Metal Detecting in Bulgaria
In Bulgaria, archaeological field surveys require authorisation, and equipment used for archaeological searches is subject to registration with the Ministry of Culture. Registering a detector is not the same as receiving permission to search for archaeological objects. The official application process concerns qualified archaeological work rather than a general tourist hobby permit. I could not verify a blanket permission covering searches for modern lost items, so I would ask the Ministry about the exact activity and location before searching.
Detector Lady recommends: Before travelling with your metal detector, always check the country’s current rules and the conditions for the exact place you want to search.
