EMF Meter,CHNADKS Upgrated 3-in-1 Rechargeable Electromagnetic Field Radiation Detector for EF RF MF，Handheld Digital EMF Detector with LCD for Home&Office EMF Inspections, and Ghost Hunting

Delightfully surprised by the quality of the product and thoughtfulness of the design. They even put markings on the case to indicate where the magnetic sensor and RF antennas are located (see photo). Excellent color display. Very intuitive menu. Perfect default settings; so it’s working the way you want right out of the box. Nice graphical display of readings over time. I keyed down on a nearby transmitter and the unit definitely registered the RF. I like how the magnetic sensor indicates N/S polarity, so it can also be used to align magnets for experiments. I tested it with several magnets. Attaching the lanyard wasn’t easy, because it doesn’t feed right through, but that’s incredibly minor. All in all, an amazing unit and a great value. I would definitely buy it again and will be recommending it to others.

Works good !

Works but if you don’t know how to read it’s a waste of money if you don’t teach yourself how to use it. Directions are garbage.

Ease of use, size, weight and accuracy.

So , great value and great accuracy . I don't believe more money would give me more accuracy. It says 120v on a 120v outlet , that's super accurate to me . It spots anything on. 120 without a ground far better than I was expecting . Cell phones while plugged in to a 120v are super bad for you . Don't use while plugged in to 120v ... great for spotting all unwanted magnetic fields , especially where we sleep . The functions are super easy to navigate and has USB-C I am more than satisfied and it now has a new home in my tool bag ... thanks for providing this product and thanks for fast delivery .

I bought two of these and compared and they are accurate!

This is a terrific unit. It works very well and is quite sensitive. I gave it one star because there is absolutely no documentation that comes with the unit. This is just corner cutting at the expense of the buyer. It's lazy. They didn't even bother to think up a name brand for their product. There isn't web site support. Complex electronic equipment should have documentation and support. The failure to provide these is both greedy and lazy.

Great
