Loading ...I’ve never tried holding it close to someone who I know has received the jab. What I do know is that it will give off a magnetic reading or alarm when you hold it close to a magnet or a device that has magnets like a speaker. Whether a person would set it off when you hold it close to them I have no idea. A good place to see what is will do is go close to the smart meter on your dwelling, or to the circuit breaker box..
Looking forward to hearing of your experience with it as you try it out. :o) I’ve gotten some real surprises carrying it around the community and seeing how many times it registers and where it appears the signals are coming from. Good hunting and keep us posted.
