where a background tone is just starting to become apparent. Some detector users prefer to set
sensitivity at a lower level than this so that there is no background tone. (sometimes referred to as
‘silent search mode’).
3) Loudspeaker
(and battery condition indicator). The presence of metal is indicated by the
increasing intensity of the loudspeaker tone, accompanied by the LED which illuminates.
4) LED
gives visual confirmation of the audio signal.
5) Pulse frequency selector
(and battery check position). This control is calibrated in the frequency
of the detection signal (pulses per second). The recommended setting is within the green zone on the
scale. (A metal detector is a type of radio receiver in its principle of operation and may be subject to
interference from, for example, overhead power lines, transmission masts and even other detector
users in the near vicinity. The pulse frequency control gives the possibility to change the operating
frequency to an area free of such interference). Other pulse frequency settings, within the red zone on
the scale, can be used in treasure hunting applications but they tend to be insensitive to thin section
non ferrous objects. As many valuable objects fall into this category, we do not recommend the use of
these frequency settings. When the battery check switch position is selected (red battery symbol), the
detector will emit an audio tone proportional in length to the condition of the batteries. A tone of 1
- 2 seconds duration indicates good batteries. No tone indicates that the batteries should be changed.
T
he stem height adjuster should be
slackened to allow the lower stem to
enter the upper stem section. The
search-head lead may then be wound
around the stem as shown in the
photograph. A search-head lead which is
not well secured to the stem could move
about causing false signals. Cable ties
or tape may be used to hold the lead in
position.
When the search-head lead is fitted
correctly, the stem adjusting device can be tightened at a height suitable for the user. Adjust the
position of the search-head so that it is parallel to the ground when the user is in a normal standing
position. Tighten the wing-nut on the search-head retaining screw. Do not over-tighten.
Friction of the head lugs against the neoprene washers keeps the search-head in position.
Excessive pressure on these parts should not be necessary. (If some form of lubricant should ever find
its way onto these washers it will be necessary to disassemble the parts, wash and dry them before
careful reassembly).

Control box mounting clip.
For ultimate lightweight metal detecting the CS4PI control box can
be removed and fitted to a belt around the body. This leaves only the search-head on the stem which
reduces fatigue on the arm.
2) On/off/sensitivity.
Rotary control switches the detector on/off and adjusts the sensitivity.
The area on the scale around the control marked in green is the setting recommended for most
ground target characteristics. The CS4PI is at its most sensitive with sensitivity adjusted to the point
