3.2 Search process (measurements)
The GPA is a measuring device, which can measure alterations of ground anomalies
caused by metal objects, soil structure or excavations and can discriminate from
normal ground magnetism. Correct results strongly depend on ground type and
measuring method. Areas to be measured should not have electric fields (like high
voltage cables or earth wires) or strong mineralising or wet grounds, because they
influence the measurement. The dryer the soil, the more precise the results.
Split the area you want to measure into even tracks. You may choose between 2
methods:
3.2.1 Search in one direction
If you have chosen the search in rectification, you should return to the starting point
after completion of each track and press the start button (for measurements of the
second track).
