🧭 Use Applications

The Ajax Detection Primero is purpose-built for professional-grade exploration. Each detection system is optimized for a specific use case, allowing field operators to adapt to changing terrain, target types, and soil conditions with unmatched precision.

Gold & Precious Metal Prospecting: Utilize the Long-Range Locator and Ionic systems to scan for buried gold veins, ancient coin hoards, and non-ferrous metallic targets up to 50 meters deep. Fine-tune the search frequency based on the mineral composition of the area.

Archaeological Excavation: The 3D Ground Imaging and Magnetometer systems provide spatial awareness of buried ruins, walls, tunnels, and artifacts without disturbing the site. Ideal for historical surveys and pre-dig scans in sensitive zones.

Geological & Mineral Exploration: Use the Geophysical Survey system to detect natural mineral deposits and voids. The system distinguishes between conductive materials and geological formations using advanced pulse signals.

Subsurface Structure Mapping: The Live Scan and Bionic systems allow users to walk an area while generating real-time data on buried objects, cavities, or irregularities. Great for identifying structural anomalies before construction or excavation.

Void & Cavity Detection: Use the Smart Detection and Ionic scan modes to locate underground chambers, tombs, cellars, or caves. These systems highlight differences in soil density and electrical conductivity for high-resolution interpretation.

Law Enforcement & Security Investigations: Identify buried weapons caches, smuggling tunnels, or contraband containers in remote or high-risk areas using a combination of scanning modes and GPS-tracked logging.

🧭 Explorer Tip

When using the 3D Ground Imaging system, always perform a manual ground balance on the scanning area before starting a multi-point survey. This step is crucial in mineral-rich environments where false positives can easily occur. Walk the perimeter first using the Live Scan or Magnetometer to rule out shallow ferrous debris — then conduct your full sweep in grid passes. For cavity detection, lower the sensitivity slightly to avoid signal distortion from air pockets or water seepage. Lastly, always log GPS coordinates with each scan — it’ll save hours when revisiting target sites later for excavation.

🧭 Field Report

Location: Southeastern Turkey – archaeological zone near Mardin

Conditions: Volcanic rock layer, mineral-rich soil, ambient temperature 34°C (93°F)

Objective: Identify subsurface voids and trace metallic anomalies within a historical dig corridor

The Ajax Detection Primero 3D was deployed over a 6-day survey supporting an active archaeological team. Using the 3D Ground Imaging system, we performed layered sweeps of a 50 x 50 meter grid. The device produced high-contrast color scans showing cavity formations that corresponded with old chamber walls beneath the surface — later confirmed by ground-penetrating radar and partial excavation.

The Magnetometer system proved effective for identifying iron artifact clusters at depths between 1.5–2 meters, allowing the team to flag high-potential zones before breaking ground. We used the Ionic Detection system in parallel to detect oxidized coin deposits in a surrounding field area, where historical trade routes had been previously documented.

What stood out most during this deployment was the Primero's adaptive calibration — it maintained accuracy despite fluctuating soil conductivity and high mineral interference. Battery life was reliable across full workdays, and the control unit UI made switching modes and marking GPS zones quick and repeatable.

Conclusion: The Primero is a genuine multipurpose platform. It’s a serious tool for professional surveyors and researchers who need field flexibility, accuracy, and subsurface visualization in one cohesive system.
