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:
Using the Pinpoint Function (see "Locate a Target Using
Pinpoint Mode" on page 35)
Using a manual pinpointing technique
(see "Locate a Target Manually" on page 36)
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 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.
