Every job needs a proper tool... and every detecting condition is different. Sometimes the change of a coil can bring new life to an otherwise unproductive site. Small coils are great in trashy areas, but at a loss of some depth. Larger coils detect items much deeper than a stock coil, but may not be able to find small targets in the vicinity of undesireable ones. We offer a large selection of coils to fit your detector and suit your needs.
