9.6. GROUND FINELY potentiometer
The GROUND FINELY potentiometer serves as a further fine (precise) setting
of the ground balance in a manual ground balance working mode, ie for a fine
and complete eliminate of the ground effect at work in a manual ground
balance working mode.
The GROUND FINELY potentiometer is used in combination with GROUND
COARSE potentiometer.
The recommended level for GROUND FINELY potentiometer is level "5". This
allows, if required, through it to be made easy adjustment of the ground
balance, by turning it on the left (levels from "4" to "-") or on the right (levels
from "6" to "+").
GROUND FINELY potentiometer is used for adjustment of an already set at base level by GROUND
COARSE potentiometer, ground balance, in manual ground balance mode.
Additional information on the process of balancing in manual ground balance mode has in the
description of a GROUND COARSE potentiometer available above.
In practice, in a manual ground balance mode, the most commonly used settings are:
Setting for medium mineralized terrain in GAIN = MAX, GROUND MODE = MAN:
- For v2: GROUND FINELY = "5", GROUND RUDELY = "6";
- For v2i: GROUND FINELY = "5", GROUND RUDELY = "5";
- For v3: GROUND FINELY = "5", GROUND RUDELY = "4".
Setting for high mineralized terrain in GAIN = MAX, GROUND MODE = MAN:
- For v2: GROUND FINELY = "5", GROUND RUDELY = "8";
- For v2i: GROUND FINELY = "5", GROUND RUDELY = "7";
- For v3: GROUND FINELY = "5", GROUND RUDELY = "6".
In this mode (setting for high mineralized terrain) easily be rejected also very rotten (decomposed)
small iron plates, pieces of tin cans and other heavily corroded irons, and of course, objects and
soils with high content of iron and iron oxides.
9.7. THRESHOLD potentiometer
The THRESHOLD potentiometer serves to define the desired from the user
audio threshold and sensitivity of the metal detector.
It is adjusted at absence of metal objects around the search coil of the
metal detector and depends on the terrain.
The recommended levels for THRESHOLD potentiometer are from level "4" to
about level "6".
The best depth for finding metal objects is achieved, when the THRESHOLD
potentiometer is turned in a position, corresponding to a quiet zoom sound
made by the metal detector in working mode (issued torn sound, buzzing,
whiz).
Quiet zoom sound mode is suitable for experienced seekers. The beginners should work at lower
levels, i.e. with completely silent (quiet) metal detector.
When working in manual ground balance mode, is necessary the final audio threshold level to
be set only after the metal detector is balanced.
The maximal audio threshold corresponding to a stable metal detector condition depends on
the terrain’s characteristics, the metal detector balancing (in manual ground balance mode)
and the user search speed.
For soils containing large amounts of salts, in moist and wet soils, in clay soils, when searching
on the beach and searching in salt water, is recommended potentiometer THRESHOLD to be
set at lower levels (from "5" to "3").
