Jo and Jemima were trained in geophysical magnetometry survey using our FM256 Fluxgate Gradiometer by Peter Masters of Cranfield University today. It's more complicated than resistivity! We spent a long time learning how to set up the machine so it had the same nanotesla (nT) reading N-S and E-W. The actual survey is relatively straightforward - just like for the resistivity RM85 but quicker because there aren't any probes to insert in and out of the ground.
We are running two Magnetometry courses this summer, and still have a few spaces on our second course on Saturday 20th July 2-5pm at Wicken Fen. You will need to have completed a course in Resistivity before attending this course. Booking through the website as usual.
