Metallo-Find

"If it is made of metal, Mettalo-Find will know it"

- National Geographer Magazine

Metallo-Find was a metal detector designed exclusively for entertainment purposes. The DeLux model of the device with radio controls and patented voltmeter was advertised in the classifieds section of National Geographer Magazine in 1935 where it was promoted as finding any metal up to a depth of 25-feet, though use underwater was discouraged.
