6. PINPOINT
When detecting in the motion mode,as you should persistently move the
search coil,so although you find the region that burying metals,it’s not easy
for you to determine the exact location,it gets the digging difficult.At this
time,you should recur to the PINPOINT mode.
a) Touch the PINPOINT button,the PINPOIT cursor is lighted,and the depth
cursor will be full scale.The detector will sound a low single-frequency
tone,the sensitivity is in the highest state.
b) Let the search coil approach the ground,move the search coil slowly in the
region,where you find the target.In the position where the single frequency
tone turns louder,and the signal strength cursor begins to appear.Continue
moving the search coil slowly until the sound turns more louder,the signal
strength cursor is full scale,and the depth cursor is the lowest.
c) Maintain the position of the detector,exit the PINPOINT mode.Touch the
PINPOINT button again later,the detector will be self-balanced,and sound a
low single frequency tone,the signal strength cursor will be extinguished,the
depth cursor will be full scale.Move the search coil slowly again,let the single
frequency tone turn more louder,and the signal strength cursor increase,the
depth cursor turn to the lowest,which means the position of the metal target
has been locked.By the center of the open search coil,mark on the ground,to
facilitate mining.
d) Repeat the operation for several times and approach the target for several
times,until you lock the location of the metal target.You could make notes on
the ground by the center of the open search coil,to facilitate your excavation.
e) In the process of the PINPOINT,the depth cursor will turn to the signal
strength cursor,which denotes the distance between the center of the search
coil and the target,to help you pinpoint the location.Finally,the depth cursor
will remain at the lowest gear.In fact,it means the target is the nearest from
the center of the search coil.
7. Depth and Target Indication(only in the motion mode)
The detector is preset in the motion mode,The LCD screen will show the
rough metal target types and the rough target depth.
When the position and type of the target are determined,the detector will
send a repeated signal.If you detect in the same place,while the
discrimination display is inconsistent,which means the target may be false,or
it may be the trash metal or heavily oxidized metal.Trough practice,you must
bear in mind only repeatable signal existent,then you do excavation.
When find a metal target,the identification cursor will indicate the metal
type.Silver is on the right.In the neutral soil,the identification indication is
more accurate,while in the mineralization or salinization soil,the
discrimination indication will have various degree of deviation.
