Pinpointing - Garrett AT Pro Owner's Manual

Press and hold the Pinpoint pushbutton to determine
the exact location of a target. To use the pinpoint function,
position the searchcoil to the side of the target's suspected
location at a fixed height above the ground (e.g. 2cm). Press
and hold the Pinpoint button and sweep the searchcoil over
the target area while maintaining the same fixed height
above the ground (e.g. 2cm). Sweep the searchcoil side-
to-side and front-to-back in a crosshair pattern to locate
the peak signal. Note: it is recommended to maintain a
constant height during the entire Pinpointing process to
prevent ground mineralization from producing false signals
or masking the target's signal.
The bar graph on the LCD can also aid in locating the peak
signal. When pinpointing, the Upper Scale on the LCD Screen
indicates signal strength. When the greatest number of LCD
segments (increasing left to right) are shown, the center of
the searchcoil is directly over the target with the depth of a
coin-sized target shown on the depth scale. The symbol "PP"
for pinpoint is displayed on the LCD while pinpointing.
It is recommended to practice pinpointing in a test plot.
Note: The center of
detection is under
the center of the coil,
just ahead of its stem
mount. The opening
just ahead of the stem
mount can serve as
your reference point
for pinpointing.
