not really used the machine much, a few hours: just testing really (trying to work out how to use it.)
Not found anything 'old' apart from this nackered old bronze coin in the gravel of the tidal part of the Coquet, about the size of a modern penny. Most of the detail is worn away, being in a bit of an abrasive environment for a few hundred years. Anyway can see 'CARO' so perhaps Charles the 1st??
