Attention!
All of the above procedures are necessary when making changes
to the software version (flashing).
Frequency switching of 3 frequency sensors.
In order to switch the operating frequency of a 3-frequency sensor
1. Turn off the device.
2. Switch the frequency switch of the control box to the desired frequen-
cy.
3. Turn on the device with the button
held down, as de-
scribed in the Chapter Replacement
of the sensor.
4. Carry out ground balance.
If your device is equipped with several periodically used sensors (coils),
we recommend that, in case of some interruption (for example, season-
al), restart the detector before starting the search, i.e., to avoid confu-
sion, adapt the control box to the sensor (coil).
SEARCH AND IDENTIFICATION METHODS
When scanning the ground move the coil smoothly over the surface of
the ground while maintaining a constant distance of 2-3 cm
.
This
distance is optimal from the viewpoint of suppressing the influence of
ground mineralization, and hence, for the proper identification of the
metal objects. Avoid touching the ground with the coil. It is important
that the distance between the coil and the ground remain constant (see
Figure 16).
Keep in mind that the quality of this operation has a direct impact on
the correct identification of desired targets. Also try not to make sudden
movements of the coil horizontally. Optimal scanning speed is 40-50
cm/s. Each pass of the sensor should overlap the previous one.
Use additional scans to more accurately identify the type of object by
centering above the target. Sweep the coil through the maximum signal
area as accurately as possible maintaining a constant distance between
the coil and ground. For the same reason scan the target with coil in the
direction of the least amount of surface change in the ground. In this
