(IN CONTROL BOX)

CODEC SIGNAL CONVERSION

The X-Terra detecto rs are Minelab’s fi rst products
to incorporate VFLEX Technolo gy.

VFLEX uses st ate of the art digital a nd mixed-signal
components to enhance standard single frequency
technology by replacing most of the analogue
circuitr y with digital signal pr ocessing. The small
amount of anal ogue circuitry st ill employed has
been very carefully designed and calibrated to
obtain the outstanding sensitivity, stability and
repeatabi lity required to match th e performance
of the processing in the digital domain.

This radic al departure from tr aditional approa ches
to metal detector design has been made possible
by advances in e lectronics that p ower personal
digital assistants, cell (mobile) phones and
high-fi delit y portable audio.

For the X-Terra user, this pre cision means
dependable performance and improved immunity
to environmental conditions such as ground
mineralization, electromagnetic interference
and temperature variations.

VFLEX requir es coils that are accurately con structed
and calibrated. Every time the detector starts up,
the micro- controllers in the contr ol box and the
coil establi sh communication throu gh a digital
data link.

Informatio n about the coil is sent to the cont rol box,
so the detector ‘knows’ what type of coil is attached
and can set the co rrect operating p arameters.

This optimi zes the performan ce, and also makes
the detector ‘future proof’, in that it will be capable
of operating at diff e rent frequencies* d epending
on the electronic properties of the coil.

Plug the two rubber washers into the holes
on either side of the lower shaf t yoke.

Slide the yoke into the yoke bracket on top
of the coil. Ensure that the spring loaded
pin in the lower shaft is underneath.

Insert the plastic bolt through the yoke
and the yoke bracket.

Fasten with the plastic wing nut provided,
being careful not to damage the thread
of the bolt by over-tightening. This may
need to be loosened to adjust the coil to
a comfortable detecting angle.

The coil cable is directly wired into the
coil and is not removable. Any attempt to
disconnect this cable will void your warranty.

Ensure that the twistlocks of the shaf ts
are loosened by rotating them counter­clockwise.

Compress the spring loaded pin in the
lower shaft and slide it into the middle shaft
until the pin reaches the adjustment holes.
The pin will spring out and click into place.

Attach the middle shaft to the upper
shaft in the same way.

Once shafts are assembled, lock them in
position by rotating twistlock s clockwise.

The upper shaft assembly location uses
two spring loaded pins to strengthen the
joint, one on either side of the shaft

10

11

Place the armrest onto the top of the upper
shaft, lining up the central hole in the
armrest with a hole in the aluminium shaft.
Position the armrest to suit your arm length.

(Holding the Detector, pg. 15)

Insert the screw up through the stand, upper
shaft and armrest. Tighten the screw, being
careful not to overtighten and damage the
thread.

With the velcro side facing upwards, thread
the armrest strap through both slots in the
armrest. Ensure the end of the strap will
be fastened outwards from your arm.

Connecting

With the LCD facing up, push the control
box onto the end of the handle until it
fi ts into place.

The X-Terra is designed to be used in both the
left and right hand. This diagram shows the
velcro strap threaded outwards for the left arm.

10

The LCD window has a protective
fi lm affi xed to prevent scratching.
This may be removed when the
detector is fully assembled.

The control box may be easily removed
for packing and transport in a carry bag.

Disconnecting

Brace the detector fi rmly against
yourself, grasp the control box and
pull it away from the handle.

13

Wind the coil cable around the lower
and middle shaft enough times to take
up the slack.

Use the velcro tabs to keep the coil cable
in place against the shaft. It is recommended
that one tab is used on the lower shaf t close
to the coil and the other tab on the middle
shaft before the cable reaches across to
the control box.

Align the coil plug and connect into
the socket in the back of the control box,
lightly tightening the retaining ring to
hold it in place.

The X-Terra uses 4 X AA batteries which
are not included with the detec tor.

(Battery

Behaviour, pg. 62)

Access the battery compartment via the
battery door located on the side of the
control box. Slide the batter y compartment
door upwards with your thumb.

Place individual batteries into the
compartment as illustrated, ensuring
the positive (

+) and negative (–) contacts

match the diagram on the control box.

Close the battery door by pushing and
sliding it downwards.

12

If the detector does not turn on check the
battery orientation. The detector will not
be damaged if the batteries are inserted
incorrectly.

CONGRATULATIONS!
YOU HAVE SUCCESSFULLY
ASSEMBLED YOUR X-TERRA.
IT IS NOW READY FOR DETECTING!

14

Thread your arm through the armrest
and strap. Grasp the handle of the detector
and rest your forearm in the armrest.

Your elbow should sit just above the top
of the armrest. Lightly tighten the velcro
strap and secure it around your arm.

17

Shaft is the

correct length

Shaft is too short

The correct position of armrest and length
of shaft should allow you to swing the
coil in front of your body without any
uncomfortable stretching or stooping.

To adjust the length of the shafts, undo the
twistlocks, compress the spring pins of the
shafts and move them up or down to suit.
Once all shafts are clipped into position,
rotate twistlocks clockwise onto the shafts
until a fi rm clamping action is achieved.

(Shaft Assembly, pg. 9)

To adjust the position of the armrest
remove the armrest screw and move the
armrest and stand to the desired position.

(Armrest Assembly, pg.10)

Think of the detector as an extension of
your arm. It should be straight with your
forearm and feel light and comfortable
when you pick it up.

coil parallel to the ground

Once outside, practice sweeping the coil
over the ground in a side-to -side motion,
while walking forward slowly. Slightly overlap
the previous sweep to ensure a full ground
coverage. An approximate sweep speed is 3
seconds from lef t to right to left.

It is important to keep the coil close and
parallel to the ground at all times. This will
increase detection depth and response to
small objects. Avoid excessive brushing
of the coil on the ground, as this may result
in false signals and inaccurate target ID’s.

A variation in coil height at the end of each
swing may also cause confusing sounds and
reduce detection depth.
