search! Movement should be as smooth as possible, In the fast movements of the search coil
(fig.3) is located on easy surface metals, slow movements are suitable for quick search of
deep buried metal objects.

The exact location of the metal is made with the movement of searching coil in two
perpendicular axes (Fig. 5).

Separation of metals takes place through two sound discriminators.
1. Operating with audio discriminator.
- The key,, VCO DISC "is placed in position,, OFF" and,, AUDIO DISC "in the heading,,
NORM" or,, FULL " (for better discrimination of deeply buried iron objects), Potentiometer,,
DISC LEVEL''in position 4. In the greater number of,, DISC LEVEL''the separation of metal
is better! If you want to discriminate against most non-ferrous metals on the surface (modern
pollutants), the situation of Potentiometer must be over 7. In case of non-ferrous metals (gold,
silver, copper, bronze) resonant sound is heard, and in the presence of black metal (iron) is
heard tear or pop sound.
2. Operating with,, VCO "discriminator.
- the key,, VCO DISC "is placed in position,, ON", a,, AUDIO DISC "in position,, OFF'',
Potentiometer,, DISC LEVEL''in position 4. If you want to discriminate most of the non-
ferrous metal on the surface (modern pollutants) Potentiometer position should be above 7.
In case of non-ferrous metals (gold, silver, copper, bronze)high-tone is heard, and in the
presence of black metal (iron) is heard a low tone.
