Can you tell me are members covered by public liability insurance, not the FID or MCMD that only covers you for farm damage to the farm, are the local FLO informed about these events as there are over 50 people and must have at least 12 weeks notice. As a farmer I would not be happy letting anyone one on my farm apart from a local club, you seem to be letting anyone on your digs and you don't even know them. How do you know your not letting night hawkers on the land iv had murders with them.
Its Natural England that administer the derogation for large scale detecting events on stewardship land.
Its the NCMD (National Council for Metal Detecting).
I did mention stewardship earlier in this thread but I was "being misleading" so I was told!!
