Discrimination Menu
The Discrimination Menu allows you to Select, Save, Edit and Combine Discrimination Patterns. Important
Note: ALL Discrimination Patterns Pre-Programmed into E-Trac are 'accepting' Discrimination Patterns e.g.
the Iron Disc Pattern accepts iron.
E-Trac comes pre-loaded with ten (10) Discrimination Patterns which are:
- all metal – coins – Jewellery – foil – pull tabs – crown caps – screw caps – nails – iron – Fe Coins
NB: as E-Trac is a completely new innovative metal detector it allowed the engineers to go back to the
drawing board and bring into line the complete conductive range of all metals in a linear fashion: on the
left are very low conductive, in the middle area mid conductive, and to the right, high conductivities with
the most conductive i.e. copper and silver to the right hand side end of the linear scale. The conductivity
scale has a wider range of IDs (from 1 to 50) and the ferrous range is expanded also (1-35). So on E-Trac,
the Ferrous scale is on a vertical adjustment and the Non-Ferrous or Conductivity scale is on a horizontal
adjustment.
This change is very important to owners of the previous FBS Explorer models as the axes were di erent
i.e. ferrous was the horizontal scale and non ferrous was the vertical scale. But remember, E-Trac is a unique
machine so you can expect new and distinctive features at every level!
Auto Latch (Semi-Automatic Discrimination Editing)
Within the Discrimination Menu, E-Trac has a brand new, very innovative feature called Auto Latch which
provides semi-automatic editing of your Discrimination Pattern. In this editing mode the Edit Frame will
automatically move to the Ferrous (FE) and Conductive (CO) coordinates of the detected target. You can
then choose to accept or reject that target from your Discrimination Pattern using the Accept/Reject
button found on E-Trac's front panel.
The Combine Function
Again, this is a brand new feature which allows you to merge preset or
saved Discrimination Patterns to create a new Discrimination Pattern.
The Combine function should not be confused with how you select
Discrimination Patterns via the 'Select Menu' .
With Combine, you do not add or subtract whole Discrimination Patterns.
The accepted target 'white' areas of a listed Discrimination Pattern are what
you accept or reject from the Combine Discrimination Pattern.
The two Smart nd™ Windows at the top of the Combine Screen are the Combine Pattern (left) and the
active Disc Pattern (right). The Active Pattern is the Discrimination Pattern currently being used in the
Pattern / Digital Screen.
By default, the Combine Pattern (left Smart nd™ window) is empty. As you scroll down the listed
Discrimination patterns, areas of the Combine Pattern will ash relative to the white areas of the selected
Disc Pattern. For example, if you select the Jewellery Disc Pattern, then the white area of that pattern will
ash in the Combine Pattern. Each Pattern that is pre-programmed into E-Trac is, as I stated above, an
accepting i.e. the Jewellery Disc Pattern accepts Jewellery, the iron disc accepts iron etc. Therefore, the
' ashing' area indicates where the object is located.
