resistant to external electromagnetic interferences.

When working in a manual ground balance mode (switch GROUND MODE = MAN), if changing

the setting of potentiometer FREQUENCY, is necessary a new manual setting of the ground

balance via potentiometers GROUND COARSE and GROUND FINE. It is necessary to increase

the level, as typically, the offset is with maximum 1 - 1.5 - 2 levels. For example, if with a

setting FREQUENCY = MAX, the metal detector is balanced to the ground at GROUND COARSE

= 5.0 and GROUND FINE = 5.0, follows that with a setting FREQUENCY = MIN, for the same

terrain, the metal detector will have balance to the ground at GROUND COARSE = about 6.5

and GROUND FINE = 5.0. For low mineralized terrains, this difference is usually negligible, but

for medium and highly mineralized terrains, it is significant and should be considered.

The TURBO/BOOST mode of v4 and v5, is effective not only at low mineralized

terrains, but also in medium and highly mineralized terrains, terrains with a high

content of ore and terrains dotted with stones and rocks. However, due to the increased

transmitted power in TURBO/BOOST mode, in medium and highly mineralized terrains, terrains

with a high content of ore and terrains dotted with stones and rocks, the manual ground

balance may be more difficult to achieve, than in mode NORMAL. In such terrains, the manual

ground balance in mode TURBO/BOOST, is still relatively easily attainable, but the setting

should be done more carefully and more precisely by the user. For this purpose, after the basic

setup of the ground balance from potentiometer GROUND COARSE, is very convenient the use

of a potentiometer GROUND FINE for additional, fine tuning.

In some terrains, for example in highly mineralized terrains, terrains with a high content of ore

and terrains dotted with stones and rocks, and especially in heavy specific field conditions, the

TURBO/BOOST mode instead providing of a greater depth of detection, may have the opposite

effect. Therefore, in v4 and v5 are available for selection by the user the two modes: mode

NORMAL and mode TURBO/BOOST. It provides an opportunity for excellent depth of detection

in all field conditions.

11.2. ADDITION about potentiometer FREQUENCY of v4 and v5

With setting FREQUENCY = MAX, v4 and v5 work with base operating frequency

8.0KHz and NORMAL mode of the transmitter.

With setting FFREQUENCY = MIN, v4 and v5 work with base operating frequency

7.4KHz and TURBO/BOOST mode of the transmitter.

Mode TURBO/BOOST is designed to be used as a search mode in itself, similar of the

mode NORMAL. Not recommended switching between the two modes (NORMAL and

TURBO/BOOST), in order to further examination of the detected metal object, because in a

manual ground balance mode (GROUND MODE = MAN), the switching between the two modes,

requires a new setting of the ground balance of the metal detector. The difference in the

ground balance, is particularly noticeable at high levels of GAIN, and also at medium and

highly mineralized terrains, terrains with a high content of ore and terrains dotted with stones

and rocks. Therefore, switching between the two modes (NORMAL and TURBO/BOOST), in

order to further examination of the detected metal object, is only effective at low mineralized

terrains and when working with low levels of GAIN (GAIN = from MIN to 3).

Moreover, unlike other brands of metal detectors, the TURBO/BOOST mode of THE BEAST

is designed to be completely stable and universal, like the mode NORMAL. However,

due to the increased transmitted power of the transmitter, mode TURBO/BOOST is not

recommended in damp and wet soils, as for such field conditions, mode NORMAL is most

suitable.

Because of the different transmitted power in mode NORMAL and in mode

TURBO/BOOST of the transmitter:

- with a single charge of the LiPo battery, v1, v2 and v2i can work up to about 35 - 40 working
