STRUCRURE AND
OPERATION
- Switch ,,AUDIO DISC” - turns on
and off audio discrimination;
- Pot ,,THRESHOLD” - used for
adjusting sound level and regulates
depth of searching;
- Pot ,,GROUND BALANCE” -
eliminates influence of the soil;
- Pot ,,DISC LEVEL” - regulates
degree of elimination of iron
metals;
- Pot ,,VOLUME” - switches on
the detector and adjusts sound
level;
- Pot ,,SENS” – used for additional
regulation of depth of mineralized
regions;
- Jack ,,HEADPHONES” –used for
headphones;
- Light indicator
“LOWBATTERY” – indicates
lower tension of batteries.
The detector turns on with the help
of the potentiometer /pot/
,,VOLUME” which also regulates
sound level.
*Adjusting the settings
Set the pot ,,THRESHOLD” in a
position that a light “buzz” can be
heard of the detector. Set the
switches ,,AUDIO DISC” and
,,VCO” on ,,OFF” position, so the
search coil starts to move vertically
towards earth surface /up and down:
from 3cm to 20-25сm over ground
surface/ /fig.1/ and the pot
,,GROUND” turns around slowly.
fig.1
Sound increases when the coil
reaches the ground; and when the
coil moves away the ground, the
pot is turning around while the
sound doesn’t change any more or it
changes very slowly. While
balancing the detector, you have to
be sure there are no metal objects
around!
Separating metals is with the help
of two types of sound
discrimination:
1. Using audio discrimination:
- Set the switch ,,VCO” in a
position ,,OFF” and ,,AUDIO
DISC” in a position ,,NORM” or
,,FULL” /for full elimination of
ferrous metals/, set the pot ,,DISC
LEVEL” in a position 3. If you
