17. Rejection of hot rocks from metal detector

BLISSTOOL LTC64X (THE BEAST)

Metal detector BLISSTOOL LTC64X (THE BEAST) is designed to be effective on all types of

terrains, including medium and highly mineralized terrains, terrains with a high content of ore

and terrains dotted with stones and rocks, slag, hot rocks and ceramics.

In all versions of THE BEAST, for effective rejection of hot rocks, is recommended:

- work in manual ground balance mode (GROUND MODE = MAN) and manual ground balancing

of the metal detector (with potentiometers GROUND COARSE and GROUND FINE), not to the

ground, but directly on a piece of hot rock (placed on the ground) up to its rejection.

The same method is applied and for manual ground balancing to ceramics, stones and rocks.

- work in automatic ground balance mode (GROUND MODE = AUTO), AUTO ZONES = III.

For hot rocks, containing ferrous metals and their oxides (for example: iron and iron

oxides), the manual ground balance is done in mode "All metal", i.e. with off discrimination of

the metal detector (DISCR LEVEL = 0, DISCR DEPTH = 0). After the manual ground balancing

on the hot rock, are set the user-selected levels of discrimination (for example: DISCR LEVEL

= 4 - 5, DISCR DEPTH = 8.5 - 9.0).

For hot rocks containing non-ferrous metals and their oxides, because of their

presence, usually manual ground balance in mode "All metal", i.e. with off discrimination of the

metal detector (DISCR LEVEL = 0, DISCR DEPTH = 0) is not possible. In this case, the manual

ground balance is performed with prior set discrimination of the metal detector (for example:

DISCR LEVEL = 4 - 5, DISCR DEPTH = 8.5 - 9.0).

In most cases, the setting for rejection of hot rocks, coincides with the setting for

ground balance to ferrite and with the setting for work on highly mineralized

terrains.
