Metro Spy Supply is a subsidiary of Metro Private Investigations, Inc ( MPI ); established in Huntsville, Alabama in 1971. Because MPI utilizes a variety of investigative products in the field, it was a natural fit to make these very same products available to investigators and others with security concerns. Our "hands-on" field experience ensures that we provide you with only the best spy products and support to meet any personal or business situations you may encounter. MPI employs several investigators nationwide. Interestingly enough, 70% of these investigators are female. Each investigator brings with them a special expertise, ranging from bilingual language skill sets, to special training in forensic sciences, or accident reconstruction.
