If not you are quite clearly digging illegally and will be subject to the full force of the law if caught plus we do not tolerate or condone illegal digging on this forum !!
As this member has not responded to clarify his activities i am assuming he is breaking the law and digging illegally so a ban is in order.
As Paul D already stated it is illegal to dig in the public area's and State owned forests in the ardennes but it does apply for the whole country of Belgium, digging is only permitted on privat land with a written and signed consent of the owner. You have to know that you can only dig as deep as 1Ft or plough depth. The rules are actually changing and so is the law. As it stands soon you will need a permit to MD in historic relevant area's(WW1 & WW2 battlefields included) when digging for such artefacts, even on privat owned land.
