A few friends and I have plans to do some metal detecting in France, in the fall of this year. Are there any metal detecting forums (even if in the French language), where a person could correspond ahead of time, to find out do's/don'ts/tips, etc...?
You will want to go in Bourgogne region. It is a region where there was a lot of dukes. There is Also a canal there. Follow this waterside and You should find a lot of Stuff. I lived three years in Switzerland and my ex-husband is french. Enjoy!
