It is primarily focused on private metal detectorists who through their hobby regularly discover artefacts that would otherwise go unrecorded. Members of the public can also report objects they have found and finds of non-metallic objects are also covered by the scheme. Finds that legally constitute treasure are dealt with through the Treasure Act 1996. This however concentrates on precious metals, prehistoric base metal, and finds in association with them. Non-prehistoric base metal and non-metal finds would not be recognised as treasure and therefore be unrecorded. The PAS exists to fill this gap.
