    Default What Causes Laser Falses?

    Please list all the possibilities that can cause laser falses? My V1 goes off on Laser many times where the RL is sleeping, or is it just smart enough to be quiet? Anyways, regardless of the debate, what are the possibilities of laser false alerts?

    Tailights
    Adaptive Cruise Control/Lane Assist
    Near airfields/airports you have LIDAR signals guiding planes (I think)

    V1 is more sensitive to laser than any other detector, thus it's also more sensitive to things that cause false alerts. Most common causes of laser falses include laser-assisted cruise controls (such as on Infinitis, some Lexuses and Volvos), neon brakelights on Chevy Trailblazer and GMC Envoy, some neon signs, some LED signs, the sun under certain circumstances, toll booth sensors.

    The Redline doesn't false to laser because it's not as sensitive as the V1.

    The Redline is just as sensitive as the V1. The V1's laser detection algorithms are designed to alert to just about any little blip of energy. Hence the V1 laser falses to anything, the sun, sun reflections, taillights, and strong RF noise sources. The Redline's detection algorithm is such that it is looking for a timed repeatable pulse train, that's what LIDAR guns emit. Hence the Redline isn't nearly as prone to falsing laser as the V1.

    Not true, if this were the case, the Redline would pick up scatter about as well as the V1, and that simply isn't the case.

    Once I get my RX65 back I'll make a scatter response comparison video of all my RDs.

    The Redline doesn't pick up 'scatter' as good as the V1 because the V1 has a huge convex lens in front of IR detection diodes that gives it a very wide field of view. The Redline's detection diodes are recessed in the case and that can and likely does limit the unit's field of view.

    Wouldn't that mean that the V1 IS more sensitive? I thought a blip was all you get with a scatter...?

    Wouldn't this also mean the V1 is more sensitive? Now I'm confused...

    My Redline failed to pick these up most of the time (although my 9500 ix did but nothing like what this video shows).

    That's a substantial difference. You get scatter saves with the V1 (although I would not rely on this given the limitations presented by LIDAR). You don't get nearly as many with other detectors, which often miss LIDAR outright. It is worth noting that there are plenty of videos that show the V1 not giving substantial warning time and occasionally failing to alert at all. However, there are numerous videos showing the Redline sitting quiet through laser and I can say I've seen it first hand with probably only 1 in 4 signals being detected at all, with no useful warning distance for the signals that it did alert to. For where I am at, I get sufficient range with my V1 in which I do not feel hard pressed to install my LI unit given I am about to buy a second car (which I will then install it on as it is a fast and pretty car).

    When the laser alert on a radar detector goes off it means 99.9% of the time you have already been clocked. So why not just turn off the RD laser alerts? Really, does it serve a purpose other than to pucker up your sphincter in anticipation of the ticket if you don't have a laser jammer? I can't stand chatty radar detectors. My RD seldom goes off so when it does I know I need to pay attention. For laser I just let my M47 take care of the problem. When the M47 goes off I really pay attention!

    See my above video. That is a 1.5 mile laser warning. They clock at about 300 feet. That is more than ample time and with the V1 you get laser saves...not just notification of laser tickets. I had scatter saves in my ix as well.
