JVSURF EMF Meter Magnetic Field Detector, 2024 Upgraded Hand-held Digital LCD EMF Detector, EMF Meter Ghost Hunting Equipment Tester for Indoor & Outdoor Inspections

I ordered this EMF meter for a friend who likes to go off ghost hunting and is building a toolkist for doing this. It's quite low-end, as you'd expect for the price (£21.99 at time of review): somewhat cheaply made and finished. I certainly wouldn't want to rely on it for any sort of professional-level EMF detection. However, it was reliably detecting various EMFs I tested it with, such as around my computer and electrical wiring in the old cottage I live in. This cottage is reputed to be haunted, but I've yet to see or feel anything out of the ordinary - if I pick up anything with this meter I'll update the review to say!To be frank, I think this is probably more for the new entusiast than for the serious user. But if you - or someone you know - is keen on trying it out with a bit of ghost hunting, it works and is relatively affordable.

I couldn't really regard a cheap device like this to be capable of serious measurement of EMF, a professional scientific device would be fully calibrated to ensure accuracy and account for any EMF that the device itself generates. Also, since this device indicates only an imprecise level instead of using a digital display, I doubt it would even try to highly accurate.Unlike another one I already have, which is of a different design, this one did not respond at all to live powered cables, sockets or many other electrical devices. It did go off in very specific locations, and responded strongly to certain devices but not to others. So really I see this more as a bit of curiosity rather than for actual diagnostic use. Photos are for comparison of the two meters, put next to a tablet and an old clock radio, with differing results from the pair. This one being the one that fails to register in many cases where the other does.The "ghost hunting" claim is just silly, which credible scientific publication has linked paranormal activity to EMF? And its not as though this thing will give an indication when just waving about in the middle of a room, it has to be right up next to things to do anything. A 9V battery was fitted, so could it could be used right away. Also, the LEDs used for this are far too bright.

My child enjoys it and now believes he's a ghost hunter. The detector seems flimsy, constructed from inexpensive plastic, and it detects EMF throughout my house—even my Apple Watch emits a significant amount of EMF.
