The different levels of soil mineralisation you encounter when prospecting
can sometimes affect the performance of your detector.
For example, this may be due to natural magnetic mineralisation such as
iron oxide, hot rocks and magnetite, or sporadic mineralisation from sites of
former human settlement (also magnetic): hearths, pottery, hot rocks, slag,
etc. At the seashore this may also involve mineralisation ranging from
magnetic grade (black sand) to electrical conductor grade (salt water)
depending on the beach or region.
If you are an experienced detectorist you may wish to optimise your
searches to achieve better penetration in some of these mineralised soils.
In magnetic ground with relatively uniform mineralisation, a setting
which is adjusted according to the ground effect will improve penetration by
reducing the amplitude of the ground signals sent back by the receiver
circuits. This ‘adapted setting’ involves adjusting your ground balance
value to the average value of the ground being detected, while adding
1 so as not to hear the ground signals as much. The tracking and pumping
modes do this automatically if the ground conditions allow it. With the
Prog.10 Gold Field it is vital to set exactly the value of the ground.
Attention: As the ground balance setting is the one requiring the most
experience, we recommend that you read this chapter and use the
different ground balance modes carefully, while acquiring your own
experience of the ground.
By default, remain in manual mode at level 90 on inland ground and on
dry beach sand. On wet beach reduce the level from 25 to 27.
If the ground is not mineralised (see below the bargraph : Minerali-
sation strength) there is no need to adjust your ground balance to a level
other than 90: since the ground does not send back any significant
spurious echo, the performance will be optimal even at level 90 and you
will reduce interference resulting from knocks to the coil.
On the main menu, two values are permanently displayed:

The ground mineralisation index
(phase measured constantly
for information).
The actual level of ground effect corrections
(phase adjustment underway).

Mineralisation strength
. The higher this value is, the
more mineralized the ground is. Pump the coil up and down
several times to evaluate the mineralisation strength. If the level
is low, there is less of a need to make any adjustments.
