38 Operating modes
6.1 Ground Scan
This operating mode allows you to do a measurement with a graphical representation whereby all
measured values will be stored in the internal memory of the device. Also you have the possibility to
recall and see previously stored graphics. This mode can be used with all probes.
The Ground Scan mode is your primary function. This is the mode where you are going to find the
targets and locate areas of disturbed soils. When something is buried, then whoever buried it had to dig
a hole. Look for that disturbance in the soil first. If a hole was created at 1.5 m (4 ½ feet) deep, after a
couple of seasons the hole will appear to be over 2 m (6 ft) in diameter at the surface. Start with a scan
that has an impulse approximately every 30 – 60 cm (1 foot to 2 feet) forward and to the sides (distance
between two single scan lines). Don't go too fine on the first scans until you have a possible anomaly.
Look for the holes! Usually without a hole you could be looking at mineralization.
In figure 6.2 the complete workflow of a ground scan is illustrated. The blue lines are indicating
additional steps that are only processed when utilizing the LiveStream Sensor.
After activating this operating mode you have the possibility to adjust certain settings. There are
different parameters which influence the measurement. You can modify the following parameters (the
underlined values correspond to the setting made by the factory):
