Magnetron Geoscanner Basic V2 – Portable Magnetic

One of the main advantages of the Magnetron Geoscanner Basic V2 is its ability to generate magnetic heatmaps directly on the integrated display.

Unlike traditional magnetic survey tools that require transferring raw data to a computer before visualization, the user can see magnetic variations immediately during field scanning.

The system supports adjustable scan grids from 4×4 to 7×7, allowing both quick surveys and more detailed magnetic mapping.

After scanning is completed, measurement data can be saved to a microSD card as CSV files and analyzed further using the custom Magnetron PC Suite software.

The PC software provides advanced visualization tools including:

• Smooth heatmap generation
• Cubic and linear interpolation
• Multiple color maps
• Iso-line contour visualization
• Single and multi-scan comparison
• PNG image export

This combination allows users to move from field measurement to detailed desktop analysis with a simple workflow.

The Magnetron Geoscanner Basic V2 hardware architecture is designed around a dual magnetic sensor configuration, allowing differential magnetic field measurement and improved anomaly visualization.

The system uses two high-sensitivity analog fluxgate magnetic sensors connected to a 16-bit ADS1115 ADC module. Compared with the previous generation, the high-resolution ADC provides better measurement stability, reduced noise, and improved sensitivity.

An Arduino Nano handles sensor acquisition, calibration routines, and communication with the user interface.

The visual interface is powered by an ESP32-S3 touchscreen display, providing a standalone portable operating experience without requiring a computer during scanning.

Main hardware components:

• Dual fluxgate magnetic sensors
• ADS1115 16-bit high-resolution ADC
• Arduino Nano controller
• ESP32-S3 4.3" touchscreen HMI
• MicroSD data storage
• Li-ion battery power system
• DC-DC power regulation and battery monitoring

The complete electronic architecture combines compact size, low power consumption, and high measurement accuracy for portable magnetic field surveys.

Magnetron Geoscanner Basic V2 is a portable magnetic field imaging system developed for geophysical exploration, education, research, and experimental magnetic surveys.

The system combines dual high-sensitivity fluxgate magnetometers, a 16-bit ADS1115 analog-to-digital converter, Arduino Nano control electronics, and an ESP32-S3 touchscreen interface.

Unlike conventional magnetic survey instruments that require post-processing on a computer, Magnetron Basic V2 generates real-time magnetic heatmaps directly on its integrated display.

The user can scan an area using adjustable measurement grids, instantly visualize magnetic anomalies, and store measurement data on a microSD card. The collected data can later be analyzed using the custom Magnetron PC Suite software.
