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.

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

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.
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 left to right to left.

It is important to keep the coil close and
correct length
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.
