Advanced Technical Architecture Driving Performance

While the device integrates 15 sophisticated detection systems, its true capability comes from the unified scientific framework that powers them:

Long-Range Detection Platform – Utilizes advanced frequency signal processing to scan expansive areas and track high-value targets over extended distances.

Ground Imaging Platform – Performs multi-layer soil scanning with 3D visualization, allowing detailed interpretation of underground structures before excavation.

EFM Platform – Advanced Audio Detection Technology – Dedicated to precise signal interpretation, metal classification, graphical feedback, and rapid target identification.

Geophysical Platform – Operates by analyzing soil characteristics and electrical resistivity to accurately detect groundwater, metals, and underground cavities.

 

 

15 Detection Systems

The Primero MD15 metal and gold detector integrates fifteen advanced detection systems within a single platform, creating a powerful and versatile multi-system device. This smart integration expands search possibilities while simplifying operation, allowing users to locate their desired targets more efficiently and with greater speed.

 

2. Manual Long-Range Detection System

This system provides complete manual control over the search process, making it ideal for experienced users who require precise configuration. Operators can individually adjust the target metal type (such as gold, silver, copper, or iron), define the desired detection depth, and set the forward scanning distance.

Once the parameters are configured, the device begins transmitting and receiving signals while the user scans the area. The system guides the operator through signal indications that become progressively stronger and more focused as the target location is approached, ensuring accurate directional tracking and precise pinpointing.

• Full customization of search parameters

• Designed for professional prospectors

• Accurate directional guidance and target localization

 

3. Ionic Long-Range Detection System

The Ionic Long-Range System is a specialized technology designed to locate buried metals and ancient treasures by analyzing                                                                                                                                    the ionic fields naturally formed around metallic targets over long periods of time. This advanced approach allows reliable detection of valuable objects that have remained underground for many years.

Key Capabilities:

• Detection depth reaching up to 20 meters

• Forward search range up to 200 meters

• Highly effective in locating gold, silver, bronze, platinum, and copper

• High sensitivity enables accurate detection of both small and large metal targets
