2.2 Sensitivity
Sensitivity is the level of response to a target. The Vista SMART is highly sensitive and has a wide
adjustment range. Although the Vista SMART has an operating frequency of 15,5 kHz for a
smooth and quiet operation, it is very important to set the Sensitivity level correctly according to the
detecting conditions.
A high Sensitivity setting enables the detection of smaller and deeper targets. When the Sensitivity
is set to high, the Vista SMART may be affected by minerals in certain soils and signals from elec-
trical appliances. You may need to decrease the Sensitivity to silence false signals or electrical in-
terference. This will result in a more stable operation of the Vista SMART.
Always choose the highest stable Sensitivity setting to ensure best performance. This is done by
turning the Sensitivity knob to the right until the Vista SMART becomes unstable; then reduce the
Sensitivity by one or two settings until it is stable.
2.3 Ground
The Ground knob is used to adjust the Vista SMART to the soil conditions and correct ground
effects encountered during detecting. Mineralization and “Hot Rocks” may cause false signals.
Ground balancing the Vista SMART reduces false signals from ground mineralization; more
accurately rejects ferrous minerals or pottery containing iron oxides and enables targets to be heard
correctly. If there are “Hot rocks”, these can be elliminated by turning the Ground knob to the
right.
Learning how to properly Ground balance will give you a an advantage over others especially if
they are running there detectors in an auto ground balance mode.
2.4 Discrimination
The Disc. knob is used to eliminate iron objects from detection. The Discrimination has a very fine
adjustability range. The further the knob is turned to the right in the Disc. Mode (also known as the
SILENT DISCRIMINATION
MODE, the trigger on the bottom right side of the control box pulled
towards you), the bigger the size of the iron object will be that is to be discriminated. In the last
third section of the Discrimination scale, small aluminum foil will also be rejected. In the 2 Tone
Mode (trigger on the bottom right side of the control box pushed furthest from you), the Disc. knob
has a different function. It is then used to allow you to adjust the audio level of the low tone for
iron targets.
