balanced. The target ID cursor in the upper cursor and the target
discrimination cursor in the lower cursor are all extinguished, and
the depth cursor is full-scale, the detector will sound a slight single-
frequency mediant.
b. Let the silver coin approach the search coil slowly, in the position of
about 7"-8", the first group of signal strength cursor begins to appear,
and the sound turns louder. Continue let the 25 ¢ silver coin approach
the search coil, and the signal strength cursor is full-scale quickly,
the sound is more louder, then the depth cursor denotes the depth
dropping, until one is left, which means the metal is gradually close to
the center of the search coil.
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.
