@RichardHarris123 I just look for a relative increase or decrease as it passes over the watch, not an absolute value. It it doesn't change much passing over the watch, than I conclude little or no magnetism, if I see the value jump from the background number, than I know I have a problem

How accurate is it? Does it take the earths magnetic field into account, what is an acceptable reading? -
I watched the video review of the Chinese version of Elma's demagnetizer and I am skeptical about the use of a compass to measure magnetism. To measure magnetism I use a metal detector app on my iPhone. There are many such apps and they generally work well. The problem with using a compass is that they are not very sensitive while the apps detect the slightest trace of magnetism.
