It’s impossible to predict with complete certainty how deep a specific detector can be expected to find metal. This is because there are a variety of factors that affect a detector’s performance. For example, the amount of minerals in the soil, the type of metal that’s being detected and the quality of the detector itself impact how deep your detector will hunt. The size and surface area of a target also affects detection. For example, the larger a metal target, the easier and more deeply it can be detected. Using a searchcoil larger in diameter can also help a detector achieve greater depth. A 12.5″ searchcoil produces a more extensive magnetic field that penetrates the ground more deeply to find objects at depths that a smaller size searchcoil can’t reach.
