Comments about Extech Instruments Electromagnetic Field (EMF) Meter:
This product quickly shows elevated electrical fields produced by such things as the electric stove, the fridge, the entrance mast, the furnace electrical box, etc. in your home. One to seriously look at is the electric field possibly created by your hairdryer-it could be enough to fry your brain cells through time!

Comments about Extech Instruments Electromagnetic Field (EMF) Meter:
I've found this product to be very accurate. While moving around and adjusting the 3-axis, the numbers fluctuate. However, once its been steadied and oriented correctly, the numbers don't change across measurements or time. This lets me know there is very little deviation in measurement.
As for ease of use, it's somewhat painful to twist your arm through all three dimensions to get a maximum reading (since this is a single axis meter), but for the price, it's about as good as you can get.

Comments about Extech Instruments Electromagnetic Field (EMF) Meter:
This is a great unit to find ghosts and to find what some would say ghost debunking... Their is so many things people think that they are being watched, getting headaches, hair standing up and just not feeling good... Well that is also caused by High EMF, well part of ghost hunting is to find this as well.. But when a spirit tries to manifest itself it pulls electricity out of the air and that causes a raise in EMF.. Thats why EMF meters are a great help in ghost hunting..
