GREAT King 4S Metal Detector

Depth: 25 meters.

The world’s first device with the latest technology, offering detailed guidance for use with four research systems to detect gold and buried treasures.

Systems

  • System 1: 3D Ground Survey System
  • System 2: Metal Discrimination System
  • System 3: Direct Horizontal Imaging System
  • System 4: Direct Vertical Imaging System

3D Ground Scan

Uses advanced technology to send and receive signals, drawing a 3D diagram of underground objects via a 3D analyzer.

Discrimination

Determines if the target is valuable by analyzing pulses received from the device sensor, recommended before excavation to confirm value.

Vertical Live Scan

Displays frequency changes with graded colors indicating metal presence in a straight line in front of the sensor, using pin pointer system technology.

Horizontal Live Scan

Allows scanning at any angle, ideal for mountain or cave walls using horizontal live streaming technology.

Package Includes

  • GRT King 4S Device
  • Tablet Holder
  • OTG Cable
  • Android Tablet
  • 2 years warranty

Professional Detection Technology

Detects long-buried metals using bio-energy interaction, ionization, electromagnetic detection, microprocessor analysis, and sensor fusion. Longer burial time enhances detection ease.

Practical Testing Methods

  • Field Testing: Historic sites with known buried metals (with permission).
  • Using Known Buried Objects: Test in areas with documented long-buried metals.
  • Avoid Air Testing: Not suitable for freshly buried metals.
  • Avoid Indoor Testing: Electrical systems may interfere with performance.
