The GOLD FIELD program uses a different detection strategy designed to handle highly mineralized ground containing targets such as gold nuggets. In these ground conditions, small, low-conductive targets are often seen as ground noise or iron, especially when they are deeply buried. To go deeper in these difficult conditions, the GOLD FIELD program uses a true All Metal mode allowing you to accept a whole zone of ground that is usually rejected (Full Range). Rather than rejecting all the ground values below the setting (as on conventional detectors), this new program rejects only the current value of the ground which you have to adjust exactly.
To simplify this ground effect adjustment (which is essential in this program), the “pinpoint” touch pad allows you to quickly grab the ground value while pumping the coil to the ground. In this program a few settings are not active or are replaced by others unique to the GOLD FIELD program including:
- The IAR discrimination (Iron Amplitude Rejection): Adjustable from 0 to 5, IAR is applied only to strong signals (shallow). This avoids the rejection of signals from good targets further away that may sound like ferrous when they are buried in mineralized ground (pg: 10).
- Immediate sampling of the ground value (Grab) accomplished by simply pressing “Pinpoint” while pumping the coil to the ground. Pinpoint function is deactivated in this program (pg:18/19) Note: The target ID feature is retained when working in the All Metal mode to aid in target identification.
