What is EMF？
Electromotive force will be generated when the current flows through the wire or when the electrical and electronic equipment is working. Electromotive force phenomenon exists in many places of our life and work.
DETECTION RANGE：
GREEN: "Normal" zone — Normal background Magnetic Field: 0 to 1.5 milliGauss
GREEN: " Low" zone- Low-Level Magnetic Field: 1.5 to 2.5 milliGauss
YELLOW: "Caution" zone-Mid-Level Magnetic Field: 2.5 to 10 milliGauss
ORANGE: "High" zone-high-Level Magnetic Field:10 to 20 milliGauss
RED: "Warning" zone-Extremely high Magnetic Field:20+milliGauss
OPERATION
1)Hold the EMF METER with your thumb on the switch
2) Point it toward the EMF source,then depress and hold down the switch(a short flash of the
LED's will occur)
3) The LED will indicate the range of the EMF at that level
4) Moving the device from side to side or rotating it may change the reading;the highest reading
is most accurate
5) Move closer or further away to the EMF source to determine the"Normal""zone as indicated-
by the Green LED

Works good, when there's a strange sound like foot steps I turn this on and it goes nuts and when you can't hear the noises anymore it goes back to green light. Is it Ghosts or just something to make you wonder...

I liked the fact that it came with the battery but would prefer a slide cover rather than the battery cover screwed on. It takes more time to change the battery when necessary

This is fantastic for investigating, and I know it works because it has the same exact high reading in my room as my other EMF reader - I thought my other one was possibly broken but now I know it just must be some high energy going on in my room lol ty for a steal- love it

My son insisted I buy him this. No idea if it does work but he enjoys it.
