2. Place the machine on a wooden or plastic
table. Remove jewellery, watch and other
metal objects from your hands and arms.
3. Place the search coil with the flat part
upwards.
4. Activate DISC, NOTCH or AUTO-NOTCH
mode and move the nail smoothly 10–12
cm over the flat part of the search coil.
The machine emits an audio signal with
a low tone level when the test object is
detected and the arrow for nails goes
on in the target reading. The depth
reading shows a similar value. Repeat
the test with a 1-cent coin (after 1982).
The machine emits an audio signal with
a medium high tone level and the arrow
in the target reading points to 1¢. Repeat
the test with a 25-cent coin. The machine
emits an audio signal with a high tone
level and the arrow in the target reading
points to 25¢.
NOTE:
• If a coin is used for the test it is best to
put the flat surface of the coin parallel to
the search coil and move past the search
coil with a smooth motion. This makes
the target easier to detect.
• If the edge of the coin is moved past the
search coil the test will fail, and the
target reading arrow may flash and
move.
In ALL METAL mode hold a test object at least
35 cm over the search coil and move it slowly
towards the flat surface of the search coil.
The machine emits an audio signal when the
target is detected and the depth reading shows
a relative value. In this mode the same audio
signal is generated for all test objects.
Testing and practice outdoors
Precise localisation (motion mode)
Precise localisation requires practice. The
simplest way to precisely locate a target is to
move the search coil crosswise over the target
area.

1. When a buried object is clearly indicated
continue to move the search coil over
the target with increasingly shorted
movements from side to side.
2. Note the point on the ground over which
the audio signal is heard.
3. Hold the search coil still directly over this
point.
4. Now move the search coil backwards and
forwards a few times. Note the point on
the ground over which the audio signal is
heard again.
5. If necessary move the search coil in a
crosswise pattern at different angles over
the target area to more precisely locate
the point over the ground where the
audio signal is heard.
Moving the search coil
Make sure to keep the search coil parallel to
the ground, 1–1.5 cm over the surface. Do not
allow the search coil to swing up and down.
FIG. 11
If the search coil lifts at the end of it movement
this will generate a false signal. Move the
search coil sideways, backwards and forwards
7–8 cm. Move the search coil slowly over the
ground and overlap the swings while moving
forward.
FIG. 12
It is important to move the search coil at a
steady speed over the ground. When a target
has been found this technique is critical to
identify and precisely locate the target object.
If the signals are weak move the search coil
with short, quick movements over the target
area – this can produce more precise target
identification.
Most objects worth digging up generate a
repetitive audio signal. If the signal is not
