In Multi-Tone mode the signal tones vary depending upon the object
found. The pitch of signal depends upon conductivity, the higher the
conductivity, the higher the pitch.
Iron has a very special signature that can be recognised easily. We have
assigned it a low-pitched sound together with a volume setting (
IRON
LEVEL
) so that you can make the low tone more or less conspicuous. (This
is assigned to iron and coke).
This operating mode allows for improved analysis and understanding of
the detected area, e.g. in order to find areas of former human
habitation. It also facilitates recognition of large ferrous objects (such as
old weapons). Everybody will find a use for it.
On certain types of ground, especially those contaminated by copper shot
gun cartridges or little pieces of aluminum foil,
GMAXX II
will can signal
the presence of debris by means of
a medium-pitched tone
, whereas as
decent targets
will trigger a
high-pitched sound
. It is up to the user to
decide whether or not to dig, depending on how promising the area is,
the type of target he or she is looking for and the density of rubbish,
since certain small "decent" targets, such as very small coins, may also
trigger a medium sound.
