TURNING ON THE DEVICE
GROUND BALANCE
To turn on the device, rotate the On/Off knob to ON. Turn the same knob to OFF position
when you want to turn off the device. When the device is turned on, a melody will be heard
and approximately 10 seconds later you will hear a long beep indicating that the device is
ready to use.
The device will provide more depth at on position. However, to better discriminate ferrous
metals, using the device in mineral modes and the iron discrimination at maximum position
is recommended.
Especially in mineralized ground target signal is negatively affected by the ''noise'' caused by
ground mineralization. This situation may prevent the detector from getting a clean signal
from the target necessary for metal detection and accurate discrimination. Ground balancing
is a process through which the metal detector is able to cancel out the negative effects
caused by ground mineralization.
To ground balance, holding the search coil 5cm. above the ground, sweep it right and left,
keeping it parallel to the ground and slowly turn the ground balance knob clockwise until the
noise is gone and the device is silent. If you cannot ground balance the detector, gradually
decrease the sensitivity and repeat the above steps.
