    Ok so does an older M47 extreme detect any type of lidar - including Poliscans and jenoptiks lasers?

    In essence won't any laser jammer system detect any 905nm laser?

    This question has NOTHING to do with jamming.

    Also with the different cpus for different regions (e.g US versus Australia cpus) - will they all detect all lidars, it's just the jamming for specific lidars that changes?

    Lastly can you use any M47 revision sensor with any region M47 cpu?

    Many thanks!

    That's a pretty old unit and probably wont pick up any of the new guns, let alone Poliscanes. IDK

    Laser isn't just laser, there are varying pulses that make them different and possibly undetectable, especially for an older jammer. The different CPU's probably offer different detection capabilities as well as jamming capabilities.

    If this has noting to do with jaming and everything to do with detection the solutions are ALP's or the V1.

    Here's the update for the M27/M47 that enables Vitronic PoliscanSpeed detection / jamming ;

    BLINDER HP-905 Software Upgrade Downloads

    There used to be a video by Blinder Australia showing an M47 jamming the fixed Poliscan on the Mitchell freeway at Stirling, but its been taken down.

    HP-905 will definately detect Poliscan, but Blinder admitted it won't jam it. As TraffiStar S350 is close to Poliscan, but lower power output, the 905 may detect it ?

    Blinder M47 definitely detects Poliscan as I've been using it for years - I only use the system for detection as the M47 are next to useless to jam about anything. And there is substantial evidence that nothing - not even ALP's jam Poliscans properly - enough to avoid a ticket. So I don't care about jamming.

    My logic is if the sensors are designed to pick up a 905nm laser wavelength, then regardless of what the series of pulses are (each lidar gun has a different sequence) it will detect the laser beam. So if someone out there knows the way they actually work and knows the answer that would be helpful.
    My understanding is all these systems pick up anything of a 905nm wavelength and then the system has to try and determine which gun it is and then send out the correct jamming sequence. But it alerts at the instant it detects anything at 905nm - that's what I believe to be the case, just looking for an expert that knows and can confirm it for me.

    Anyway my issue is I damaged my CPU of my Blinder M47 and need a new one. I am in Australia with an Australia CPU and can get a used Blinder M47 from the US, but its a US CPU - I just wanted to know/confirm that detection wise it'll work the same. And also if my current sensors/heads will work if I plug them into the US CPU - I'm assuming the sensors are all the same just with some different revisions.

    So while I could upgrade my entire system now - spending copious amounts of money in the process to buy an ALP or something like that - I just don't see the benefit if nothing jams the Poliscans or the newer Jenoptiks - I need to drive with confidence it works otherwise I may as well stay with a "detection only" system (like this crappy m47) as its served me well enough over the years.

    I appreciate the help!

    Thank you. However that's the HP-905 model not the M47 Extreme I was referring to.

    The link title is wrong, check out the 'M27 & M47 Upgrades' section on the page ;

    Ok thanks. I have the latest M47 firmware - which hasnt changed for seven years :D

    Furthermore - if you have a "AU" CPU then only the Australian firmware can be uploaded - similarly if you have a "US" CPU then only the US firmware will be allowed to upload to that CPU - I tried.

    Jammers don't detect just anything in the 905 nm range and alert to it like a RD does, since they are capable of jamming they must know specifically what gun is hitting them so they can fire back return pulses at the correct time. Older blinders used a lookup table it would see incoming pulses, lookup what was in the table for a response to those pulses and start firing back. So if it's a gun that isn't in the lookup tables it very well may not alert at all, blinders didn't usually see dragoneye or alert to it at all... some legacy jammers, LI i think, had an unknown gun option where it would attempt to jam a gun it didn't recognise as best it could in which case you might get an alert to something it doesn't have programmed in the database. Poliscans are tough, Alp can jam them as can a few other jammers, the issue is the angle they shoot them is very steep across the road, it's far enough off axis that unless you have the heads angled out it won't jam, but heads that are angled out don't provide good protection from all other laser threats so it's hard to get both threat types covered. Thankfully ALP is very sensitive so it will usually pickup the poliscan before you are in the kill zone and you will be able to slow down before you are in range.

    I think you are sooo wrong about ALP not successfully jamming Poliscan unit.
