display the Iron Mask adjustment screen.
Preset Level
The Explorer II's Iron Mask is set at a rating of -6. This is suitable
when detecting non-ferrous metals.
Detecting more ferrous objects
If you want target responses from more ferrous objects (e.g. war
relics) it is necessary to reduce the level of ferrous rejection. This
is done by pressing the bottom left shift button next to the slider
control, reducing the extent of the Iron Mask. You may need to
experiment a little with the settings.
Detecting all ferrous objects
If you wanted to detect all objects, regardless of ferrous content,
ferrous rejection can be reduced to a minimum level of -16. The
screen will be completely clear and all objects will sound a target
response.
Rejecting all ferrous objects
If you want target responses to be suppressed for all ferrous
objects, the Iron Mask may be increased to a level of 0. This is
represented by the mask extending to half way across the
Smartfind screen (as depicted in the section explaining
two-dimensional discrimination, see page 42).
Figure 5.5 Adjusting the Iron Mask
The Iron Mask shortcut button on
the control panel allows you to
switch between Iron Mask and
Discrimination.
Before you experiment with this,
an understanding of the features
of these functions will greatly
assist in deciding which will
locate the kind of targets you want
and how to adjust the Explorer II
to suit your preferences.
The tutorials featured later in this
chapter also assume a basic
understanding of Iron Mask and
Discrimination functions.
