NJ A1930. If you are metal detecting in New Jersey, you may now be breaking the law! The state legislature recently passed A1930 and I seriouly suggest you read it carefully. Start contacting your local towns and find the name of the person authorized to grant or deny permission to detect. I would like to start building a database of goverment contacts if we can't get this stupid law amended. I am hoping we can get the law amended as it is very broad in scope and vague. First time penalties start at $750 and could include confiscation of equipment and vehicles used!
