Features:  1. The detector has high sensitivity and stability, can recognize different types of metals, and can easily find metal objects that are useful to you.  2. You can use metal detectors to explore more places for treasures, looking for gold, silver, copper and precious stones.  3. It will determine exactly where objects are buried and locate them.  4. It can identify specific types of metals through a frequency regulator.  5. It has remote search system and precise location detection system.  6. The use of microelectronic processor to control the chip unit calibration and instrument self-inspection system can facilitate and quickly scan and test, improve the work efficiency of treasure hunters, and reduce the labor intensity of the test.   7. For 5 x 5cm objects, the instrument can detect at least 3.5 meters.Objects of 30 * 30cm can be detected in a range of 5 to 8 meters, and objects of this size can be detected in a range of 20 meters if they have been buried for a long time.If the object is large, the depth will be deeper.
