CORS Strike Search Coil for Fisher F70 and F75 Metal Detectors The Search Coil used by Professionals and Serious Detectorists! The CORS Strike Search Coil is especially suited to search land heavily littered with iron, such as cities, beaches and parks. Working with a slow swing will help maximize its ability to find not only large and medium targets but small targets which weigh less than 1g as well. This coil is unusually light for its size, which makes it easy to search for a whole day. The coil is superior to a standard coil in depth by 18%-40% (depending on the model of the metal detector) and in ground coverage of between 25%-50% (depending on the model of the metal detector). The CORS Strike Search Coil is recommended as a replacement for standard coils. The coil is fully submersible, the coil body is filled with high quality epoxy resin.
