BIG FILTER [Off/1-9]
(filtering of large objects) The purpose of this filter is to
eliminate an audio response from larger objects based upon their size. When set to
OFF this filter is disabled.
When this filter is turned on the software estimates the size of the target.If the size
is LARGER than the selected value the audio response is eliminated. Response to
target size is also based on sweep speed. At slower sweep speeds the duration of the
interaction between the object and coil is increased and as such smaller targets than
desired may be eliminated verses say a faster sweep speed. So a constant sweep
speed is important to maintain a consistent size filtering.
SMALL FILTER [Off/1-9]
(The filter of small objects) Works similarly to the
Large Filter accept in reverse. When this filter is enabled the software estimates
the size of the target if it is LESS than the selected value the audio response will
be eliminated. Again this filter is dependent upon a constant sweep speed for
consistent results. If you slow your sweep speeds larger targets may be rejected.
SPEED of AGB GROUND [Off/1- 9]
Defines the speed the detector automatically
tracks changes in ground mineralization. When set to
OFF
automatic ground tracking
is disabled. Increasing this setting increases automatic fine tuning of the ground
tracking. When enabled the letter
T
will appear on the left side of the display.
When disabled the area on the display will be blank. While in Autotrack if the
device has carried small fine tuning adjustments the letter
R
appears.
ANALOG MODE
Defines the operating mode the detector is operating in.
When set to
Off
, considered VDI
Mode On, the device continuously
analyzes the information received from the coil and stores this information
in memory. It then analyzes this information and generates an audio
response, the hodograph display as well as a VDI indication based upon this
analysis.
When set to
On
, considered VDI mode OFF, the detector simulates an
analog device. The sound indication occurs continuously in the real time.
The hodograph and VDI occurs in a manner similar to mode
OFF
.
GROUND COMPENSATION [Off/1- 5]
reduces false signals which appear due
to non uniformity of ground minerals as well as “hot stones". There is a clipping of
sectors around VDI +90,-90 numbers. Increasing this parameter improves the
quality of detuning from the influence of mineralization. However, this reaction
worsens the response from large non ferrous objects with a VDI close to
+90
.
