This design allows the detector to work in three modes of operation:
1. Motion mode with discrimination – a classical detector.
2. All metal Non-motion mode with different speeds – a mode used to search for large objects.
3. Dual mode – Motion mode with discrimi All metal with any speed setting.
An important part of operating the detector is to understand the characteristics of the
basic modes of operation.
1. Motion mode with discrimination
In this mode the movement of the search coil relative to the metal object is necessary,
both identification and discrimination work in this mode.
Discrimination
This is the ability to block sound signals for objects with conductivity (ID) lower than the
set value. The discrimination scale starts with iron and goes through foil, gold and ends with
silver. A discrimination level set to 0 allows searches without detecting ferrous objects. Naturally,
there will be times when the detector will signal the presence of large ferrous objects as „non-
ferrous” objects. It is generally recognized that discrimination works best for small objects at
shallow depths.
Notch
This type of discrimination allows for selective operation – the user can choose which
types of objects will be indicated and which will not be.
Identification
This function is described on page 6. In practice it allows for the non-standard use of the
motion operation – by setting the discrimination to -90 and not using Notch. The detector will
use sound to signal all metal objects, on the basis of the sound and the indications on the
display, the user will be able to recognize all the objects in the soil. In this way the user is aware
of the conditions in which they are performing the search. If using discrimination in the Motion
mode, they may not have a full view of the situation and would not be aware of how many metal
objects are littering an area.
2. All metal Non-motion
The All metal channel has a variable speed and, depending on the SAT setting, we can
have a fully non-motion (SAT = 0) or fully motion (SAT = 20) working detector.
Fully Non-Motion mode
This operating mode doesn’t need the search coil to be moved to create a sound signal.
It works when SAT are set to 0. The detector signals all metal objects using the sound channel.
The volume and the tone of the sound, depends on the signal’s strength – this gives the user
information about the object’s size and distance from the search coil.
