• Press and hold the PINPOINT button and the PINPOINT indicator
will light up. The coin depth indicator shows [8+]. The upper and lower
scale displays will all go out. The detector will emit a deep tone. If the
displays do not go out, release the PINPOINT key and try again.
• Once in PINPOINT mode, move the search coil slowly near the object
until a high signal strength indicates the exact position. Once the
position is determined, the sound will become louder and the target
depth indicator will brighten.
• Hold the detector firmly in this position and release the PINPOINT
key. Press the button again after a few seconds. The indicator will
go off and a single low tone will sound. Move the search coil slowly
around the target until the sound becomes louder and the depth
indicator brightens again.
• Repeat this process several times until the exact position and depth
are known.
• When a depth of 2-4" is displayed, the subject is close to the center of
the search coil.
Note: In PINPOINT mode, the depth indicator becomes the signal
•
strength indicator at the same time.
(7) Adjust ground balance
Before using the PINPOINT mode, use the ground balance button to
adjust the detector. This helps to eliminate minerals in mineral-rich soils.
• Find a metal-free area of the soil. Set the ground balance setting to [P].
• Lift the search coil more than a meter above the ground (see picture).
Press the PINPOINT button and bring the coil to about 1.5 cm above
the floor.
