SMART SENSOR An Underground Metal Detector is an electronic instrument which detects the presence of metal nearby. Underground metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground. They often consist of a sensor probe which can be swept over the ground. Usually the device gives some indication of distance; the closer the metal is, the higher the readings go. The use of this detector can detect is not buried deep mineral deposits, including native gold, gold, gold, and
other various rich sedimentary sand. Detection of natural gold nuggets want to look for the metal coins,
with balance; most gold under a higher degree of mineralization in the rocks, so it must be carefully
adjusted to balance. In the ore, gold with extremely broken forms and blends in with the sands, sediment
and heavy metal ore often has a large number of signals and black metal, caused by the mixture of the
same, but the reaction than the pure metal is relatively weak, and generally sound area relatively wide. 
Features: 1. Apply an electromagnetic field to detect the presence of a concealed metal object.
2. Designed to find gold & silver jewelry, coins and other metal in the ground, and can also find land mines.
3. Adjustable height of metal detector, with ground balance & recognition of explore modes.
4. Lighting and audio indicate the detection of metal.
