K40 Releases the Platinum100

K40 is releasing a new windshield mount radar detector called the K40 Platinum100 ($470). It offers a bunch of improvements over their previous K40 RLS2 ($400) including longer range and several key new features.

This is like a windshield mount version of their custom installed Platinum360, but without the arrows. These new “Platinum” series detectors share the same underlying platform as the Uniden DFR series detectors. Thanks to the addition of an LNA (low noise amplifier) for better performance, instead of sharing the same platform as the Uniden DFR5 ($99), these detectors now share the same platform as the Uniden DFR7 ($169) / Uniden DFR9 ($235).

(All these detectors are built by Attowave, a South Korean radar detector manufacturer, which is why they share many of the same features and underlying hardware.) Fortunately there are number of improvements over the DFR series detectors though.

K40 Platinum100 Features & Highlights

So compared to their previous RLS2, there’s a lot of nice new updates. The Platinum100 gives us longer range, a nicer display, MultaRadar detection support, plus the ability to integrate with a remote control and K40’s laser jammers.

Now that said, I don’t think there’s really that much appeal to this detector. At the end of the day, at $470, it’s a tough sell compared to the competition.

Is the K40 Platinum100 Worth It?

For example, the Uniden DFR9 ($235) shares the same detection platform, but the Platinum100 costs twice the price. To be fair, it does add MultaRadar detection which is nice. You do oddly lose RLC/speedcam alerting capabilities, but you gain the ability to tie into K40’s laser jammers or remote control. I’ve found K40’s laser jammers to be the worst performing on their market and personally I think $160 for a wireless remote control (or $90 if bundled with the detector) that duplicates the buttons already available on the detector doesn’t make a whole lot of sense.

Alternatively you can pick up a Uniden R3 ($300) and save $170. The R3 adds in the MRCD support, plus it also offers longer range than the K40, better BSM filtering, RLC/speedcam alerts, and you still save a bunch of cash.

Heck, go get an Escort Max 3 ($400) which has better performance and filtering, autolockouts, MRCD, Bluetooth, and cloud alerts. For $500, you can get a Uniden R7 or Valentine 1 Gen2 which offer better performance and BSM filtering plus arrows. I just don’t see the appeal of the Platinum100, price-wise. As usual, that looks to be yet another overpriced underperformer from K40.

So as you can see, this detector doesn’t really have much of an appeal if you’re searching for the best. I may pick one up at some point to test it, properly review it, and compare it head-to-head along with the other options, but it’s not a detector I’m particularly interested in or excited about.

    K40 made a pretty nice detector way back in the day. It was a must have for truckers and outperformed the original Escort, Fuzzbuster, Whistler, etc. But that was 30+ years ago.

    My R3 is better for about $170 less. What does the remote really do for the extra $$$? No red light or speed cam info. K 40 and Rocky Mtn Radar over priced and under performing.

    What type of power connector does this radar detector have?

    @VortexRadar by chance would you make a video about the most rugged & reliable power connectors available to radar detectors?

    The most common power connector I have seen used is the RJ11 which is poor design and unreliable connector due to the locking tab breaks off frequently and new power adapters need to be purchased, very annoying.

    Keep up the great work!

  1. >> “2 digit freq. display”.
    From the photos you’ve posted, it looks like it is 4 digits including two decimal places.

    In my opinion, the remote control is a nice idea, but I’d never pay more than $29 USD for it. I think that for them to ask $180 USD is just absurd.

    Why haven’t you tested it?
    Why doesn’t any other company have k filters for all the cars on the road that have auto cruise controls and auto braking? Why doesn’t anyone else have a ticket guarantee?

    How do you know it is not the best if you haven’t tested it?

    VW makes/owns $30k golfs…$200k porsche…and Bugatti.
    So simply saying its platform is made by the same people as “joe smo” doesn’t mean its the same.

    sdrawkbab—-Most people will $50.00 for an apple video cable…LOL…???…LOL

    If the k40 are so Bad why is it that the porsche dealers offered them on the lot?
    p.s. what diffuser was the last one you tested. I can’t find anything youve tested that is new.

    1. I have since tested and reviewed the Platinum 100. You can see the full review here.

      Just like all the previous K40 products I’ve tested over the years, the Platinum 100 turns out to be an overpriced underperformer as well, easily one of the worst detectors in its class. That’s not a surprise though given the platform it’s based on, as well as the features it offers and the features it lacks. Towards the end of the video I also address why I believe some installers offer them.

      The last defuser of theirs I’ve tested is their Defuser Optix, their latest and greatest. Here’s my review of the Defuser Optix and here’s how it compares to the competition.

    I used to work at a CB shop in the late 70’s and early 80’s. Whistler and Fuzz Buster were the top brands. Then K40 detectors came out. They already had top notch CB radio antennas, but their detectors were on another level compared to anything else. We sold boat loads of them and they performed very well. But new and improved radar showed up, and new brands of detectors came out and K40 never stepped up their game. By the early 90’s you couldn’t give one away. It looks like not much has changed.
