Most fine white gold rings, foil,
and some yellow gold rings will
also be ignored. With experience,
setting the Disc control to ignore
most unwanted targets (in
combination with the Notch
control) will become second nature.

Notch Control
Located on the center left of the control panel, the
Notch control is used in combination with the Disc
control to discriminate against, or ignore, certain
metal objects. As with the Disc control, it is
continuously variable and features numerous
graduations as a guide to setting the control.
The main difference between the Notch and Discrimination controls is
that Discrimination is a continuous band of discrimination, whereas the
Notch is in fact a short segment of discrimination which can be moved up
or down the scale of conductivity.
As the Notch control is turned further clockwise, objects of a certain
conductivity will be ignored. Turning the Notch control to ignore the
pull-tab will mean that only non-ferrous objects having a similar
conductivity to the pull-tab will be ignored while all other non-ferrous
objects of a different conductivity are still accepted. Note also in
Figure 16 that ferrous objects are being ignored due to the Disc. setting.
