The GR26’s DD (Double-D) configuration is engineered to reduce ground mineralization interference compared to standard concentric designs. In highly mineralized gold fields, the DD footprint helps maintain stable ground balancing and minimizes false signals or "chatter." This makes it significantly easier to isolate real targets in difficult, hot soil matrices. For more on how coil configurations affect performance, see our guide to metal detector technologies.
