Time Team have returned to the Roman fort at Brancaster in Norfolk. The geophysics team, lead by John Gater, have unfinished business at the site.

In this episode Helen Geake and Martyn Williams take you behind the scenes of the filming of a brand new Time Team programme. John and his team fire up their magnetrometry and GPR equipment to discover so much more about this amazing site. You'll hear conversations with John Gater, Jimmy Adcock, Stewart Ainsworth and Francis Pryor. Plus, Martyn gets a ride in the geophysics buggy to see how it all happens.

John's answering questions about geophysics from Time Team members on the podcast too. If you want to ask something about archaeology or Time Team itself on a future edition then why not become a Time Team member yourself? Head to patreon.com/timeteamofficial for everything you need to know.
