"because I promote good practise within the detecting hobby"
Mr Brun, I'll tell you exactly how to do that.
Adhere to, and tell all your "for whatever reason we can't" heritage hero mates to adhere to the Code of Responsible Detecting laid out and signed last year by the major UK archaeological bodies plus both the detecting organisations, including its key provision to report all finds to PAS.
The idea that a small group within a small hobby can react within days to the publication of the stated wishes of the rest of society by unilaterally writing their OWN "alternative" code of responsibility for how THEY think the resource should be treated, in direct contravention of all professional archaeological opinion is risible and transparently self-serving.
IT AIN'T ROCKET SCIENCE. Behave as all archaeological opinion has laid out. "Responsibility" is whatever wider society says it is, not what YOU choose to say it is. That's the basis of civilisation and what distinguishes it from anarchy. Egg collecting is wrong. The Federation of UK Egg-Stealers' opinion is of zero significance since their stake in the resource is miniscule compared to the rest of us and their interest is clearly a self-interested and minority one. YOUR opinion isn't worth a bean. Society's IS.
Finally, for the leader of a group that is defying absolutely everyone else's view of conservation, both intellectually and practically, to come onto a conservation-minded forum and announce "I promote good practice" beggars belief. There is only ONE version of good practice. It is to do what everyone else has very clearly said is required. Just do it. Like some detectorists already do without the least inconvenience or complaint.
