Pinpoint
Pinpointing helps you to quickly narrow down the location
of a buried target, allowing you to determine its exact
location before digging�
Pinpointing can be done in two different ways:
ƒ Using the Pinpoint Function (see "Locate a Target Using
Pinpoint Mode" on page 42 )
ƒ Using a manual pinpointing technique
(see
"Locate a Target Manually" on page 43 )
The difference in tone and volume will help to identify the
position and depth of the target�

PINPOINT MODE VISUALISATION
When Pinpoint Mode is turned On, the discrimination
pattern is temporarily disabled (i�e� All Metal is enabled)�
Pinpoint Mode also switches Off motion detection, so
target signals occur even if the coil is stationary�
As the centreline of the coil approaches the target,
discrimination segments will fill from the outside towards
the centre� When the Discrimination Segments are all On,
the target is directly beneath the centreline of the coil�
Weak/off-centre target signal: Fewer
discrimination segments are On�
The target is located nearer to the
outside of the coil� Strongest target signal: All
discrimination segments are On� 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,
then press the Pinpoint button once to turn Pinpoint
Mode On� The Pinpoint Indicator cross-hairs will appear
on the display�
2. Keeping the coil parallel to the ground, sweep slowly
over the target location two or three times� This
calibrates the Pinpoint function for more accurate
pinpoint audio responses�
3. Locate the centre of the target by listening for
the loudest signal and/or watching the Pinpoint
Visualisation on the display�
Note: The Target ID will continue to update whilst in
Pinpoint Mode, allowing you to confirm that you are
pinpointing the correct target and not an adjacent
trash object�
Note: the Pinpoint function progressively masks the
target response by reducing the Sensitivity with each
sweep until only a very narrow target response remains�
4. When all of the segments on the Discrimination Scale
are On, the target will be 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 Off Pinpoint and then return to Step 1 and repeat the
Pinpoint procedure�
