Note: For comfortable,
long term detecting, it is
important you take the
time to adjust the
detector correctly.
Adjusting the Detector
for Comfortable Detecting
Adjusting the Battery Harness:
A comfortable fitting battery harness will ensure the
longest detecting session possible without fatigue.
Ideally the battery should be placed on your back so
that it counter-balances the weight of the detector.
You should be able to reach the switches of the
detector without putting excess strain on the
bungy cord.
Pull the straps outwards and downwards to tighten.
Push the straps back through the buckle to loosen.
The harness may also be adjusted around your body
by threading the front straps through different loops
on the waistbelt.
Adjusting the Bungy Cord Clamp
(Bow Knuckle):
The correct position of the bungy cord clamp (bow
knuckle) along the shaft can help take the weight of
the coil.
Loosen the clamp screw so it can slide along
the shaft. Slide it to a position that feels most
comfortable for you.
Note: You may need to change the length of the bungy
cord, or the position of the bungy cord clamp, when
you change coils or detect on sloping ground.
Holding the Detector:
Thread your arm through the armrest and strap.
Grasp the handle of the detector and rest your
forearm in the armrest.
Adjusting the Position of the Handle:
Your elbow should sit just above the back of the
armrest allowing you to comfortably grip the handle.
Slide the handle into position. Using a screwdriver,
tighten the two screws which hold the handle
onto the shaft. Adjust the handle strap to a
comfortable position.
Adjusting the Length of the Lower Shaft:
If the coil is too far from your body it will be difficult
to balance and manoeuvre while detecting.
If the coil is too close to your body it may detect your
pick, the battery, or any other metal which you are
carrying; causing confusing sounds.
Rotate the twistlocks of the shafts counter-clockwise
to ensure that they are loosened.
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
.
The correct length of the lower shaft should allow
you to swing the coil in front of your body without
any uncomfortable stretching or stooping.

Tip: Some operators may
find it more comfortable
to fit the battery around
the waist. However, make
sure the GPX-4500 isn't
detecting a signal from the
battery. If using a large coil,
position the battery as high
up on your back as practical
(and comfortable) to avoid
any unwanted interference.
