Metal detectors work on the principle of conductivity and all metals are conductive. On the
other hand, soil itself has a certain degree of conductive property. Under certain
conditions, the conductivity level of the soil may be very high. Soil and rocks have
magnetic properties as well as conductivity. For this reason, when searching in soil and
between rocks, in order for the detector not to give a target signal for the soil, the detector
should be able to eliminate the soil and minimize the effects of rocks while still detecting
real targets. Otherwise, false signals and noise may mislead the user and make it
impossible to find the target. The purpose of ground balancing is to eliminate these false
signals and noise.
When you sweep the search coil over the ground, you can see whether the ground balance
is adjusted properly or not. However, if the signals and noise continue when the coil is
raised up, you must consider the possibility of the electromagnetic waves in the
surrounding environment. Electromagnetic waves may result from power lines or from the
operation of electrical devices, radars, wireless radios, and even TVs. In such a case, first
adjust the sensitivity and threshold. If the noise continues, shift the frequency to silence
the device and then ground balance.
NOTE: THE DEVICE WILL START IN TONE 4 IN FST AND BST MODES AND DIFFERENT
THAN THE OTHER TONE OPTIONS (TONE 1-TONE 2 -TONE 3 -TONE 5) , IT WILL
PROVIDE A SINGLE TONE ONLY. IN OTHER WORDS, THE DEVICE WILL PROVIDE 2
DIFFERENT TONES FOR IRON AND GOLD/NON-FERROUS METALS IN THE OTHER
TONE OPTIONS BUT IN TONE 4 IT WILL PROVIDE THE SAME TONE FOR ALL METALS
(GOLD, NON-FERROUS, FERROUS). THIS WILL ENABLE YOU TO HEAR SMALLER
GOLD NUGGET SIGNALS MORE CLEARLY.
When using the discrimination modes, if you record the IDs of the rocks in the
field and then mask them using the ID Masking feature, nugget detection will be
more convenient. When masking IDs, you must use the ID value closest to the ID
of the rocks. Otherwise, you may miss the nuggets under the rocks.
Consequently, you may need to change the default ID masking value(10) of this
mode to another value based on the IDs of the rocks in the field. For more details
on eliminating hot rocks, please read the related sections (Target ID and ID
Masking, Hot Rocks and Searching in Rocky Areas, and Metals Under Hot Rocks).
If you dig a target signal in a gold field and find rocks, be sure that there is no
small gold nugget underneath.
To get familiar with the warning audio tones, we recommend you to test the
device with different metals and hot rocks before you use it in the field.
