• Decimal – ON/OFF depth indication with decimal point (upper right side
of display) during searching (toggle center position) EXAMPLE: 26.5.
• Fraction – ON/OFF fractional depth indication (upper right side of display)
during searching (toggle center position) EXAMPLE 26 .
• Size - Selects the size of the depth indication during searching (toggle center position).
Spectragraph – Selects options for the block spectragraph during searching
(toggle center position).
• Consistency – How quickly an individual spectragraph bar builds height is based on the
consistency (average) of the target signal after multiple search coil passes. By adjusting
consistency, spectragraph bars can build quick and narrow, or slow and wide based on the
targets characteristics.
• Max – Higher numbers allow less target consistency for an individual spectragraph
bar to build height. Lower numbers require less consistency to build height and have
the effect of more readily indicating wider spectragraph patterns for inconsistent
target signals.
• Intensity – In addition to indicating the average target indication, Spectragraph bar also indicates
the intensity. Spectragraph height is based on the (average) of signals and intensity at that
particular VDI number.
• Base Threshold – By adjusting the degree or % the first spectragraph segment
represents the target signal strength, and intensity (height of spectragraph blocks
or pattern) can be adjusted to preference.
• Single Sweep – ON/OFF. When ON, spectragraph represents only the information from the last
sweep of the search coil. When OFF, spectragraph averages information over multiple sweeps
of the search coil. Averaging provides more accurate spectragraph information. However,
in clean ground with attention to search coil sweep speed, an expert may find Single Sweep
setting an effective method of searching.
• Fade – How quickly the spectragraph information fades from the
in a Single Sweep.
• Higher numbers fade (clears) the spectragraph more quickly. Lower numbers
slows fading. Select a fade rate that allows enough time to consider the information,
display overload.
• Resolution – Adjust how many VDI numbers contribute to a specific Spectragraph bar.
• A higher number (larger range of VDI numbers for each bar) will produce fewer
and wider Spectragraph bars (the entire VDI range is split up into fewer bars).
• Lower numbers produce more and thinner Spectragraph bars (the entire VDI
range is divided or split up into a larger number of bars).
• Compress – ON/OFF. When ON the iron Spectragraph range (-95 to -1) is minimized,
allowing a larger area for the + range, adding to the resolution of the + range.
• Rule – ON/OFF. When ON (-95 – 0 - +95) reference is shown across the bottom of
the Spectragraph. When OFF, no VDI number reference is shown.
• Size – Select the size of the (-95 – 0 - +95) reference rule.
• Disc Bar - ON/OFF. When ON, the color bar across the bottom of the Spectragraph
indicates the Accept / Reject discrimination program or settings.
• When Rule ON, selects the size of the Disc Bar.
• Multigraph – ON/OFF. When ON, each primary frequency currently in use indicates
with a separate Spectragraph. When OFF, only one Spectragraph appears regardless
of how many frequencies are in use.
