Iron Mask - Setting the 
Level of Ferrous Rejection
Range:   All Metal, 0 to 31 
Factory Preset:  22
Iron Mask allows you to change the 
Discrimination Pattern by adjusting 
the level of ferrous rejection. Iron Mask 
can be turned on or off (switching back 
to Smartfind or Digital). The Iron Mask 
screen displays the Discrimination 
Pattern (similar to the Smartfind) and 
a slider control to adjust the level of 
ferrous discrimination. The level of 
ferrous discrimination can be adjusted 
using the shift buttons next to the slider 
control.
To accept more high-ferrous objects 
(e.g. war relics):
Reduce the level of ferrous rejection by 
pressing the bottom left shift button 
next to the slider control. You will notice 
that the number increases because the 
Iron Mask level refers to the horizontal 
ferrous scale ranging from 31 to 0. You 
may need to experiment a little with the 
settings.
To reject more high-ferrous objects:
Set the level of ferrous rejection to 
16. This is represented by the mask 
extending to half way across the 
Smartfind screen (pg. 28).
Once adjusted, you can continue 
detecting in the Iron Mask adjustment 
screen, as accepted targets will still 
appear as a Crosshair in the clear area of 
the window.
Or you can choose to continue 
detecting in Smartfind with Iron Mask 
ON. The Smartfind window will adopt 
the new Iron Mask Pattern.
The 
IRON MASK shortcut button turns 
Iron Mask ON / OFF, switching between 
three screens:
> Iron Mask ON - adjustment screen,
> Iron Mask ON - Smartfind or Digital,
> Smartfind or Digital (Iron Mask OFF).
The Factory Preset of 22 is suitable for 
rejecting most high-ferrous junk targets
