Scanning Techniques

8.1

Super Sensor

The Super Sensor is a high resolution antenna, which is specially adjusted to detect metals. Yet it is also

possible to recognize larger voids with this antenna. A particular
characteristic is to distinguish ferrous metals from non-ferrous

metals. This discrimination is possible in the operating mode Pin
Pointer. Compared to the Telescopic Probe the Super Sensor can

find much smaller and deeper situated metal objects.

The Super Sensor can be used in the following operating modes:

•

Ground Scan

•

Pin Pointer

•

Magnetometer

•

Mineral Scan

To use the Super Sensor with eXp 6000, simply connect it to the
telescopic rod assembly and always hold the antenna vertical to

the ground. Figure 8.1 shows how the Super Sensor has to be
held correctly.

The Super Sensor should not be swung nor change height, either
up or down, during the measurement. The smoother the antenna

is held, the better your scan results will be. The distance
between the ground and lower part of the antenna should be

about 10 cm, but can be enlarged depending on the terrain
conditions.

The eXp 6000 control unit will assist you by indicating the proper orientation of the Super Sensor at all
times during a scan. This behavior is explained in section 7.3.1 “Orientation of the probe” on page 77.

The orientation of the antenna should not be changed during the complete measurement!
