items or under active stones and highly mineralized soils.

In this case, if, for example, an object (stone, ceramics or some iron) has been memorized,

with own signal of „-28“, the device will not react to any signals smaller than „-28“, and

each signal greater than „-28“ will be registered with sound, as the objects „with more

positive signal― (from „-27― to „0“) will be signalized with a low tone, and all positive

ones – with high tone. If from the menu for „Low tone“ a value of „1“ has been selected,

for the negative signals there will not be low tone and the device will react with high tone

only for the positive signals, i. e., for the nonferrous metals.

Analogue is the operation of the device also when working in an „auto discr +“

mode – all metals with a signal more positive than the memorized one will be signalized,

and all having values lower than the memorized, will be eliminated.

The difference between the„auto discr +“ and “AUTO DISCR +“ modes is that at a

selected mode with capital letters the device operates more effectively for bigger objects

and can successfully memorize and eliminate undesired bigger objects or more active soils

(in „REJECT“ mode). When operating in „auto discr +“ / „reject“ mode, the device can

successfully memorize and eliminate undesired smaller objects – for example wire and

small nails, and to effectively search for coins, rings or other small objects, but in this

mode very big objects or very high mineralization of soil can provoke undesired misleading

signal. In such cases it is recommended the device to operate in „AUTO DISCR +“ mode.

The modes with „+“ can be selected by pressing the button „SELECT“ until the

„discr“ parameter appears, and one has to choose either „discr 3“ for „auto discr +― or

„discr 4“„AUTO DISCR +“.

Switching between the modes with „+“ and without „+“ can be done also during

work with pressing and holding of the buttonh „VCO / DISCR“ for more than 3 sec., but

this can be done only in the sub – modes „reject / REJECT“.

3. Balancing to the background of the soil in the discrimination modes.

Usually, „light― weak mineralized soils have their own signal of up to „Level: 15 –

20“. On them, one can work in a "NORMAL DISCR" mode, and the only balancing which can
