degree of mineralization of soil. For example, in order to understand how strong is the signal
from the soil on a definite location, one can lift the searching coil in the air and the device to be
nullified with short pressing of
"ON – OFF / CLEAR".
Then, the coil is brought close to the
ground surface and one can se opposite „
Level“
what is the indication of the signal of the soil.
Upon a signal from the soil of up to „
Level: 20“
one can operate in
"NORMAL DISCR"
mode,
but at higher levels of mineralization one has to switch to
"auto discr" or "AUTO DISCR",
which
features are explained below.
Searching metal objects is made by moving search coil toward ground surface – fig.1 , fig.2

The search coil should not touch the ground during your sweep. The pole length should be
adjusted to allow this without having to lift the detector with your elbow or shoulder. The search
coil should rest about one inch above the ground while you are standing erect. The angle of the
search coil should allow the bottom to be parallel to the ground.
2.1 Setting of working parameters in "VCO" mode
setting of the threshold of co – working of the sound
"Thresh" –
this is the level of signal after
passing of which a sound is heard. The device may be set at such strength of signal to react with
