The procedure worked exceptionally nicely, but Fischer discovered there have been anomalies in areas the place the terrain contained ore-bearing rocks. He reasoned that if a radio beam could be distorted by metal, then it should be achievable to style a device which might detect metal employing a look for coil resonating at a radio frequency. In 1925 he applied for, and was granted, the initial patent for an Digital metal detector.
