Hi guys, today I saw on ebay this detector of electric and magnetic fields where the sensitivity range goes from 0.01uT to 19.99uT. I do not have experience about these values if it is or is not sensitive to search for buried iron objects. I await your comments. Charles

Magnetic field magnitude at the Earth's surface ranges from 25 to 65 microteslas.
To detect iron you would be looking for distortions in the Earth's field.
A little googling and reading about magnetic field surveys should give you the answers. -
It's for AC fields, not DC fields. Won't work at all for buried iron.Comment
