OPERATING IN DISCRIMINATION MODE
Discrimination is used to eliminate trash metal objects (e.g. nails, foil, pull-tabs) from
detection. The searchcoil must be in motion to detect metal. The Discrimination Mode
is less sensitive to small and deep objects than the All Metal Mode.
This feature is not available in Discrimination Mode.

Computerized Ground Balancing
Your best results will be achieved by first performing the Ground Grab
Ground Balancing procedure in All Metal Mode.
The ground balance setting achieved using Ground Grab
Balancing will carry over into this mode.
As you adjust any of the controls, notice that the values on the bottom-right of the

hear any sounds when the searchcoil is sweeping across the ground, with no metal present.
Start with GAIN at the 12:00 position, or less.
In this mode, Gain refers to the detector's sensitivity. The higher the setting, the deeper
objects can be found, and the more sensitive the detector is to very small metal objects.
The right knob is not used in the Discrimination Mode.

Unwanted Noise
This is a highly sensitive device.
It is intended for use outdoors. Indoor operation will subject it to electrical interference
from a wide variety of devices in the home or office.
In Discrimination Mode, when you sweep the coil over the ground it will usually be quieter
than when holding the detector still.
As you sweep the searchcoil over the ground, try to keep the coil parallel to the ground.
Sweeping the Searchcoil
Avoid lifting the searchcoil at the end of your sweeps.
