42 Operating modes
6.2 Pin Pointer
This operating mode is used to identify and give the location of buried treasures, metals and cavities.
Therefore it is necessary to connect the Super Sensor. If you don't have the Super Sensor, contemplate
very seriously on acquiring one. This is an extremely powerful and functional antenna that can assist you
in verifying real targets. There are three basic modes in which you will use this function: pin pointing an
object, discrimination of metals, tunnel recognition and then also estimating the size of the object. The
function can also be used over freshwater from a boat.
In this mode there is no given manner or direction you must maintain. You can walk as you wish in every
direction. It is still important that the antenna must always remain in the same direction. This operating
mode is most effective after you have already detected a possible object and now want to know more
details about it.
The Super Sensor should point vertically towards the ground. It should not be turned or pivoted.
Now you can slowly move the Super Sensor from one side to the other above the possible object. The
Super Sensor cannot swing, it must remain in the vertical orientation. Please try to capture the complete
object, which means you should measure beyond the edges of the object. Repeat this measurement a few
times to get a clear signature of the object. There are 3 different signatures, from which you can
recognize a specific characteristic of any target.
The figure 6.4 shows a typical signature of a ferromagnetic metal like iron. The signature includes a
positive (red) and a negative (blue) amplitude. When looking closely you can see even 2 ferromagnetic
signatures. The first signature starts with a positive amplitude and the second signature starts with a
negative amplitude. The order is not important, it depends on the direction of movement of the Super
