The depth at which a metal detector can detect gold depends on various factors, including the type of metal detector, the size and shape of the gold object, and the surrounding soil or material. In general, metal detectors are more effective at detecting larger and more massive objects at greater depths.
For small gold nuggets or flakes, the depth of detection is usually limited compared to larger gold items. High-frequency metal detectors are often more sensitive to smaller targets like gold, but their depth capabilities may be reduced compared to lower frequency detectors.
On average, a decent metal detector may detect a coin-sized or small gold nugget at depths ranging from a few inches to a foot or more. However, these figures are approximate and can vary based on the specific conditions of the soil, the mineralization of the ground, and the quality and settings of the metal detector.
It’s important to note that depth capabilities mentioned by manufacturers are often based on ideal conditions and larger target sizes. Real-world performance may vary, and factors like ground mineralization and the presence of other metals can impact the actual depth at which a metal detector can detect gold.
