Pairing the ML 100 headphones
START 
1. Make sure headphones are off, and
close to the detector.
Ensure the headphones are turned off
and are no more than 1 metre (3.3 feet)
away from the detector.
2. Turn on the headphones
and enter pairing mode.
Press and hold the Multi-Function button
on the headphones until two ascending
tones are heard and the Status LED
alternates blue and red.
3. Enable Bluetooth® on
the detector and enter
pairing mode.
Press and hold the Bluetooth® button on
the side of the GPX 6000™ control panel
until the Bluetooth® indicator begins to
flash rapidly.
For first-time use of the detector or
following a factory reset, a short press
of the Bluetooth® button will immediately
initiate the pairing sequence.
4. Headphones will
automatically connect.
If pairing is successful, the headphones
beep, and the Bluetooth® and wireless
headphones indicators will remain on.
The Status LED on the headphones will
flash blue once every 3 seconds during
use.
To Factory Reset the ML 100 headphones,
press the Multi-Function button for more
than 10 seconds. All previous pairings and
settings will be deleted.

Intelligent Automatic Operation
The procedure below is a fail-safe way
to begin detecting in a high-sensitivity
automatic mode. Once complete, the
GPX 6000™ will automatically maximise
sensitivity while minimising noise, so you
can concentrate on finding gold.
START 
1. Factory Reset the
detector.
Long-press for at
least 7 s
2. Hold the coil 100 mm
(4 in) above the ground. 100 mm (4")
3. Raise and lower coil for
10 seconds.
 Begin detecting.
Every 5 to 10 minutes throughout your
detecting session, it is recommended
that the coil is raised and lowered above
the ground a couple of times from
10 to 100 mm (⁄ to 4 in). This ensures
that the detector is thoroughly ground
balanced and operating at maximum
sensitivity. In environments with more
ground noise, repeat this process more
frequently.
 If the conditions are very quiet,
increase sensitivity from Auto to
Auto+.
 If the detector becomes noisy,
conduct a Noise Cancel Procedure.
 If this doesn’t resolve
the noise, follow the
Double-D Coil Noise Cancel Procedure.

Manual Sensitivity Adjustment
Procedure
Always try the
Noise Cancel Procedure and the
Quick-Trak Ground Balance Procedure to
resolve noise before reducing the
sensitivity level.
Generally start with a Mono coil unless
you are detecting in areas with known
high levels of EMI or soil conductivity.
START 
1. Set sensitivity to
level 1.
2. Increase until false
signals occur.
3. Reduce by one level.
4. Check over ground and
reduce if needed.
Return to Contents

Noise Cancel Procedure
If audio responses become erratic due to
EMI, initiate the Noise Cancel process to
automatically select a quieter detecting
channel.
START 
1. Hold the coil 100 mm (4
in) above the ground. 100 mm (4")
2. Press the
Noise Cancel button.
3. Wait for confirmation
tone (approximately
5 seconds).
 Begin detecting.
 If the detector is still noisy when
using a mono coil, follow the
Double-D Coil Noise Cancel Procedure.
Return to Contents

Double-D Coil Noise Cancel
Procedure
Generally, a Double-D coil should only be
used if noise cannot be managed by using a
Mono coil with the Noise Cancel Procedure.
This procedure can be used in areas that
have known high levels of EMI or very
conductive (salty) soils.
START 
1. Connect the GPX 14™
Double-D coil.
2. Hold the coil 100 mm
(4 in) above the ground. 100 mm (4")
3. Turn the detector on.
4. Set the Double-D mode
to EMI Cancel. Long-press for at
least 2.5 s
5. Hold the coil still above
the ground and assess
noise levels.
 Begin detecting.
 If the detector is still noisy, continue
to the next step.
6. Noise Cancel.
 Begin detecting.
 If the detector is still noisy, continue
to the next step.
7. Reduce the
sensitivity level.
 Begin detecting.
 If the detector is still noisy, change to
an Auto sensitivity setting (Auto or
Auto+).

Quick-Trak Ground Balance
Procedure
Follow the Quick-Trak Ground Balance
procedure to quickly recalibrate the
detector to the new ground.
START 
1. Press and hold the
Quick-Trak button.
2. Raise and lower
the coil until noise
reduces.
3. Swing coil the from
side-to-side.
4. Release the
Quick-Trak button.
 If there is still noise when the coil is
passed over the ground, follow the
Ground Balance Procedure.
 In some cases, try detecting on a
nearby location in case the noise
is being caused by a target /
metal object. Try performing the
Quick-Trak Ground Balance Procedure
over a new patch of ground.
Return to Contents

Ground Balance Procedure
A complete Ground Balance procedure
is recommended below. This guides you
through the ideal steps to deal with a
number of different ground conditions.
START 
Normal (Quiet) Ground
1. Set the Ground Type to
Normal.
2. Quick-Trak.
3. Adjust the sensitivity.
 Begin detecting.
 If the detector is still noisy when
the coil is raised and lowered just
above the ground, then noise is the
result of difficult or variable ground
conditions. Continue the steps below
for Difficult/Variable Ground.
Difficult/Variable Ground
4. Set the Ground Type
to Difficult.
5. Quick-Trak.
6. Adjust the sensitivity.
 Begin detecting.
 If the detector is still noisy when
detecting, then noise is the result of
conductive (salty) ground conditions.
Continue the steps below for
Conductive (Salty) Ground.
Conductive (Salty) Ground
7. Change to a
Double-D coil.
8. Turn the detector on.
9. Set the Double-D
mode to Conductive
Ground Cancel. Long-press for at
least 2.5 s
10. Quick-Trak.
11. Adjust the sensitivity.
Begin detecting.
