ASSEMBLY
Assembly is easy and requires no tools.
●
1
Position the lower stem (the straight tube)
with the silver button toward the back.
Using the bolt and knurled knob,
attach the search coil to the
lower stem.
●
2
Twist locking collar on upper
stem to open.
●
3
Press the button on
the upper end of
the lower stem,
and slide the lower
stem into the
upper stem.
Adjust the stem to a length
that lets you maintain a
comfortable upright
posture, with your arm
relaxed at your side, and
the search coil parallel to
the ground in front of you.
●
4
Wind the cable securely around the stem.
●
5
Insert the plug into the matching connector on the right
underside of the detector body. Be sure that the key-way
and pins line up correctly.
●
5
Twist locking collar to
tighten connection
between poles.
Caution:
Do not force the
plug in. Excess force
will cause damage.
To disconnect the
cable, pull on the
plug.
Do not pull
on the cable.

If the detector emits sound with the coil over the ground in STEP 56,
further adjustment of the ground balance KNOB is required as follows:
• Lift the search coil waist high
• Rotate the ground balance KNOB clockwise 1/16 of a turn
• Press PINPOINT
• Lower the search coil to the ground again
If the detector still emits a tone, repeat the procedure. You are searching
for the ground balance knob positiion where the detector is
just silent.
It is important to move the knob in small increments in order to find
the first setting (moving clockwise) at which the detector remains
silent. To insure yourself of the optimal adjustment, move the KNOB
slightly counterclockwise from a silent-adjusted position to check for
the
most counterclockwise silent position possible.
If the KNOB is over-adjusted in the clockwise direction, the detector
can lose sensitivity. An over-adjusted condition can also cause the
detector to sound off when the coil is lifted away from the ground.
As your search takes you to different areas, verify the ground balance set-
ting periodically using the above procedure. Within a geographical area,
ground conditions can change. Varying elevation, proximity to water, and
concentration of rock, sand or clay can all affect ground condition and
sometimes require recalibrating with the ground balance knob.
• If the detector remains silent with the search coil 1/2 inch over the
ground, no further adjustment is necessary; the detector is
“GROUND
BALANCED”
If the KNOB is over-adjusted in the clockwise direction, the detector
can lose sensitivity. An over-adjusted condition can also cause the
detector to sound off when the coil is lifted away from the ground.
