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.

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.
