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.

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.
