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) Press and hold down the PINPOINT button, the detector will sound a
low single-frequency tone, and the sensitivity is in the highest state.
b) Let the search coil approach the ground, when you find the target,
move the search coil slowly in the region. 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 louder, and the signal strength cursor is full scale.
c) Maintain the position of the detector, release the PINPOINT button
for several seconds. Press the PINPOINT button again, the detector is
self-balanced, and sounds a slight single frequency tone, the signal
strength cursor is extinguished. Move the search coil slowly again, let
the single frequency tone turn louder, and the signal frequency cursor
gets more.
d) Repeat the operation and approach the target, 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 into 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 position of 2”. In fact, it
means the target is the nearest from the center of the search coil.
