The handle for the Vanta GX is hidden under the front hood. It is just designed nicely not to stick out. The gold detection and karating of this unit work well too. I have another video where I shoot certified Reference materials with pretty darn good numbers. Plating detection on any XRF is limited to a depth of around 20um. This is more a limit of XRF technology and not a particular instrument. The Vanta GX is available in both pin-diode and Silicon Drift Detector (SDD).

I watched a movie with reference samples, and indeed, the measurements are very accurate. Was the device you used with Si-PIN or SDD detector? I think the handle should be for opening because when closing, you touch the external part of the housing with fingers and this part is painted. After a year of intensive use, the paint may wear off. We are talking about a device that costs around $25,000, not $1,000, so... Also, could you provide some insights into the camera quality? Is the image sharp and clear? In the video, it seems slightly blurry. These are high-end devices, and in my opinion, every detail should be perfected to achieve excellence.

25k for a XRF is low end FYI unless you're talking about chinese etc etc... High end looking at 50-100k, this is for the built for market required. Looks great in my shop, paint I can't see ever wearing.

@@Maddoxd-vx9xs In 2024, I would expect pricing between $20,000-25,000 USD for this type of XRF. I recommend staying with an American company as the support and quality is much higher. While Alloy Geek does not work for any of these manufacturers, we do think this price point is good for most small businesses including jewelers.

The device test, in my opinion, is not good. People who buy a spectrometer for around $25,000 mostly test gold, so you should focus on various gold samples in different types of jewelry and how the device performs in detecting gold-plated items. I had the chance to test an old Olympus GoldXpert, and it detected a gold Krugerrand as gold-plated. I'm not sure about this model, but it's exactly the same as the Vanta gun, a Linux-based system. So, perhaps they've improved something in detecting gold-plated items because that wasn't good in the old GoldXpert. Besides, it's unknown whether this version has the SDD or Si Pin detector. This should also be mentioned in the test. The higher purity in the center of the emblem probably results from significantly fewer impurities there, or it could be made from a different piece of gold. If the detector picks up dirt and tiny metal shavings that disrupt the measurement, it can show a lower reading. This surely has nothing to do with gravity. Moreover, before measurement, the tested fragment should be thoroughly cleaned if precise measurements are desired. Lastly, a device of this type should have a handle for opening, as seen in Fischer devices. Olympus didn't excel in this aspect, opting for the top part of the field version cover for the Vanta gun and presenting it as a new device.
