Depending on the soil concerning the searcing depth it is not possible to give a state-
ment. The settings of the searching memorie will not be stored in memory. So it al-
ways has to be set individuelly. The factory setting is a good average value for 28 cm
– 50 cm coils.

Audioverstärker / Audio Amplifier:
The audio amplifier multipies the click rate of the tone generater by its value. The
maximum value is 16. If you have a signal with 10 clicks per second the click rate will
be multiplied to 160 when amplifying by maximum. Accordingly the rasing speed of
the audio signal and its sensitivity is rising.

Diskriminator / Discriminator:
The discriminator has a range of 1-5. Because of the high sensitivity of the detector it
is not possible to distinguish smallest and biggest objects in the same matter. The
discriminator is based on an algorithem for alloys. It equals a balance weigher. The
possibility of discrimination is based on the characteristics of the metals. Deciding are
its conductivity, shape, alloy, position and distance. Furthermore die type of soil is
important. The electromagnetic field may be influenced. Also there is an enormous
amount of soil behind the detected object which also will be detected and measured.
Very often a bigger distance to the ground or tipping up of the coil can help. The post
important parameter is that the detection for a defined identification has to be repro-
duceable. The sum of different characteristics of different objects may produce a
similar sinal to gold. If you imagine how many unknown characteristics have to be
considered that is not astonishing. Therefore tests with different objects and metals
are necessary. Bigger or massive non ferrous metals will always show a negative
result in the air if they are not “alloyed”. Even if pur gold will be “alloyed” in the soil by
salts cristals or smallest objects.
In setting 1 the discriminator has the strongest filter. A golden ring (333, 485) will be
detected very sure. After start the discriminator setting is 2. The spectrum is working
independent of the discriminator setting and can help when testing and finding set-
tings.
