[QUOTE="Hawkear, post: 640087, member: 4728"] Even when you are in a known goldfield one of learned skills is being able to "read the ground". Gold is usually in motion both laterally, moving from its primary (or secondary) source and vertically, sinking below surface level under gravity or by alluvium build up. The first part of reading the ground is to have an educated guess as to where the gold in a run of diggings came from and imagine the gold moving between that source and into the gully over time. That would suggest an area to detect. The second part is to consider the vertical issue. At a guess I think a smallish coil seeking out smallish nuggets in ground over 12 inches deep (maybe even less) would be unsuccessful. So you would need to imagine the deepening soil profile from hillside to the gully and imagine where that soil profile would be 12 inches or less. If in doubt even consider deepening one of your holes to the end of the soil horizon to be sure. These two considerations should narrow you search areas considerably and potentially save a lot of wasted time. If you want to go deeper looking for bigger nuggets then bigger coils should be considered but then remember that the number of nuggets diminishes rapidly in an inverse multiple ratio according to their size.
