Pulse Induction Metal Detector Best For Finding Gold

Pulse Induction Metal Detector Best For Finding Gold

The pulse Induction metal detector is the best metal detector for finding gold in the WA Gold fields because; PI Detectors do not respond to the iron mineralization commonly found in the WA Goldfields e.g. magnetite. This is strongly evident in magnetite hotrock conditions which will cause the VLF to overload but not impact on a PI.
