Adjust the volume of the low-pitched tone which has a lower value than the discrimina-
tion setting, which normally means iron.
0 = cut-off low tones 10 = maximum low tone level
You can also adjust this tone 1 volume in the Multi-tone screen (EXPERT menu of 2-3-4-5
tones and Full Tones)
Iron volume
is a fast and selective detector! Reactivity is a vital setting that determines
the detector’s performance in terms of how quickly it analyzes the signal from detect-
ed objects and its ability to separate the signal response from two or several targets
located close together. This is also known as Recovery speed. If the soil contains a
great deal of iron, hot rocks or other mineralized debris, soil penetration can be dras-
tically reduced as can the ability of a detector to locate non-ferrous targets next to
ferrous targets. In these conditions, select a high degree of reactivity which will help
to speed up the signal analysis. On the other hand, if the ground is "clean", it is better to
reduce the Reactivity, to make the machine more sensitive to deep targets.
Reactivity
On a beach, as the targets are most often well away from each other, the low Reactivity levels like 0 or 1
will be very efficient. But if you encounter tricky conditions, such as polluted beaches made up of mag-
netic black sand or beaches with variable salinity, increase the Reactivity to 2.5 or 3, thereby becoming
more selective and more stable, which will make it far easier for you to interpret the targets.

Small coins with low conductivity and fine jewellery, gold nuggets on highly mineralized ground. Discrim-
inates (distinguishes) coke more easily with a precise target identification (~25). More unstable on wet
ground, non-magnetic.
General use, small coins. Coins of all sizes in moderately to highly mineralized ground.
Large, mainly ferrous and non-ferrous masses, coins grouped together or high conductivity coins.
General use. Coins and large masses, militaria. Medium and small targets in low-mineralized ground.
