constant adjusting and therefore, it is not intended for a lengthy search.
To switch the appliance from the basic search mode to static mode (Pin-
point)
Click In the right-hand side of the Scr
een there will appear the
letter “C”, and on the left the value of the gain for
the static mode along with the ability to change this

(fig. 11)
(fig. 11)
The gain of the static mode is
selected experimentally de
pending on the specific
conditions. The choice of this
parameter will depend on the
relief of the ground, littered
area, temperature changes, etc.
As already mentioned, the
active mode (pinpoint) is used
to determine the
e
xact
location of the object. Let us
give some practical tips on
how to
u
se this mode.
After locating an object, in the
static mode, and deciding it is
worth digging it is time to de
fine its exact location. To do
this, move the search coil off
of the approximate center of the target either left or right (line A see
Figure 12).
Then turn on the static mode (Pinpoint).
As accurately as possible, while maintaining the distance between the
ground and the coil
, scan the object backwards. Determine on line A the
location (coordinate) where the tone of the sound was the highest.
