sensitivity, ground effe & discrimination
You will be able to get more performance out of your detector if you
understand the relationship between three aspects of detector operation
- sensitivity, ground effect and discrimination. If you increase the power of a
metal detector too much the ground itself is detected and false signals make
the detector difficult to use. The 'motion' electronic system of the CS3MX
will ignore many ground effect signals but some types of ground, notably
waterlogged or containing salts or mineralisation require the detector to
operate on reduced sensitivity.
The CS3MX can be set to ignore signals from certain categories of metal target.
Small iron objects in the ground are a problem on many farmland sites. These
signals can be ignored by setting the discriminate control to about number
'2', within the green area on the discriminate scale. As the control is turned
clockwise the signals from more types of metal likely to be worthless can be
