Fig. 5

VDI-number “Visual Discrimination Indication”. This is the index of electrical

conductivity of the object or the angle between the vertical axis and the predominant

direction of the hodograph (time curve). In this case, hodographs which are on the left

side of the screen have a negative VDI, and the right - have a positive VDI number. The

amplitude of the signal, from detected objects, is displayed in standard numerical units

ST SENSITIVITY, RT SENSITIVITY / VOLUME

This section introduces the three main parameters that you'll use most often. For

each of these settings there is an individual button on the control panel.

SENSITIVITY ST [1 .. 14]. Increasing this setting allows you to increase the depth

of targets you're searching for, but it reduces the accuracy of identification and increases

the risk of false positives. The recommended value is 9-10.

Warning! Setting of the ST sensitivity above 11, and especially 14 can lead to

a significant increase in the amount of false positives from the soil in high

salinity or when bumping the search coil.

SENSITIVITY RT [0 .. 9]. Adjusts the sensitivity of the threshold or RT channel

you hear constantly during the search. The value of this parameter is set as a compromise

between sensitivity and comfort. Increasing this value increases sensitivity in the threshold

channel. However this can reduce the comfort in searching. Recommended settings are 6-7.

VOLUME [1 .. 9]. This setting adjusts the overall volume of the audio response

from detected objects. Select the value based upon individual comfort preference. The

current values of these parameters are displayed on the screen above the relative buttons (Fig.

6).
