Digital geophysical metal detectors
Digital geophysical metal detectors are used during the Remedial Investigation/Feasibility Study of the Mullet Key Formerly Used Defense Site (FUDS) at Fort DeSoto Park near St. Petersburg, Fla. The technology identifies buried metallic objects; crews then dig a select number of targets to further identify whether the objects are munitions-related or scrap metal. The Corps is complementing this effort for the first time on a FUDS by testing the use of explosive detection dogs that can locate buried explosive materials.
