of Iron Mask will reject more ferrous targets while a reduced level will accept more
ferrous targets - ideal for relic hunting.
Some improved Iron Mask functions have been implemented:
1. The new Iron mask has values in 0 - 31 range to match the range of Ferrous
numbers.
2. The Iron mask screen has been modified to show "FER" inside the slider and to
show "AM" when the All Metal is enabled.
In Figure 1 (below) the new numbered Iron mask is seen while the old system is
shown directly beneath it.
All Metal
- is the term used to describe a clear discrimination pattern - that is
accepting ALL targets whether ferrous or non-ferrous. To select All Metal press the
shift button next to the AM icon to reduce Iron Mask and clear the discrimination
pattern. Bear in mind that A.M. might be "noisy" on certain soils that might have
high levels of mineralization in them.
Gain
- the Factory preset has been changed to 8, a higher setting from which it
used to be set at in both former Explorer models (used to be 5). This might become
noticeable right away as certain signals might be more pronounced with better,
faster, louder and sharper signals when compared to an older Explorer ll model.
Gain actually controls the amplification of target responses in respect to the
strength of the original signal. The theory is, with a high setting (8) even weak
target responses will initially be, easier to hear which could equate to more finds,
especially small low-conductive ones at the end of a day's detecting or increased
deeper finds from sites considered to be "worked out". On a modern site such as a
concert field looking for recent losses one could use a lower Gain setting coupled
