you to identify search objects at a greater depth. It has the value from 1
to 14. Remember that with an increase in the identification sensitivity of
the device, not only the search depth increases, but the possibility of
the appearance of inter-
ference from power lines
and from false alarms
from differences in min-
eralization of the soil, as
well as when the coil hits
the objects.

device. The threshold tone is a signal from the detection channel that
Fig. 6 gives you information that the device has detected a metal object.
From the moment of detection and along the movement of the coil,
the volume of the threshold tone rises, having the highest value above
the center of the target. With a gain of experience working with the
device, a combination of the threshold tone and the tone of the identi-
fication signal, as well as the duration and volume level of the threshold
will be able to give you more complete information about the size and
relative depth of the target, and even about the presence of two targets
with a single identification signal. In most cases, we recommend setting
the value to 6-7.
Some recommendations for the sensitivity of the device:
Select the optimal sensitivity at the search location, based on the rule
"the highest value possible for stable operation of the device in this place".
It is also recommended to reduce the sensitivity of the device in plac-
es heavily littered with metal. Due to the strong emitting from a large
amount of surface iron, the device is unlikely to be able to detect at max-
imum sensitivity a useful target located deeper than this iron, despite
