Feature: 1. [HIGH SENSITIVITY] With high sensitivity and stability, the detector can identify different types of metals and can easily find metal objects that are useful to you. 2. [FAST SCANNING] The detector uses a microelectronic processor to control the chip unit calibration and instrument self checking system, which can scan and test easily and quickly, improve the work efficiency of treasure hunters and reduce labor time. 3. [ACCURATE LOCATION] Metal detectors can identify specific types of metals through frequency modulators, have a remote search system and a precise location detection system to determine exactly where objects are buried and locate them. 4. [DETECTABLE OBJECTS] This metal detector can detect gold, silver, copper, emerald, conventional precious metals, etc. 5. [WIDE APPLICATION] In addition to military applications, detectors are also widely used in security inspections, archaeological treasure exploration, and prospecting.
