The Portable Antiquities Scheme (PAS) is a national programme run by the British Museum in partnership with local bodies; in Wiltshire these are Salisbury Museum, Wiltshire Museum, Wiltshire Council and Swindon Museum and Art Gallery. The primary aims of the scheme are to provide a framework by which members of the public can identify and record finds of potential archaeological significance, as well as to encourage awareness of archaeological issues and best archaeological practice. Whilst the scheme is available to everyone, from field walkers to builders, by the nature of their hobby Metal Detectorists find the majority of the archaeological artefacts we record onto our database; and it is our job to help those engaged in the hobby record as much archaeological information as they can, while also minimising disturbance of in situ archaeological remains.
Metal detecting as a hobby is actually highly comparable to fishing and, anecdotally, I have noticed there does seem to be a great deal of overlap between the two groups. Both hobbies are relatively solitary affairs which can require great deals of patience – they both also exploit a resource in our environment, but this is where the similarities begin to end. Whereas fishing is carefully licenced and managed in order to ensure that the exploitation of our river’s fish is sustainable, there is no such monitoring of the archaeological record.
Crucially, and unlike fish, the archaeological record cannot repopulate itself, once a deposit is disturbed and/or artefact removed, the context is lost for good. This is why it is imperative that detectorists behave responsibly as they exploit this resource which, ultimately, belongs to everyone.
Legally speaking, detectorists in England and Wales are only required to report objects which meet the criteria of the Treasure Act 1996, this is a very specifically worded and narrow set of criteria which frequently miss nationally important finds; a recent example has obviously been the Gloucestershire Dog hoard, but more locally this narrow definition has missed a large hoard of Roman pewter, containing a rare and well preserved tank, thankfully reported by the finder. There is more to detecting responsibly than simply making me aware of unusual finds however, and the perception that I would only be interested in nicer finds is something I often run up against.
