Laws requiring permission from the land owner to use a metal detector and dig vs. needing such permission on your own land seems very different IMO. The English law seems focused on preventing trespassing and digging holes in people's yards, and also to make sure the land owner gets compensated for anything of value found. (e.g. from the link by madax below: In England "An experienced detectorist, Davies would have known he was entitled to half of the proceeds of legal sale of the treasure, instead choosing to deprive the landowner and public by stealing this exceptional and significant treasure.") The Irish law seems focused on preventing anything from being found.
