The method labored particularly perfectly, but Fischer seen there have been anomalies in areas where the terrain contained ore-bearing rocks. He reasoned that if a radio beam might be distorted by metal, then it should be probable to design and style a equipment which might detect metal employing a research coil resonating at a radio frequency. In 1925 he used for, and was granted, the very first patent for an electronic metal detector.

Once I used to be acquainted adequate Together with the detectors, I afterwards did what’s identified as a seeded hunt.
