Abstract In a comment on two recent articles on the archaeological impacts of metal detecting, this paper advocates clearer and more valid measures of those impacts and more nuanced classification of the legal and cultural environments in which metal detecting takes place. The need to rely on open-source, online data for transnational analysis makes the former challenging but not impossible. Using the example of Canada, the paper shows that jurisdictional and other complexities make simple “permissive” and “restrictive/prohibitive” dichotomies unhelpful, and suggests using multivariate analysis that accounts for such factors as presumption of ownership, locations of metal detecting, availability of finds reporting, and whether heritage legislation concerns artifacts or only sites. This is essential for development of sound, evidence-based policy on the metal-detecting hobby.

金属探测的考古影响

摘要在对最近有关金属探测的考古影响的两篇文章的评论中，本文主张对这些影响进行更清晰，更有效的测量，并提倡对发生金属探测的法律和文化环境进行更细致的分类。依靠开源在线数据进行跨国分析的需求使前者具有挑战性，但并非不可能。本文以加拿大为例，说明管辖权和其他复杂性使简单的“允许”和“限制/禁止”二分法无济于事，并建议使用多变量分析来说明所有权假设，金属探测地点，查找报告，以及遗产立法是否只关注文物还是仅涉及遗址。这对于声音的发展至关重要，
