How to Ground Balance
The following steps will explain how to Ground Balance the Vista MINI. This is a very simple
process that allows you to balance the Vista MINI to all types of soil. This is very important in
order to obtain maximum sensitivity to small targets and depth.
Turn on the Vista MINI with the Power Switch
Set the Sensitivity as described in section 2.2
Controls/Sensitivity
Switch the three Position Trigger Switch to the ALL Position
Find an area free of metal targets
Push and hold the three position mode switch to the GRD Positioin
Lower the coil about 2 cm (1 inch) above the ground
Raise the coil up about 15 cm ( 6 inches)
Repeat this process until no or very little noise is heard as you lower and raise the coil
Your Vista MINI is now Ground Balanced. If the soil conditions change significantly (by moving
from a plowed field into a wooded area for instance), you must ground balance your Vista MINI
again as described above.
If you receive false signals from iron oxides in pottery or “Hot Rocks”, you can then Ground
Balance the Vista MINI directly over these objects to eliminate signals from these unwanted targets.
