Seeking the JM20 Pro RF detector

Hi there,

So a couple of older videos have mentioned this JM20 Pro for detecting trackers in someone's body.

I tried to find it online, and one site looked like it was the right kind of device, but had no price & I think they are defunct. The others had this cable looking thing which I'm pretty sure has nothing to do with the device that you hold up to your body to scan.

Does anyone know what the differences are and where I can get this device? Price is important to me.

Also, I have an RF detector (I think that's what I have), but I'm not sure that's the same type of device that can detect trackers, especially if they are nanotech.

Thanks
 
Hello, Welcome to ASR!

ASR is focused on audio measurements and discussions of audio equipment: speakers, amplifiers, DACs, turntables, audio tape, music in movies, and music we play.

If you look at the main page, you can see our topic areas. One of our unique areas is audio test reviews under "Reviews."

Maybe an internet search led you here because there is discussion of a JM20 USB headphone dongle DAC. That is completely different than the divice you mention. Looking at your device online in "spy stores" a better more professional option would be a SeeSii TinySA Ultra+ ZS406, with a set of frequency-specific antennas. There are many online forums about RF, DIY RF, and RF hacking which would be a better source than ASR. I would ask what technology is real and proven to exist. There is a lot of bad completely fictional information out there.

I managed part of one of the 4G standards development groups. So I'm technical on RF systems.

Yeh I had a feeling this wasn't the right forum & yes, that's what led me here, but I don't understand why it's got the same exact name if it's not even remotely what the other one does. Does different hardware often have the same name?

I'm not tech tech savvy although I know some things, so I don't even know what that headphone dongle is for or what it does. LOL

So I should search for SeeSii TinySA Ultra+ ZS406?

Well this isn't about RF hacking. I'm not even sure what that means unless you mean cell towers.

Thanks, much appreciated.
