throwing up suggestions ya' realise, NO KNOWLEDGE AT ALL, just wouldn't like to see anyone RELYING on it till you KNOW it's capabilities (NOT just what Mr. Seller says:sly: - tell him to test it from ALL angles etc. ! ! !- if it STILL does it's THANG = brilliant !)

Wolf Posted April 20, 2003 Share Posted April 20, 2003 Adam Sorry, but how does a laser fire off in all directions - if the beam is unfocussed and so wide it can only reach a few feet from the source as it scatters - in fact to get a few feet would take a very powerful laser... Any closet physics professors want to jump in and clear this up? Quote Link to comment Share on other sites More sharing options...

Asim Posted April 20, 2003 Share Posted April 20, 2003 Hey guys, if you look at the speedtrap site our man has mentioned earlier, you should also note that some guy recently became the first person to be prosecuted for obstructing the law by using a laser jammer! And as far as I am aware Radar Detectors are not illegal to own, but are illegal to use? So unless the police are in the car while you are using it they can't prove you were using it? But then again why does Argos sell the Snooper??? Can anyone clarify? And does anyone know which aftermarket exhaust will give the highest Bhp increase on an NA 93 Supra ???

B3any Posted April 20, 2003 Author Share Posted April 20, 2003 Ok heres technical info i've found on the Laser gun for you especially steve:D " A laser gun works best when aimed at highly reflective surfaces such as headlights or reg plates. Its internal computer measure the time it takes for the pulse it sent out to return. After doing this many times, it can display how the target vechiles disrance is changing with time (speed). A laser gun usually transmit about 100 individual pulses of infared light in the one third of a second it takes to calculate a vehicles speed. With pinpoint accuracy, its narrow beam can pick out 1 vehicle in a group, this means the laser guns beam is normally 3-4 feet wide at a distance of 1000Ft. Laser guns ususally target between 600-1200ft. Targeting vehicles greater than 1000ft is difficult " Does that clear things up? Quote Link to comment Share on other sites More sharing options...
