Product Description
This professional 32-channel Magnetometer Metal Detector is jointly developed with the Hydrogeology Survey Institute of Guilin University of Technology. The system measures natural low-frequency electromagnetic signals to map resistivity variations, identify mineralized zones, locate groundwater, and reveal buried structures.
By collecting all channels simultaneously, the instrument ensures a stable field source and eliminates errors associated with repeated electrode movement. Each survey line is completed in a single pass, producing consistent imaging results for reliable geological interpretation.

Advantages
• Consistent Profiles
Simultaneous channel acquisition eliminates mismatched sections and maintains stable field conditions.
• Strong Low-Frequency Response
Captures weak natural signals while reducing interference from source-field variations.
• Efficient Single-Pass Surveying
Each profile requires only one run, improving productivity in mineral and water prospecting.
• Suitable for Remote Terrain
Optional wireless EM probes reduce wiring and enhance mobility in rugged areas.
• Integrated Ecosystem
Works smoothly with mobile apps, cloud tools, and intelligent analysis software.

Customer Benefits
Using the 32-channel Magnetometer Metal Detector from Rancheng Machinery gives customers clearer subsurface insight, faster decision-making, and more confidence in exploration planning. The stable multi-channel acquisition provides consistent profiles, helping reduce the uncertainty often associated with mineral or groundwater prospecting. Real-time imaging shortens fieldwork time and allows teams to identify drilling targets or geological risks directly on site. The system's efficient workflow minimizes labor, wiring, and repeated measurements, creating a smoother survey process from data collection to interpretation. With reliable structural mapping and streamlined data transfer between instrument, mobile devices, and computers, customers can evaluate resources more accurately, improve project efficiency, and lower overall exploration and engineering risks.

How to Use the Magnetometer Metal Detector?
Line Installation
Insert electrodes, clip the survey cable, and connect the line to the main unit.
01
Instrument Setup
Open the app → choose "Serial Connection" → configure channel count, measurement mode, and depth.
02
Create Project
Set project name, line number, and line spacing.
03
Start Measurement
Automatic channel diagnostics:
• Blue = channel OK
• Red = channel error
Once confirmed, begin acquisition to collect the complete profile.
04
Auto-Imaging
Generate 2D profiles onsite. After multiple lines, create 3D and slice-view models for real-time geological interpretation.
