The depth that a metal detector can detect a target depends on a number of factors:
Large targets can be detected deeper than small targets.
Circular shapes like coins and rings can be detected deeper than long thin shapes like nails.
A horizontal coin (e.g. lying flat) can be detected deeper than a vertical coin (e.g. on edge).
High conductive metals (e.g. silver) can be detected deeper than low conductive metals (e.g. lead).
Another factor is the size of the search coil. Search coils come in a wide range of sizes and shapes, including 4″, 6″, 8″, 9.5″, 12″ and 15″. There are also differences in the configuration of the coils inside the search coil producing different shape search patterns. The larger the search coil, the deeper it can detect larger metal items. However, it is more difficult to use in trashy areas with less depth to find small metal items. Smaller search coils provide better separation in high-trash environments and better sensitivity to small metals.
