be restricted by some factors:
l
The angle of the target buried in the soil.
l
The depth of the target.
l
The level of oxidization of the target.
l
The size of the target.
l
Electro-magnetic and electrical interference surrounding the target.
In area of highly mineralized ground, or fertile ground, or wet sand, the detector
will sound even if there is no metal. In this case, you can lower the sensitivity.
Meantime enhance the distance between the search coil and the ground.
Metallic digging tools will also affect the detection if they are near the search
coil. So it’s better place them a little far away.
