OPERATION OF THE CS1M
Switch unit on by turning Sensitivity control clockwise. Set the control fully
clockwise. If you experience interference from external sources or soil
mineralisation, reduce the sensitivity until the detector is stable. Sweep the
search head from side to side. The presence of metal will be confirmed by a
bleep from the speaker as you pass over the object.
N.B. Before turning on the detector, ensure no metal objects are in the
vicinity.
Discrimination
The CS1M has a variable discrimination control which allows the operator to
choose from any setting between all metal detection to iron and silver paper
rejection.
To adjust the Discriminate Level Control turn Discrimination Level Control to
the desired level.
If an object has been discriminated, the detector will ignore it. For example,
with the control set to 3, an iron nail will be ignored but a coin accepted.
Please note at higher discriminate settings some desirable objects may
be ignored by the detector.
USE OF YOUR DETECTOR IN THE FIELD
Detecting
To test for the type of signal you will get, take a coin or metal object and with
the detector set up on a table, move the metal object across the search head.
You will hear a short bleep as you pass the metal across the search head,
and another bleep as you pass back again.
Detection Range
Detection ranges will vary depending on the size of the object, the length of
time an object ahs been buried, and the type of ground the object is buried in.
The best ground conditions are dry well compacted soils the n coins can be
found at the greatest depths if they have been buried for some time and the
coin has interacted with the salts in the ground, thereby appearing larger to
the detector. The worst conditions for detecting are on loosely compacted or
freshly dug ground or when the object has only recently been buried. In these
conditions detection range will be reduced. 90% of all objects are found within
