10. Basic Operation
10.1 Code of Conduct
Do not interfere with archaeological sites or ancient monuments. Join your local archaeological
society if you are interested in ancient history.
Do not leave a mess. Use a sharpened trowel or knife to cut a neat circle or triangle, extract the
object and carefully replace the soil and the grass.
Help keep your country tidy. Bottle tops, silver paper and tin cans belong in a waste bin. Rusty iron
and other scrap should be collected and taken to a specialized company for further handling.
Do not trespass: ask permission before venturing onto private property.
Report all historical finds to the local museum or government and get expert help if you accidentally
discover a site of archaeological interest.
Be very careful if you discover any live ammunition or any lethal object such as an unexploded mine.
Do not touch the object! Mark the site carefully and report the find at once to the local police.
Do not leave gates open when crossing fields and do not damage crops or frighten animals.
Try to get along with any other detectorist you may meet. There is much to be learnt from
experienced users.
Always obey local laws and regulations. Contact your local government for more information.
It is illegal for anyone to use a metal detector on a scheduled ancient monument unless
permission has been obtained from the Historic Buildings and Ancient Monument
Commission for England or the Secretary of State for the Environment in Scotland and
Wales.
It is forbidden to use a metal detector in order to carry out excavations of monuments and
objects, which may relate to prehistory, history, art and archaeology without prior
administrative authorization issued in terms of the qualifications of the applicant and the
nature and modalities of the excavators.
