Mark and his colleagues are currently involved in a project with the National Museum of Wales investigating Bronze Age sites in the Vale of Glamorgan - and metal detectorists are an integral part of the team.
“Metal detectorists are very useful,” he explains, “they can mark sites and check for metal objects in a dug trench, which is an incredibly useful tool. I don’t think archaeologists should undertake digs without them.”
For the November 27 Finds Roadshow, Mark will be based at the Wrexham County Borough Museum, not far from the find location of the Burton Hoard.
“It’s good that we’re in Wrexham,” he says, “because it’s where a lot of these great treasure hoards have been found. I’ve contacted the metal detecting clubs in the area and they will be there displaying some of their finds, which is also good because it gives them a sense of ownership.”
The Finds Roadshow takes place between 11am and 3pm and includes hands-on archaeological activities for younger children including a mini dig. Free copies of the Portable Antiquities Scheme annual report will be available together with the first of a series of newsletters compiled by Mark containing more information on PAS reported finds in Wales.
In the coming week more FLOs will be telling us about their experiences of administering the PAS and revealing some of the amazing finds they have encountered - giving an insight into the archaeological landscape that surrounds us.
The series started in Essex where we talked to Finds Liaison Officer Caroline McDonald.
In Devon Nicky Powell revealed some of the things that land on the desk of an FLO.
Shropshire and Herefordshire FLO Peter Reavill explained the historical topography of the Welsh Marches.
Simon Holmes North and East Yorkshire expounded the virtues of 'community archaeology'.
In Oxfordshire and Berkshire Kate Sutton told us about the vast range of finds coming through the scheme.
