MODE 1: SEARCH AND CAVITY DETECTION
After the effect is completely removed, press the OK button as the coil is lowered
down to 10 cm. Now switch to the search mode and start searching.

Hold the coil at a distance of 10 cm from the ground. Be sure that the coil is paral-
lel to the ground. Sweep the coil with slow motions from left to right for accurate
target detection.
Be sure that you keep your search coil within 3-40 cm at all times. This will mainta-
in the proper Ground Balance. If you exceed these limits, you will receive false
signals.

The device will produce an audio signal when it
detects metal or a cavity. A signal will be produ-
ced from the following items: CAVITIES, METAL,
FERROUS or PRECIOUS bars. The effect of the
target can be monitored consecutively on the
graph (Oscilloscope) located above these bars.
In this graph, an ascending graph would be
obtained for metal targets and a descending
one for targets like cavities or voids.

In the case that the ground effect cannot be removed, reduce Sensitivity Level by
1 increment and repeat the above process.
