F3Ci Operations Manual
15
* WARNING *
When detecting targets with low metal signatures, the F3Ci should
not be used on a selection lower than the default setting (Position
4). Where possible, Free From Explosive targets should be buried
at the required detection depth. Sensitivity options (Positions 4 to
7) should then be tested to determine the most suitable sensitivity
to ensure detection of the target.
3.1.3 Ground Balance
Located on the right hand side of the LED display, when pressed and
released the detector will commence its Ground Balancing sequence
to remove the effects of mineralised soils.
3.1.4 Noise Cancel Button
Using the Noise Cancel button located on the left of the LED display,
the operator can initiate an automatic frequency scanning sequence.
As a result the F3Ci will select an operating frequency that minimises
the effects from sources of electrical interference.
3.1.5 Mode Select Button
The yellow Mode Select button can be used to toggle between:
a. Detection Mode. This mode is the default mode for the detector
and will provide a similar tone to all types of metal targets. The
tone will vary in volume depending on the size or proximity of the
target.
b. Interrogation Mode. When selected, this mode will provide
different tones for various targets.
c. Pinpoint Mode. By selecting Pinpoint Mode, the detector provides
a single tone that assists in determining the accurate location of
the target.
