Metal Detector Sensor ( Pentangeli version )
This is a pulse induction metal detector made in Egypt . It uses a single search coil .
It can detect metal objects under ground, through wall and above ground as well. Typical minimum depth range from 25 to 30 cm underground. This range is obtained with very rough quick made coil (not optimized) using 10 cm diameter object.
The metal object detection is indicated by LED. Recommended voltage supply is 14 V with small current. However the Metal detector was extensively tested and found to be stable operation in range of voltage supply (12 : 16 V)
