c) Maintain the position of the silver coin,release the PINPOINT button,exit
the PINPOINT mode.Press the PINPOINT button again after several
seconds,the signal strength cursor is extinguished,and the sound comes
back to the initial state,the depth indication comes back to the full scale.
d) Let the silver coin move to the center of the search coil again,the signal
strength cursor appear again and increase,the sound turns louder,and the
depth cursor goes lower,which means the metal target is more closer to the
center of the search coil.Up to now, a “PINPOINT” operation has completed.
e) To the samples with different materials,the detector will give the similar
respond.
After doing this steps,you have an initial familiarity to the detector,and you
can begin the next step of basic operation.
Basic Operation
Metal detector is used outdoors.There is too much metals indoors,and all
kinds of electrical equipment that will bring interference signals.So it is not fit
for using the detector indoors.
Field detection is more complicated,the composition of the regional soil,the
component,size,shape and the oxidation degree of the underground metals
will all affect the detection results.This chapter is only the general steps of
the field detection.You should operate again and again, accumulate
experience to achieve good results.
1.
Turn On
Hold the detector,keep the search coil be away from the ground.Press the
Power button,the detector will sound two moo tones,and all the LCD patterns
are lighted at minutes.Then the sensitivity will be set to the second gear,and
the operation mode will set to ALL METAL.Prompt once again,don’t
operate,nor let the metal approach the search coil,until the balance has been
completed,and sound a tone.
2.
Set the operation mode
In generally,you could choose the ALL METAL mode.At this time,the detector
will make identification response to all kinds of metals.
Since the soil will make the detection indication deviate,we suggest you bring
some samples,such as 25
￠
silver coins, 5
￠
nicker coins and so on.Bury
these samples in the soil of the detection region respectively,try to
detect,observe the position of the discrimination cursor appear,and how
much deviation from the target pattern.It will help you judge the type of the
target,in case you omit the treasures that you want to find.
Directly with the PINPOINT to detect,it is also an alternative way.Specifically
in the region where the ground is more complicated or in the venues where
the electromagnetic interference is larger,the effect may be more better.
