To hold the detector, 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.
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.
Shaft is the
correct length
Shaft is too short
Once outside, practise sweeping the coil
over the ground in a side-to-side motion,
while walking forward slowly. Slightly
overlap the previous sweep to ensure
full ground coverage. An average sweep
speed is three seconds from left to right
to left.

HOLDING THE DETECTOR
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 they are firmly clamped
(Shaft Assembly, pg. 5).
To adjust the position of the armrest
remove the armrest screw and move the
armrest and stand to the desired position
(Armrest Assembly, pg. 6).
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.
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.
SWEEPING THE COIL
The X-Terra 70 coil is waterproof.
(Care of Your X-Terra 70, pg. 52)
Try sweeping the coil faster in Coin &
Treasure Mode for improved target
detection and identifi cation.
Try sweeping the coil slower in
Prospecting Mode for improved target
detection and separation from ground
mineralisation signals.
