The ADMT series of geophysical detection instruments, utilizing the Natural Electromagnetic Field (MT) method, accurately images subsurface structures by measuring resistivity variations. This product line offers comprehensive solutions from shallow (20m) to ultra-deep (5000m) exploration, including the ADMT-20KG-X, 60KG, 100KG single-channel models and the advanced multi-channel ADMT-AX series. These instruments demonstrate core advantages of high precision, efficiency, and adaptability in karst cave detection, archaeological prospecting, and oil & mineral exploration.

The Evolution of Subsurface Imaging

In an era demanding non-invasive and precise subsurface investigation, intelligent geophysical technologies are crucial for engineering safety, archaeological discovery, and resource exploration. Moving beyond costly and disruptive traditional drilling, instruments based on the Magnetotelluric (MT) method represent a significant leap. The ADMT series analyzes variations in the Earth's natural electromagnetic field to map subsurface resistivity, enabling rapid identification and 3D visualization of cavities, geological structures, and mineral deposits.

ADMT-20KG-X: The Portable Solution for Shallow Surveys

The ADMT-20KG-X is an entry-level professional instrument designed for high-resolution cavity detection. Its key strengths are portability and ease of use. Featuring a 7-inch IPS touchscreen running Android 6.0.1, it offers three selectable detection depths (5m, 10m, 20m) within a 100Hz-8kHz frequency range. Using either MN electrodes or TT electromagnetic probes, it generates 2D/3D resistivity profiles and curves on-site. Data syncs seamlessly via serial port, WiFi, Bluetooth 4.0, or USB to mobile devices and the cloud.

In practice, its lightweight design (1.6kg host) and detachable battery enable solo field operations, making it ideal for urban road collapse risk assessment, small-scale karst surveys, and preliminary archaeological site scanning. Its "field source stabilization" technology mitigates interference from natural field strength fluctuations, ensuring data stability with a repeatability error within ±2%.

Expanded Product Matrix: Full-Depth Coverage from 60KG to AX Series

To meet diverse depth and precision needs, AIDU offers a complete product portfolio. The ADMT-60KG extends depth to 60 meters, with a 16-channel version (ADMT-60KG-16D) available for efficient profile measurement. The ADMT-100KG pushes depth to 100 meters with 0.001mV resolution, excelling in dam seepage detection and deep cave surveys.

For professional resource exploration, the ADMT-AX series represents the technological frontier. The ADMT-200AX, designed for mineral exploration, reaches 500 meters depth using multi-physics coupling technology. The ADMT-300AX-32D, with a 32-channel system and 0.01Hz-10kHz ultra-wideband frequency, achieves 300-meter depth with a 92% detection rate for small targets. The flagship ADMT-5000AX utilizes Controlled Source Electromagnetic (CSEM) technology for ultra-deep exploration up to 5000 meters, targeting national-level deep-earth resource and geothermal projects.

Application-Specific Advantages

Karst & Geohazard Detection:​ In karst regions, the ADMT series accurately locates underground cavities, goafs, and subsidence zones via resistivity anomalies. The ADMT-60KG successfully identified karst caves ≥0.3m in diameter in a Yunnan mining area. For landslide analysis, the multi-parameter inversion of the AX series reduces interpretation ambiguity.

Archaeology & Cultural Heritage:​ The ADMT-60K 3D imaging archaeological void detector identifies magnetic anomalies from tombs, walls, and artifacts. At a Henan site, it scanned a 100m² area in 5 minutes, generating immediate 3D maps of burial distribution, dramatically improving survey efficiency.

Oil, Gas & Mineral Exploration:​ Deep penetration and multi-parameter analysis are critical here. The ADMT-500AX-16D uses ultra-wideband technology to map ore bodies or hydrocarbon reservoirs at 50-500m depths, with a 90% detection rate for small targets. The ADMT-5000AX breaks depth barriers, having successfully mapped oil-bearing structures over 3000m deep beneath thick conglomerates in the Tarim Basin.

SUNGOOD TECH: Integrated Provider for the Drilling Sector

As a specialized drilling equipment manufacturer and the authorized distributor for AIDU detectors, SUNGOOD TECH provides an end-to-end service from geophysical survey to drilling execution. The company supplies the full ADMT detector range alongside complementary equipment like core drills, directional drill pipes, and tooling. This integrated model ensures unified technical standards, seamless data integration, and coordinated after-sales service.

In practice, SUNGOOD TECH first uses ADMT instruments for precise target , then matches the optimal drilling rig based on the results. For instance, a deep-hole rig and high-temperature tools are provided for a 300m geothermal reservoir identified by an ADMT-300AX, while a lightweight backpack drill is used for verification at shallow archaeological sites. This "detect-to-drill" solution significantly reduces project costs and improves exploration success rates.

The Future of Intelligent Detection

The ADMT series, with its comprehensive product matrix, enables full-scenario geological exploration. Its core value lies in transforming complex geophysical data into intuitive visuals, making subsurface interpretation accessible. With further integration of AI and IoT, future detection will trend toward greater automation and interpretive power.

For end-users, selecting the right instrument depends on required depth, precision, and operating environment. The portable ADMT-20KG-X suits rapid surveys; the 60KG and 100KG models meet most needs; the AX series serves professional resource exploration. Partnering with an integrated provider like SUNGOOD TECH ensures access to advanced technology alongside a complete workflow solution, maximizing both operational efficiency and economic return.
