The long-range gold detector Bionic X4 is especially made to detect underground gold treasure. So it’s not surprising, that one of OKM’s customers found a hoard of gold and silver coins near to Shiraz.
The located hoard consists of many gold dirhams as well as some silver dirhams. The dirham is an Arabic unit of weight and coin value. Since dirhams as currency were not used before the 7th century, you may assume that this gold treasure is not from ages before common era. The deep treasure has been found by processing a cross-bearing with Bionic X4. The procedure is to scan from several directions (at least two) and find the intersection point. The gold and silver coins has been detected in a depth of 1.10 meters (3.6 feet).
