Under certain conditions, and depending on the ground balance, the detector may react
to non-metallic objects. Hot rocks and other objects which have properties which are not similar
to soil, may create a sound signal. An experienced user will have no problem differentiating
these signals from normal signals as they have very different characteristics. The only way to
identify the conductivity of these metals is to check the ID readouts on the display. The All metal
Motion mode has greater range than the Motion mode with Discrimination.
NOTE: When listening to deeply placed objects it is a common mistake to swing the search coil
too quickly over an object. After the search coil passes over an object and emits a sound, the
Threshold will be turned down. To confirm an object has been located it is important to wait for
the Threshold to return to its original level. This time can be shortened by resetting the All metal
channel using the trigger.
4. Dual mode
This mode combines the Motion mode with Discrimination and the All metal mode. It is
done by setting both the Th Sens and Audio Gain above 0. This combination provides the
advantages of both modes – identification coming from the Motion channel and the maximum
range of the All metal channel. To better understand the characteristics of the Dual mode it is
best to get to know all of the other modes first before starting to use this mode.
When beginning to decide which mode to use for searching, it is best to follow a few
simple rules. These are only initial rules as those with a little more experience will be able to
select the most appropriate for particular situations and object types.
Typical use of operation modes Incorrect use of operation modes
To search for small objects in fields, the optimal
modes will be the Motion ones (with Discrimination
and All metal). The correct mode will depend on the
user’s expectations, if the user wants to search only
for clear signals from non-ferrous metal objects,
Motion with Discrimination is best. If the user wishes
to find all kinds of small objects, All metal Motion
mode will be better. Motion mode with Discrimination
(especially for Reaction set above 2) will
not give good results when searching for
very large, deeply located objects or to
conduct search in places where the
movement of the search coil is
impossible e.g. very dense bushes, or
holes.
To search for large objects at depth, the Non-motion
mode is the best. Non-motion mode will be very poor
when searching for small objects in
highly littered area.
For universal searches the Dual mode will be the
best.
As your knowledge of the particular characteristics of this detector increases it will
become easier to choose the best mode for each terrain and searching task.
