Conducting a measurement 33
• The distance between two scan points must match the object's dimensions. This means you can
only detect underground anomalies if you scan right on top of the hidden targets as well as the
surrounding ground.
• Additionally it will be a good idea to observe the present vegetation since special plants can
indicate the presence of underground water deposits. There also might be areas with more
plants or greener plants than others.
6.2 General Measurement Procedure
Before starting any measurement you have to divide your scan field into single scan points. You have to
choose a consistent distance (resolution) between your scan points according to your preferred
accuracy. You can decide to use 3 or 5 scan points for a measurement with GeoSeeker Mini. Later,
during your measurement, you will collect measure values at each of those scan points from certain
depths.
It is a good practice to mark each of that scan points with some kind of marker (flag, stick, color point,
stone, etc.) to speed up the final measurement. So you have to measure the distances between the scan
points only once during the preparation of your scan field and you can move your equipment from point
to point easily afterwards.
In figure 6.2 you can see an exemplary scan field with 3 scan points. The distance between the scan
points is all the same and can vary from one measurement to another.
At each of this marked scan points, electrical power is injected into the ground using the two Power
Electrodes (electrodes with red socket) and the resulting voltage is measured with the two Voltage
Electrodes (electrodes with black socket). By increasing (or decreasing) the distance of the Power
Electrodes step by step the measure depth also increases (or decreases) accordingly, as shown in figure
6.3.
