Traditional pinpointing technique using Pinpoint pushbutton.
Note: It is important to maintain a constant searchcoil height
above the ground (e.g. 2cm) during the entire Pinpointing
process to prevent ground mineralization from producing
false signals or masking the target's signal.
• Alternative pinpointing technique: DD-wiggle. Quickly
locate targets without using the Pinpoint button as follows.
Continuously swing the searchcoil side-to-side using fast,
narrow swings of 5–10cm (i.e. wiggle). While continuing
this side-to-side wiggle, slowly move the searchcoil sideways
toward the target's suspected position until the audio
response produces a consistent, symmetric beat. This
indicates the lateral left-to-right position of the target. Then
locate the target's front-to-back position by rotating around
90° and repeating the same process.

• Alternative pinpointing technique: DD-tip or tail. In the
standard pinpointing method described on pages 15 and 31,
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.

(Left) Press and hold the
Pinpoint pushbutton during this
technique. Sweep the searchcoil
side-to-side to center the target
(the point where the strongest
audio response is heard and the
maximum LCD pixels on the top
row are displayed).
Then, pull the searchcoil slowly
toward you, while noting the
target signal (see Image A).
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 (see Image C).
