MINERAL MODES
Mineral Modes: If you are searching on high mineralized ground (extremely salty soil, wet
beach sand, wet plowed land or highly magnetic ground conditions) you may not be able to
ground balance the device. In such a case, first turn the On/Off knob to mineral 1. If the device
is still getting noise, turn it to mineral 2 or mineral 3. This will eliminate the noise and false
signals caused by mineralization. However, you may experience a decrease or fading in the
signal obtained from certain metals at maximum depths.
As mentioned before, especially on grounds with high iron content such as wet salt water
beach sand and wet plowed land, it is recommended that you search in mineral 2 or 3 mode,
bring the iron discrimination to maximum level and turn the iron switch off.
SIGNAL AUDIO BOOST
Please note that signal audio boost should be used on a temporary or as-needed basis because it will not only boost the
target signal audio but it will also boost the loudness of ground noise and false signals. Therefore, it is recommended to keep
the switch at position 1 and turn it to position 2 or 3 only when you want to verify a weak metal signal and then turn it off
again.
The signal audio boost switch boosts the sound of weak signals received from small or deep
metals making it easier for you to detect those uncertain targets.
At position 1, the booster is off. At 2, the signal audio will be higher and at 3, it will be heard
at its maximum.
In general, when searching in wet salt water beach sand, the most ideal settings are the maximum level of the iron discrimination,
iron switch off and mineral 2 or 3 modes. You can also use these settings when searching in wet plowed land with high iron effect.
2) It enables metals containing iron to produce a low tone and to be discriminated more easily. Discrimination starts at about
level 4 - 6. Below this level, all metals including iron will produce a non-ferrous (high) tone and generally speaking the device will
perform at its maximum depth. In addition, iron switch will not be active below this level.
