The White's TM 808 metal detector was introduced in 1996 and was still in production when White’s closed up shop in 2020. The TM 808 is a "two-box" metal detector that is designed for finding large objects at depth. Two box detectors are not sensitive to items much smaller than a baseball, but can detect large items like a 55 gallon drum or water main to depths exceeding ten feet. Two box detectors are a favorite of the classic "treasure hunter" but are more often used by utility companies and surveyors. The TM 808 originally included a "Cave Mode" intended to find large underground cavities. This "Cave Mode" was removed about 2010.
"TM 808 is designed for locating coin caches, treasure chests and hordes of gold or silver - as well as septic tanks, tools, equipment, metal pipes and relics." Source: White's 2018 catalog
