DCH85 with "good conditions" works!!!!! i am sure. About GG i am not sure.

This is what I thought Geo but when the gg reads mV this is voltage of the electromagnetic field which probably exists in some place where the ferrite antenna points.
I would like to use a DCH85 even if it works only under special conditions.
The thing is I am confused whith the different DCH85 models that mineoro came up throughout the years.
Do they both work allright? Which one do you suggest? Work in the same principle?
