For copper, iron, tin and other metal ore, composition and grade level cause different
signal, the operator can do experiment with a standard ore, to see reactions of it to
determine the distinction of ordinary rocks and minerals.
Detection Example
The description above of the mode of instrument operation, the operator can use the
instrument according to the specific circumstances.
Case 1
In an old house in search of deeply buried relics, for a long time due to the wide
variety of discarded metal debris such as nails, wire, old locks, pots and other debris
buried underground, these things are generally buried in shallow, the larger signal will
be issued, in order to exclude the debris away to detect buried deep targets. In this
case , we should first put metal furniture moved out of the house, a slight decrease of
the sensitivity of the instrument and carefully adjusted the balance . When the probe
found that there is a small metal debris will be cleared out, by over- meticulous
cleanup, after the shallow soil layer of metal objects dug up, then search of the deeper
site.
Case 2
In a place there are many scrap nails, detection signal emitted from nails everywhere,
that make the detection work is very inconvenient. Encountered such a situation, you
can put a nail on the ground in advance, then use the probe swept the top nails, if the
sound of the instrument increases,hold the reset button down, rotate left
( counter-clockwise ) a little of TUNE knob, release the button to explore once again,
if the sound is reduced , move probe away same as above, hold the button down,
rotate right ( clockwise) a little of TUNE knob, then release the button to move the
probe above nails test again, until adjust the sound unchanged. After a good tune, the
buried nails and smaller black metal than the nails sound of the instrument will not
increase, while all non-ferrous metal and black metal bigger than nails have a larger
signal sound.
Overview
Detection work is a meticulous and arduous job. It requires the operator to have
patience, confidence and perseverance. In practice, the detector is not able to detect
any metal objects underground show a clear picture, it is only able to predict about the
nature of the target position of the metal , or metal objects. In practice, the accuracy of
