The CS440XD is a lightweight professional format metal detector.
A variable discrimination control (16) can be adjusted so that the detector does
not react to some types of metal which are likely to be worthless. The CS440XD is
extremely easy to use but you will be better at using your detector if you take the
time to read this manual carefully and understand what the controls are doing.

CS440XD - Rapid get you going instructions

Assemble and adjust for length. Twist surplus lead around the stem.
Insert battery so that the terminals line up easily with the contacts in the battery compartment.
(9volt MN1604 )

Switch on and rotate Sensitivity Control (14) to the start of the green section on the scale.
Rotate the Discrimination Control (16) to the green position on the scale.
Press the Retune button (15) once.
Start searching using a relaxed motion swinging the search-head from side to side as close to the

ground as possible.
Press the Retune button (15) every few minutes or whenever the background tone rises to an
unacceptable level.
You are now searching in minimal discrimination mode. The presence of a metal target will be
indicated by the increasing intensity of the tone. Signals from small ferrous rubbish will be ignored.

THE CONTROLS AND WHAT THEY DO

(14) The on/o/sensitivity control switches the machine ‘on’ and sets the sensitivity level.

The detector sensitivity should normally be set at the point of threshold, that is the point at
which a background tone is just about audible. The point of threshold will be found within the
green area on the scale. The threshold point should be set with the detector head held just
above the surface of the ground. Switch the detector on, with the retune button (15) pressed.
Rotate the control further until the background tone from the speaker is just audible. This is
known as the point of threshold. Release the retune button (15). The threshold point will be
found on the green area of the scale. In severe ground conditions (wet salt beach or mining
areas for example) it may be necessary to reduce sensitivity to below the point of threshold in
order to achieve stable operation.

(16) Variable Discrimination control. The CS440XD can ignore the signals from some metals
which are likely to be worthless. Small iron objects like building nails are the main source of
false signals, especially on farmland sites. The CS440XD can be set to ignore these signals so
you don’t waste time digging up rubbish. When the Discrimination control is at ‘0’ this is called
‘All-Metal Mode’ and all metals are detected. The ground penetrating capability of the detector
is greatest at this setting. Turn the control to the recommended setting (marked green on
the scale 2 - 5) and signals from small iron objects are ignored but at slightly reduced depth.
Turn the control further (5 - 10) and more classes of metal target are ignored, such as larger
iron pieces and some aluminium based alloys at the top of the scale. However, high levels
of discrimination are not recommended for general detecting purposes, due to the reduced
depth penetration and also because some valuable items (thin section hammered coins and
some rings) may fall into the same category as rubbish and not be detected.

(15) Retune Push-button. The purpose of the Retune push-button is to keep the detector
working at peak performance by maintaining the point of threshold set on the sensitivity
control. For example, moving from dry ground to wet ground may cause the background tone
to gradually increase to an unacceptable level. Pressing the retune button momentarily will
bring the background tone to the point of threshold again.
If the retune button fails to have this eect, it is probably necessary to re-set the sensitivity level.
It is good detecting practice to press the retune button every few minutes or whenever you
feel that that the detector may have drifted away from its sensitivity setting.

Assembly: Join the two stem sections (5)(2) together. Wind the search-head lead (9) around
the stem as shown in the photograph. Adjust the stem for length according to your height (it’s
easier on your back if you can stand up straight while detecting) and tighten the twistlock stem
adjuster (6). Check that the search-head (7) is parallel to the ground when being swept in an arc
and tighten (be careful not to over-tighten) the search-head retaining screw (8). (Keep these
parts clean - if they become covered in mud or sand wash and dry these parts at the end of a
day’s detecting. Don’t allow any form of lubricant onto the rubber friction washers.)

Battery: Push back the retaining clip and remove the cover (13) of the battery compartment
(12). Fit a 9 volt battery (MN1604, PP3 or equivalent). There are guide strips to ensure the
battery is tted the right way round. Do not force the battery. It should slide in easily to connect
with contact strips in the compartment. Remove the battery if the detector is to be stored for
more than a few days.

Searching Technique: Sweep the detector head from side to side in a smooth arc.
Move forward at each sweep the width of the search-head (20cms). Keep the search-head as
close to the ground as possible, even at the ends of the arc where there is a natural tendency
for the search-head to lift. Maintain a strict search pattern so that the area being searched
is completely covered. (You will be more successful if you cover a small area of ground
thoroughly than if you search a large area of ground in random fashion. The CS440XD non­motion electronic system is most suited to a careful detecting technique). When you encounter

CS440MXD_Manual.indd 3 10/5/07 11:09:52

a signal, move the search-head slowly around the area. The signal is strongest when the target
is directly below the centre of the search-head. Remove the clod of earth where the signal
appeared using a sharp digging tool. Check further by passing the search-head over the clod to
see if the target is there or deeper in the hole. Replace the earth after recovery of the object and
it should be dicult to see that the ground has been disturbed.

Do not trespass. Ask permission before searching on private land. Check for local bylaws
about detecting on public land. Not all countries have such a positive attitude towards treasure
hunting as we have in the UK. Observe the Country Code. Fill in all holes. Report all valuable or
historically interesting nds to the appropriate authority. Do not touch any item suspected of
being unexploded munitions - mark its position and report to the police immediately.

Accessories

Contact C.Scope or your local detector supplier for a range of C.Scope accessories.
Headphones: make it easier to hear weak signals and increase battery life. The headphone
socket is underneath the control box (11).
Search-head cover: protect the underside of the search-head from abrasion damage.
Extends the life of the search-head.

Rechargeable batteries. Digging Tools. Detector Bags.

Detector Care

The CS440XD is a robust design. However, the control box should be treated with similar care
as any electronic product. Dry o any water splashes immediately. The search-head may be
immersed in water. Stem and search-head parts should be washed with tap water and dried
at the end of a day’s detecting. Do not use solvents.

Warranty & Service

The CS440XD is guaranteed free of manufacturing defects as conrmed in our written warranty
document. Contact us if you have any concerns about the operation of your detector.
The C.Scope Customer Service Team really know about metal detectors and are always ready
with good advice and rapid after-sales-service.
