If someone asks you for permission to use a metal detector on your scheduled monument, you should inform them that the site is scheduled and that they need consent from Cadw.
Os bydd rhywun yn gofyn ichi am ganiatâd i ddefnyddio synhwyrydd metel ar eich heneb gofrestredig, dylech esbonio fod y safle wedi’i gofrestru a bod angen gofyn i Cadw am gydsyniad.
