The modern progress from the metal detector started in the twenties. Gerhard Fischer had designed a method of radio course-discovering, which was for use for precise navigation. The system worked particularly very well, but Fischer noticed there were anomalies in regions wherever the terrain contained ore-bearing rocks. He reasoned that if a radio beam could be distorted by metal, then it should be feasible to style a machine which would detect metal employing a search coil resonating in a radio frequency. In 1925 he metaldetector applied for, and was granted, the 1st patent for an Digital metal detector.
