The sound control circuit chooses which signal to send to the speaker at a given
moment:
– when Th Sens is set to 0, the sound from the All metal channel is blocked.
As this parameter is increased, the sensitivity (and also range) of the All metal channel is
increased;
– when the Audio Gain is set to 0, the sound from the Motion channel with objects identification
and Discrimination is blocked. Higher values allow the sound to be passed to the speaker.
In the sound control circuit, the Motion channel with objects identification and
Discrimination has priority over the All metal channel. In this way it is possible to hear the
presence of all the objects (from the All metal channel) and interruptions from the Motion
channel, if an object is accepted by Discrimination.
This design allows the detector to work in several modes of operation:
1. Motion mode with Discrimination – a classical detector.
2. All metal Non-motion – a mode used to search for large objects.
3. All metal Motion („single-filter”) – a mode which allows large objects to be found but with the
ability to separate many small objects on the surface of the ground.
4. 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.
The mode is selected by setting the Th Sens to 0 and Audio Gain above 0. This gives the ability
to set individual sound tones for each ID position or use the preset sound profiles. In this mode
both identification and Discrimination work.
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 30 [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.
NOTE: When searching for coins and other small non-ferrous objects we recommend: Coins
group sound profiles and setting the Discrimination level to above 20 [-30].
