    Its not that bad based on firmware updates etc undertaken this summer / fall to US models

    Well considering the ONLY guns used here are the LTI Ultralyte & occasionally LTI Marksman with PTs ranging from 300 - 996 ft I'd pass. Hell the laser mask is well cheaper and did just as well!

    On another note it is actually a Jammer and has no defence so I wouldn't fancy my chances. These LED jammers are very weak against the LTI guns especially without Veil for example.

    Not illegal to own but illegal to use.

    Sounds stupid cos it is stupid

    The legislation on these things was changed recently, they are now illegal to own aswell.

    I was in court recently (family law dont ask :() and a guy who pulled in at a Garda checkpoint (he pulled in, he was not pulled in by the guards) to report another car for dangerous driving, the car in question had already been stopped at the checkpoint. While talking to the plod they noticed that he had a radar dectector in the car and they did him for it. It was not a speed check so they would have no knowledge of whether he was using it or not.
    His solicitor made much of the good samaritan issue and said that " my client has never been in court before for a motoring offence and was trying to do his duty etc etc" at which point the judge remarked "we can now see why" (the whole court LOL'd) he got a hefty fine, cant remember the exact amount but it was over a grand. so beware!!!

    +1 Agreed.

    Try googling laser guns before you start slinging the insults around.

    Try using a laser gun before slinging comments around.

    Laser guns DO work at night time, The laws of physics do not change at sundown.

    It is true however that it can sometimes be harder to obtain a reading from a car when the laser is directed at its headlights on full beam, but it is not impossible.

    In short: radar / laser will work in daytime, nighttime, rain, sun,

    I think speed checks at night are dangerous for the gardai involved....true/ false?

    Anytime is a dangerous time for a traffic stop but night is not more so than day time. Actually the blue lights and the orange wand attached to the torch is more visible at night than it is during the daylight.

    What worried me most when I first saw it is that the legislation specifically states this. If it was an oversight, I can understand that, but I've no idea how someone thought it was a good idea to specifically say that, "The device does not need to be working properly to secure a conviction".
    I presume it was phrased to protect AGS in the course of their duties in case they got sued or whatever.

    Nonsense. You are making it up as you go along!

    Laser guns cannot be used and night and if I was targeted with one.. Cya in Court boys
    Cya in court as in you'll be done for speeding or Cya in court because you are taking on the system?

    2) Calibration? They don't show the certs for calibration? According to the suppliers of the Garda guns the calibration should be conducted "daily"
    "XXXSUPPLIERXXX recommends that this test be performed at regular intervals (daily). We also suggest
    a test area be permanently installed in a convenient location. The test area must establish a
    permanent known distance between a target and a shooting mark."
    I don't know where you sourced this but its irrelevant. The law as you have been told explicitly states that the equipment is presumed to be in perfect working order. It could be falling apart and legally you don't have a leg to stand on!
    WRONG AGAIN! Cosine error will always go in the drivers favour!

    Wasn't there a guy (university professor?) who challenged the law there on this basis and lost?

    I'm not sure,but the angle will always give a lower reading, trust me cosine error DOES go in the drivers favour every time and I've used an LTI ;).

    Maybe your think of Dr Michael Clarke chalenged the accuracy of the Laser with a method called the "slip effect" that could get higher readings from a flick of the wrist and also the use of the LIDAR gun in areas with reflective signing i.e road works etc

    Old GATSO RADAR ones - No...8 New MultaNova RADAR C Ones - Yes

    The Tripod (Lasercam / MicroDigicam) can work in the Dusk but has no flash for complete darkness.

    are they in operation yet ?

    and does the reflective surface of the registration plate reflect infra red ?

    cos i was thinkin thats how they gatso van would have worked in the dak that it would be able to see past the head lights? provding that they ont emit as much infra red!!!! (babbling ..... should have thought this through. i am sure there is method in my madness)

    Yes, In some cases better than normal light. The M50 Toll works that way. As regards IR Illumination, it would take a fair wattage of light to successfully capture a plate number IMO.
    I don't know where you sourced this but its irrelevant

    The EXPERTS that MADE the device.

    Would the Cosine not be a huge factor there? In the Drivers favour of course. The tripod is facing down, so if the the distance to the plate was say 150m, and the bridge was 30 ish M, surely, my Triganometry (12 degree's in this case), thats a big difference that gets bigger as your get further away?

    EDIT: If I ain't mistaken, E02 is a Jam code.

    ye should research this a bit more, most of the points are in correct!!

    I presume it would be a factor but the angle wouldn't be too severe and obviously they wouldn't be aiming further away as they need to snap the reg plate 12 degree would be about 3 - 6k off the actual reading so the majority of speeders would be nabbed.

    Nope not a JAM code but a measurement error. Its a common error on those guns, in this case its detecting an obstruction or the target has moved out of range

    Could someone in the know here please give a rough indication of what percentage of the speed detectors the Guards use, i.e laser and radar?

    And on which roads would they be most commonly used? i.e. laser on motorway etc.

    Thanks!

    Laser would be the main tool used - LTI Marksman & LTI Ultralyte (A few have Lasercam / Microdigicam to snap your plate). Its Ireland so be sure to see them on the motorway or on the slips shooting cars from the rear :eek: NASTY!

    VANS - 3 or 4 GATSOMETER vans (Low Powered K Band RADAR) & 8 X MulaNova Radar C (Low Powered Vertically Polarised K Band RADAR), And there's a van with a Laser operator on board as well. They park the GATSO up the M1 80k before the airport alot. - SHOCKING :mad:
