PINPOINTING THE OBJECT
Introducing Pinpoint
Figure 5.20. See also Pinpoint overview in Chapter 4: Control Panel, page
34.
During normal operation the Explorer II operates with discrimination
settings like Iron Mask or targets chosen from the Select target list.
When the approximate location of a target has been determined, it is
necessary to identify the object’s exact position. This is done using
the Explorer II’s Pinpoint function.
Enabling Pinpoint instructs the Explorer II to temporarily disengage
discrimination and become an ‘all metal’ detector. This means that
objects normally discriminated against will emit a target signal when
beneath the coil.
For example, Iron Mask is activated and the Explorer II has
detected the approximate location of a non-ferrous coin but ignored
the rusty nail buried nearby. Selection of Pinpoint instructs the
Explorer II to respond to all metals positioned directly beneath the
coil. Now, instead of a single signal for the coin the detector will also
respond to the nail.
It should be noted that the Pinpoint function is designed to zone in on
a target with subsequent passes. For this reason it is recommended
that you maintain the same sweep height above the target and not to
pass repeatedly back and forth across the target at various heights.
This incorrect method can cause the detector to desensitize and
reduces the depth of Pinpoint. If this happens, remove the coil from
the area of the target for a few seconds so its sensitivity can recover.
For this reason, Minelab recommends Pinpoint is only used
once the approximate location of a target has been
determined. The display screen’s Pinpoint indicator will flash to
remind you to turn Pinpoint off before resuming normal detecting.
Instructions for the use of Pinpoint appear on the following page.
