    Default XTR-695 1.4 mile ka warning.

    This detector is very impressive for the price. I had a V1 but I couldn't deal with the falses through the city anymore. Not to mention my gf hated it with a passion. It had great detection though.

    I then decided on the 9500ix. And I was in heaven. Super quiet with great detection. Well it didn't take long for that baby to get jacked by the gf after she saw how quiet it was in the city. I was just like whatever I'll just get another one. That was 2 days ago.

    I haven't got around to ordering one yet. But I was in Walmart tonight looking around in the automotive section at the cobras and snickering to myself that some sucker was going to purchase one of those turds. And then it hit me that some of you guys reported the xtr695 in Walmart. And sure enough there was the last one sitting all by itself. I quickly snatched it and headed to my car and installed it on the spot. Once I fired it up it sounded like a game of laser tag. Pretty neat.

    Anyways the gf shows up and she to get a few things in wally world. So I wait for her while playing with my new toy. Finally she was finished and wanted to grab a bite to eat. I said ok and we head towards the highway. Sure enough I can't enjoy my new toy in peace the phone rings. I love her to death but sometimes I just want to be left alone.

    So while were on the phone she follows me in her car to the highway. I merge onto the highway and get over a lane and she pulls up beside me and jokingly said lets race. As soon as she said that the XTR-695 lit up ka 33.8. And I heard the 9500ix was silent for at least 1-2 seconds after the xtr-695 went off. I could not believe it that the XTR-695 alerted first. After the first ka alert I watched the odometer and it was 1.4 miles before we passed the leo sitting in the median. It was dark out so I couldn't tell exactly who it was.

    I was absolutely amazed how the XTR-695 performed. I though for sure that was just a fluke thing. But there are k band speed signs by my house and the XTR-695 alerts a solid 20-30 feet ahead of the 9500ix. This kband sign is on the opposite side of the road with big trees all down the median up to the sign. And all my escorts have struggled at this spot. 2 x50s and 9500ix. I don't know why either.

    Maybe my XTR-695 is just on the higher end of manufacturer variance. And my 9500ix is on the lower end. I don't know and I don't care. They are both great.

    All I can say is this Whistler is a keeper. This baby will defintaely see more action on my winshield.

    Sorry for the long story.

    My girl hates my V1 and hated my SRX because they go off for every pharmacy in town, but could at least appreciate their value when they detected a LEO. She couldn't stand all the constant beeping. It drove her nuts. Well, she saw how the GPS functionality of my 9500ix and 9500ci seriously reduced false alerts, now she wanted one. She wants to know where the LEOs are running radar, but does not want all the constant drama(her exact word) that my SRX and V1 have. Well, since my 9500ix had already stored all the false alerts, once we installed it in her car, it's quiet until it means business, which she loves.

    Ah see i was bit confused about the usage of "jacked".. I thought she didnt like the 9500 because it was too quiet, but now that i re-read, i see that she does like the quietness of it. All good.. my misunderstanding.

    So whatever happened to the "Flaws" of truelock where it would lockout a real K running cop in same place where you locked a false? Does this still happen?

    It's definitely still possible. The odds of it happening are remote however, as the 9500(c)i(x)'s histories have shown. A LEO sitting in just the right spot, accidentally having matched the false alert's frequency block and still not being able to be detected outside the lockout radius have proven to be a very tough set of circumstances for LEOs to reproduce.

    Knowing how Truelock works, I could definitely setup a scenario where Truelock would fail, but LEOs aren't trying to beat Truelock, they're trying to write citations. LEOs around me write plenty of citations just sitting there running C/O Ka band. All that extra work probably just seems pointless. Couple that with the fact that Applied Concepts(probably Kustom, Decatur and MPH do this also) is constantly telling police departments that almost none of the RDs out there can detect their radar helps also.

    Also, almost all of the new radar units sold are Ka band, so that's good news for us. I hardly ever see K band anymore and I never see X band. It's all Ka band and laser around here.

    Of course TrueLock will always run the risk of locking out a legit LEO at a known false location. However, I'm not saying that's a bad thing.

    In any introductory statistics course, one of the first paradoxes you study when exploring Bayes' rule is a situation where you have a detection scheme (an AIDS test and military airstrike radar are common examples) which alert 99% when a threat is present, and 1% of the time when no threat is present. For an unlikely event (such as encountering a real LEO shooting radar), the operator's belief that there's an alert present given the detection scheme is going off, is actually very low. If you want to look at the math of this paradox, this is a good writeup on it: http://en.wikipedia.org/wiki/Bayes_r...:_Drug_testing. Roughly put, given a test that is 99% accurate at determining something that has a 0.5% chance of happening, if the test shows positive, the chances of the event actually happening is around 33%.


    The question then becomes, is it more likely that:

    (A) The user is so tired of constant beeping, combined with the lack (or simply not caring enough to understand) of knowledge about the characteristics of a false alarm ramp-up vs a real encounter, that it leads to IGNORING every alert if there's even the slightest belief that there's a shopping center or "road sign" close by.

    (B) A police officer is running a K-band radar gun on the same 1/15th of the K-band spectrum at the same location as a door opener.


    I'd say (A) is a far more common scenario for the average user than (B). Would I recommend something like the V1 to the average person who just wants to avoid speeding tickets? NO! It beeps so much they'll probably toss it out the window before caring what the hell X or K band is. Would I recommend it to a nerdy enthusiast who wants to absolute best protection and is willing to put a lot of time into research and experience with the unit? Probably so -- I still strongly believe that having a knowledgeable person interpret the V1's alerts can yield just as good if not better accuracy at separating likely falses from legitimate threats. The problem is, the thing is beeping the whole time, your passengers are being annoyed, and if you are the driver and interpretor your attention is probably being diverted too much.

    Perfectly said. Well, at least the parts I understood.
