What you are missing is the story of Archaeology Rheesearch, which basically undertakes community based geophysics in South Cambridgeshire in the UK
Or to put it another way, we are a group of landscape archaeologists who go out and help community groups with their archaeological projects by doing geophysical surveys
using a magnetometer or resistivity techniques to visualise archaeological features under the ground. There are lots of photos on the site and animations
of us using our Bartington magnetometer or TRCIA resistance meter.
