IRON DISCRIMINATION
IRON SWITCH
In general, when searching in wet salt water beach sand, the most ideal settings are the maximum level of the iron discrimination,
iron switch off and mineral 2 or 3 modes. You can also use these settings when searching in wet plowed land with high iron effect.
2) It enables metals containing iron to produce a low tone and to be discriminated more easily. Discrimination starts at about
level 4 - 6. Below this level, all metals including iron will produce a non-ferrous (high) tone and generally speaking the device will
perform at its maximum depth. In addition, iron switch will not be active below this level.
This setting is designed for tough ground conditions and experienced users. For normal
ground conditions or if you do not want to bother with this setting it is recommended that
you keep it at the factory setting (FS).
This setting has 2 main purposes:
1) Especially in areas of high iron mineralization and wet beach sand you may not be able to
ground balance the device. In such a case, you can use iron discrimination. By turning the iron
discrimination knob to the right, you can enable the ground effect to be reflected as iron and
eliminate it by turning the iron switch off.
When you want to avoid detecting ferrous metals you can turn the iron switch off and enable
the device to eliminate these metals and not produce a warning tone.
NOTE: Many metals considered to be trash may not produce a ferrous metal signal. For
example, pull tabs may be sensed as a non-ferrous metal by most detectors because their
signal is very similar to that of gold.
