Frequency Shift
It is used to eliminate the electromagnetic interference
that the device receives from another detector which
operates in the same frequency range nearby or from
the surroundings. If too much noise is received when
the search coil is lifted in the air, this may be caused
by the local electromagnetic signals or excessive gain
settings.
To eliminate the noise caused by electromagnetic
interference, try shifting the frequency first before
lowering the sensitivity to obtain maximum depth
performance. Frequency shift consists 3 small steps
(F1-F2-F3). Default setting is F2 which is the central
frequency. The selected frequency will be highlighted
in black.
To shift the frequency, after selecting the Frequency
Shift in the settings menu, use the plus (+) and minus
(-) buttons.
This setting is common in all modes; change made in
any mode also applies to the other modes.
IMPORTANT! Frequency shift may impair performance.
Therefore, it is suggested that you do not shift the
frequency unless it is necessary.
Threshold
In the All Metal mode, search is performed with a
continuous humming sound in the background, also
referred to as the threshold sound. The loudness of this
hum directly impacts the detection depth of smaller
and deeper targets and it is adjusted by the threshold
setting. If the threshold is set too high, a weak target
signal may not be heard. On the contrary, if the threshold
is too low, you give up the depth advantage this setting
offers. In other words, weak signals of smaller or deeper
targets may be missed. It is recommended for average
users to leave this setting at its default value and for
experienced users to adjust to the highest level where
they can still hear the weak target signals.
You can adjust the threshold setting between -50 +50
based on ground conditions. To adjust the Threshold
setting, use the plus (+) and minus (-) buttons after
selecting the Threshold in the settings menu.
0
Threshold setting can only be used in the All Metal
mode and thus cannot be selected in other modes.
