SENSITIVITY
For maximum depth, do not turn the ground balance knob to the right more than necessary.
Generally speaking, the mid-level (between 4-7) offers the most ideal and stable detection
capability on different types of ground without sacrificing depth.
As the ground balance goes into the right area, the device will start losing depth for some
non-ferrous metals except for gold. When the ground balance setting reaches the maximum
point the device will detect iron and gold but it will not detect some non-ferrous metals.
If you are searching on a ground loaded with mineralized stones or dips and holes, it is recommended to ground balance over
one of these stones or the holes.
In areas of very high mineralization, ground balance may not be sufficient. In such a case, you may need to use the mineral
search modes (see page 16).
Sensitivity setting is used to eliminate interferences caused by electromagnetic waves in the
surrounding environment or ground noise. Electromagnetic waves may result from power
lines in the surrounding environment or from the operation of electrical devices, radars,
wireless radios, and even TVs.
Sensitivity is also the depth setting for the device. Therefore, especially in high
mineralization, it is recommended that you lower it only if the device is still getting noise
after you adjust all the other settings (ground balance, iron discrimination and mineral
modes).
