Raw gold detectors, There are two types of devices for detecting and prospecting raw gold. The first type is the electromagnetic sound system. This type is suitable for sandy soil and targets with a depth of 1 to 5 meters underground.
The second type is the sensory system devices to detect raw gold with great depths up to 30 meters under the ground which is more suitable for rocky soil and works in sandy soil as well, the sensory system is more accurate in research because the devices contain a program specialized in the detection of raw gold, which makes the device give a signal only for Gold metal without reference to non-precious metals in addition to the possibility of scanning large distances at the horizontal level from the surface of the earth.
