GQ GMC-600 Plus Geiger Counter Detector Dosimeter Alpha Beta Gamma XRay LND 7317 sensor tube

exactly what i was looking for.design could be better though. something more friendly to hold/point.comes with a nice little casealso, it is mini usb not even mini or usb-c :-(

I purchased this directly from GQ Electronics back in 2021 when these were fairly new and it was shipped all the way from Washington, USA. Shipping was expensive, but I had to make sure it arrived safely because it's a sensitive piece of equipment; this was proven by having the screen go completely blank after a few months of use. The ribbon cable that connects the screen to the unit had popped out despite not ever being dropped- but this was fairly easy to put back in.It's quite difficult to set up the server connection for uploading live data readings to the global map, sometimes it runs and sometimes it just refuses until the software is restarted. I find the global map does lag quite a bit when there's a lot of data displaying on the screen.As it's capable of detecting Alpha particles, this counter has a much higher "safe reading" where it will idle at around 40-50cpm for background radiation, whereas the GMC 320 will idle around 20cpm.The reading shown in the image is the counter picking up a Thorium-laced "5G Energy protection" sticker, inside a packaging envelope underneath a thick bedsheet, as you can see this is a very high reading for something that is concealed in many layers and the counter does a good job of picking it up.

It works fine. I’d like to be able to display cps and not just cpm. My understanding was it detects all three main decay types if not more, but I get a lower reading than with my Radiacode 103 which only detects gamma. There is no spectroscopy on this device.
