The INV40 coil is compatible exclusively with the Nokta Invenio metal detector. This 15.5" x 14" DD coil is engineered specifically for the Invenio's electronics and mounting system, and it will not fit other Nokta models or detectors from other manufacturers. The mounting hardware included with the INV40 ensures a secure fit on the Invenio's lower shaft, providing the proper alignment and stability needed for effective detecting. The coil's DD configuration works seamlessly with the Invenio's detection capabilities to deliver excellent depth and target separation in various hunting conditions. If you own a different Nokta detector model, check our full range of metal detector search coils for compatible options.
