Alternative Pinpointing Methods - Garrett AT Pro Owner's Manual

• Alternative pinpointing technique: DD-tip or tail. In the
standard pinpointing method described on pages 34, the
target is pinpointed beneath the center of the searchcoil.
Some detectorists using DD coils prefer to pinpoint off the tip
or tail of the searchcoil.

Press and hold the Pinpoint
pushbutton and sweep the
searchcoil side-to-side to center
the target (the point where the
strongest audio response is
heard and the maximum signal
strength is displayed on the LCD).
Then, pull the searchcoil slowly
toward you (see Image A), while
noting the target signal.
Once the target signal drops off
Image B
(both audibly and on the LCD
meter), shallow targets should
be located immediately in front
of the searchcoil's tip (see Image
B). Deep targets will be under or
just inside your searchcoil's tip.
This is because the conical shape
of the searchcoil's detection field
begins bending in slightly as the
depth increases.
