Geosight
I am owner of the geophysical firm called Geosight, and I have been doing geophysical surveys at archaeological sites since 1970. While I apply many different instruments to my surveys, I have emphasized ground-penetrating radar, magnetic, and EM conductivity/susceptibility surveys. My field work has been done in several dozen countries, and I am starting to learn a little about archaeology.
