Frequently Asked Questions (FAQ)

Welcome to our FAQ page! Here is a list of frequently asked questions about various aspects of metal detectors and their use. We would also like to give you an overview of the different types of detectors used in metal detectors and ground scanners. We also address the issue of counterfeit products on the market to educate and protect you as a consumer.

1. Detector types 

There are different types of metal detectors including VLF detectors and professional grade pulse induction (PI) detectors. VLF detectors are suitable for searching for metallic objects at shallow depths, such as searching on the beach or "treasure hunting" with children. PI detectors, on the other hand, are better suited to detecting deeper gold deposits and larger metallic objects. 

1.1. VLF (Very Low Frequency) detectors

How it works: VLF detectors work with low frequencies that are sent into the ground. Metallic objects affect these frequencies and create a signal in the detector. The device analyzes the signal changes and thereby detects the presence of metals. 

Areas of application: VLF detectors are suitable for finding everyday metallic objects such as coins and jewellery. They are effective in less mineralized soils and are often used by beginners and hobbyists. 

1.2. Pulse Induction Detectors (PI) 

How it works: Pulse induction detectors generate short, intense electromagnetic pulses. These pulses create a magnetic field in the ground that is disturbed by metal objects. The detector recognizes the changes in the magnetic field and thus identifies metals. 

Areas of application: Pulse induction detectors are ideal for searching for deep-lying metallic objects. They are efficient in heavily mineralized soils and are well suited for treasure hunting in demanding environments. 

1.3. GPA Groundscanner (Ground Penetrating Analyzer)

How it works: GPA ground scanners use a special probe that receives electromagnetic signals that are naturally emitted by the environment. These signals are influenced by underground structures and objects and are picked up by sensors in the probe. By analyzing these received signals, the GPA creates images of the ground structures. 

Benefits of the GPA:  

• Depth Detection: GPA enables the detection of deep objects, such as treasure or structures, that other detectors miss.  
• Accuracy: Thanks to its ability to create detailed images, users can get more precise information about the type and location of objects underground.  
• Versatility: GPA is used in professional gold prospecting, finding gold deposits, treasure hunting, archeology and structural investigations. It offers wide application possibilities for different areas.  
• Minimal Interference: The technology minimizes interference from surrounding materials and enables accurate data to be collected.
