Ground Balance mode (Balance 1 and Balance 2)
To get the best results from your SD2100v2 it is important to know how
different ground conditions affect the detecting process.
The ground is made up of many different chemicals, minerals,
salts, etc. Some of these (which are often referred to as ‘ground
mineralisation’) will produce a response known as a ‘ground noise’ from
the detector.
The SD2100v2 has the ability to cancel out the effects of ground
mineralisation so that it minimises ground noise, while still retaining
maximum sensitivity to metal targets.
Cancelling out the effects of ground mineralisation is referred to as ‘ground
balancing’. This ensures that welcome signals from objects such as gold
are not confused with unwelcome ground noise.
The Balance 1 and Balance 2 controls should be adjusted with the Search
switch in their corresponding positions. If the effects of ground mineralisation
are not balanced, signals from metal objects can be very hard to distinguish
from ground noise.
