For the best
pinpointing results,
maintain a constant
height above the
ground (e.g. 1 inch).
Note: Use of the Pinpoint button is demonstrated on the
AT Max
training video, which can be seen at garrett.com.

• Alternative pinpointing technique: DD-tip or tail.
In
the standard pinpointing method described on pages 41, 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 button 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 coil slowly toward you
(see
Image A)
, while noting the target signal.

Once the target signal drops off (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.
You can reverse this pinpointing technique to pinpoint off the
DD coil's tail; in this case, push the coil away from you. The audio
and LCD meter will place the target just off the searchcoil's tail.
