Pinpointing
PINPOINTING METHODS
Pinpointing helps you to quickly narrow down the location of a buried target, allowing you to determine its exact location
before digging� There are two methods for pinpointing a target:
ƒ
Using Pinpoint Mode (see "Locate a Target Using Pinpoint Mode" )
ƒ Using a manual pinpointing technique (see "Locate a Target Manually" on page 31 )
PINPOINT MODE
When Pinpoint Mode is turned On, all targets are detected
regardless of the Discrimination Pattern and Ferrous Limits�
Pinpoint Mode also switches Off motion detection, so target
signals occur even when the Coil is stationary�
Pinpoint Mode progressively masks the target response by
reducing the Sensitivity with each sweep until only a very
narrow target response remains�
The detector's response indicates the strength of the target
signal directly below the coil� The difference in tone and
volume helps to locate the position and depth of the target�

The Pinpoint Bar
When Poinpoint Mode is enabled, the Pinpoint Bar will
appear at the bottom of the screen�
As the centreline of the Coil approaches the target, the
Pinpoint Bar fills from the outside towards the centre�
When the Bar is full, the target is directly beneath the
centreline of the Coil�
Weak/off‑centre target signal�
The target is located nearer to the
outside of the Coil� Strongest target signal� The
target is located directly below the
centreline of the Coil�
LOCATE A TARGET USING
PINPOINT MODE
1. Hold the Coil away from the approximate
target location�
2. From the Detect Screen, press (

) to turn On Pinpoint
Mode� The Pinpoint Bar will appear at the bottom of
the screen�
Keeping the Coil parallel to the ground, sweep slowly
over the target location two or three times� This
calibrates the detector for more accurate
audio responses�
3. Locate the centre of the target by listening for the
loudest signal and/or watching the Pinpoint Bar�
The Target ID and ID Map continue to update whilst in
Pinpoint Mode so that you can confirm that you are
pinpointing the correct target rather than
adjacent trash�
4. When the Pinpoint Bar fills all of the way to the centre
and the Pinpoint icon highlights, the target is below the
centre of the Coil�
If you have difficulty Pinpointing the target, or if the
detector becomes too noisy when Pinpoint is turned
On, turn Pinpoint Mode Off and then return to Step 1 to
repeat the Pinpoint procedure�
