Hi Jim and Keith, It's a few years since I was detecting in Berlin which at that time was under the control of the BMG - Berlin Military Government (British Sector). Obviously the rules and regulatory controls regarding metal detecting activities will have changed so if you have any news on the current requirements for detecting in Germany, I'm sure there will be interested parties on this forum who would welcome such a 'heads-up'. It's worth mentioning that in my experience, it was common to find both live and expended ordnance in abundance so with safety at the forefront, I was ever mindful that
any targets could be potentially dangerous, so take care! Good Luck in your searches
