The GK26C's concentric coil provides precise target pinpointing and cleaner ground balance in mineralized soil compared to DD coils. Concentric geometry focuses the detection field directly under the coil's center, so when you get a signal over a bedrock crack or between rocks, you know exactly where to dig without the edge-to-edge uncertainty a DD coil introduces. DD coils excel at target separation in trashy ground and handle extreme mineralization better, but concentric coils deliver tighter pinpointing when you're working clean bedrock or boulder fields where iron trash is minimal. Gold prospectors hunting exposed bedrock often prefer concentric coils for that centered signal response.
