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.

Smartfind Discrimination pattern

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.
