Sensitivity High sensitivity to small targets High sensitivity with deep penetration
Discrimination Effective discrimination between different metals Less accurate discrimination
Ground Conditions Low mineralization, less electromagnetic interference High mineralization, volcanic rocks
Price Range Affordable Expensive

As seen in the table, VLF metal detectors are suitable for less mineralized areas and offer better discrimination capabilities. On the other hand, PI metal detectors are more adept at handling highly mineralized ground conditions while providing deeper detection depth. The choice between VLF and PI metal detectors depends on your prospecting goals, the ground conditions you encounter, and your budget.

How Do Frequencies Work in VLF Metal Detectors?

VLF metal detectors utilize a range of frequencies to detect different types of targets during metal detecting. Understanding how these frequencies work can help you optimize your settings and improve your chances of finding gold.

Higher frequencies are particularly effective at detecting smaller targets that are closer to the surface. These frequencies allow the detector to accurately pinpoint tiny gold nuggets or other valuable objects that might otherwise go unnoticed. If you are searching in areas with minimal ground mineralization and hope to unearth small treasures, a higher frequency setting will be advantageous.

On the other hand, lower frequencies are better suited for searching deeper into the ground and detecting larger, more conductive targets. These frequencies can penetrate through layers of soil and mineralization, giving you a better chance of discovering bigger gold deposits or valuable artifacts buried at greater depths. If you are exploring areas with significant ground mineralization or targeting larger gold nuggets, using a lower frequency setting is recommended.

It’s important to note that the frequency you choose should also align with the size of your coil. Larger coils are more suited for lower frequency settings as they provide better depth penetration, while smaller coils are ideal for higher frequency settings as they offer enhanced sensitivity for fine detection.

By understanding the relationship between frequencies, target size, and ground conditions, you can fine-tune your VLF metal detector to optimize its performance and increase your chances of uncovering gold treasures.
