Commenting the found target:
In the images below, it defines the SIZE OF THE TARGET
when passing over any metal. It is an estimate of its depth and diameter. (When walking with big
coils)
1-The signal is sudden and short, double voice
2-Short time weak signal
1-The signal is sudden and short, double voice
Those close to the surface will usually show themselves with strong signals that
increase suddenly and end early when they pass over them. When small metals
and shallow targets are detected, the bars will give high but short-term signals.
When the target encounters with the cable under the coil, the strength of the
signal increases. When the target reaches the center of the coil, the signal
strength decreases. When the cable encounters directly under the other pipe, the
signal increases again. These signals indicate that there is a small metal on the
surface. Metals in this signal are generally between 0.50 cm.
2-Short time weak signal
The sound given in this table is not a double sound, but again a signal that ends
very early. Since it is a little deeper than the previous one, it does not give a
double sound. That is, the large coil has difficulty grasping this metal because
the sensing effect is low. It gives a single sound, sometimes it may not even give
a signal when you enter the target from different directions.
These types of metals are generally between 30-70 cm. On average 3-5 cm in
diameter.
