Go to Beach with
Choose YES (00-30), with
Activates calculation of the ground balance on the zone corresponding to
highly saline wet ground, so as to reduce interference caused by conductive
salt water. After selecting Beach ON, you need to adjust the ground balance
manually or by pumping on the wet zone concerned, in order to cancel out
the ground signal.
Go to or with
Press and pump the coil on the ground several times until you obtain
the display "
GB OK ".
In Manual Mode, adjust it from 00 to 30 with . Exit with
To improve stability on wet beach (salt water):
Reduce Audio Response (0-1) / Increase Reactivity (4)
Power: Level 1 maximum. / Sensitivity: (70-85).
In wet zones (salt water), it is important to sweep while keeping the
coil parallel to the ground, yet not touching it.
In wet zones select the Wet Beach factory programme.
If you see the G.B FAIL screen. It is possible that the soil is irregular or
not mineralised. Adjust the ground balance from 25 manually.
This mode is not available in Beach mode, as the Pumping mode is more effective.

GROUND
However, in ground where mineralisation is a result of human presence (ancient settlements, for
example) this mode may be unsuitable due to ever changing ground conditions. Indeed, within the
same sweep of just one meter, a considerable variety of ground conditions may be encountered,
ranging from one extreme to the other (values between 70 and 90): hot rocks, brick, slag, pottery
interspersed with soil that is neutral or characterised by diverse mineralisation. This may be to such an
extent that any mean value would be meaningless. You must then determine an acceptable level of
rejection for the ground based on your own experience of the site, your detection methods and the
interference that you are prepared to tolerate.
In this mode, the Dēus repeatedly scans the ground and digitally filters the
extracted signals to determine the mean value on a continual basis. This mode
may be useful in soils with relatively uniform mineralisation, and where the
mineralisation varies gradually from zone to zone, which is often the case in
naturally mineralised ground. In this case, the Dēus automatically readjusts the
ground balance according to the most recent value measured.
Low ground balance levels also generate the clearest signals on certain irons targets that are
already difficult to eliminate.
