Introducing Discrim
Discrim (an abbreviation of Discrimination) instructs the detector to
accept some types of targets and reject others. It uses Smartfind's
two-dimensional discrimination, allowing you to specify one or more
target patterns for detection.

Figure 5.4
When you begin in Quickstart, you will see a Smartfind display
resembling Figure 5.4. This display shows that the detector is
ready to operate in its preset Coins Discrim function.
The discrimination pattern represents the typical characteristics of
non-ferrous coins (actually a composite of hundreds of coins from
around the world). When the search coil passes over an object
matching the conductive and ferrous characteristics of coins, the
target crosshair will appear in the clear area and a target response
will sound. Objects outside of the accepted (clear) area are not
displayed and the threshold 'hum' is temporarily silenced. The target
crosshair will remain locked in the position of the last accepted target.
The discrimination pattern 'maps' the specific ferrous and conductive
properties of coins, providing excellent accuracy in detection of this
particular type of target.
NOTE Quickstart offers a range of discrimination patterns
which may be used on their own or in combination. This is
detailed in Selecting Targets, page 62.
