TUNING OF THE INSTRUMENT
After the user has become familiar with the operation of the instrument, tune it to make it
more selective with the identification of various types of objects.
Discrimination is the ability of the instrument to differentiate between various types of
metals. The settings for the
DISCRIMINATION
function determine whether the instrument
differentiates between ferrous and non-ferrous metals.
This function can be set from the minimum (DISC knob rotated fully anti-clockwise) to the
maximum (DISC knob rotated fully clockwise) or any intermediate position.
It is recommended to use the instrument with the discriminator set to the 3
rd
point
from the left in clockwise rotation, in such way both gold and tin are seen as non
ferrous materials. In case of further rotation of the discrimination dial these
materials will pass on red.
Turning the dial clockwise from the minimum setting the metal detector will discriminate the
non ferrous metals following the table below.

NON FERROUS MATERIALS THAT DEPENDS ON THE DISCRIMINATOR
RED
Gold

BLUE
MAX Clockwise rotation of the discrimination dial. MIN
The metals that depend on the discriminator will be discriminated as you turn the dial in a
clockwise direction. These materials will change from the blue visualization to the red
visualization as the dial is rotated in a clockwise direction.
When a metal under discrimination is found, the needle will move towards the left and the red
LED will light up.
When a non-discriminated metal is detected, the needle will move towards the right and the
blue LED will light up.
