The depth of detection varies depending on the model and the type of metal being detected. Generally, most metal detectors can detect objects at a depth of 6-12 inches underground.
A metal detector’s detection range varies with technology, ground conditions, and target characteristics. Standard units typically sense small metallic objects a few inches below soil, while professional-grade detectors can identify larger buried metals at significantly greater depths under favorable conditions.
Detection depth depends on factors like coil size, soil composition, and object size. Advanced models can locate large metal items up to 3 feet deep, while smaller targets such as coins are usually detected within 8–15 inches of the surface.
