DD coils like the LD22 maintain stable operation in mineralized soils, wet sand, and saltwater beaches where concentric coils often chatter or produce false signals. The DD configuration provides excellent ground balance in mineralized soils that can cause concentric coils to struggle. If you hunt relic sites with aggressive iron mineralization or coastal areas with wet sand, the DD design gives you smoother performance and fewer false signals. You can learn more about metal detector technologies and how coil geometry affects performance.
